Ok , suspension was from ebay as were the axels.
wheels came with truck under a dodgey trailer.

Hi calum.
dont have any pictures of the crusher plate.
what I did to fix the bottom was drill and tap some 6mm holes at the bottom of the crusher plate.
I then used some 6mm bolts ( quite long) and put some heavy compression springs in between the plate and crusher box.adjusted lenght of spring to get correct angle on plate.
you will have to slot these holes through the box to allow a little up and down movement
job done.

Okay I think I understand what you mean, any idea what speed you will be running it at?

[andyathome]

Hi calum.
un decided yet , have a 1200 rpm motor fitted but still waiting on belts for drive.
it appeared to work with battery drill on main fly wheel at around 400 rpm.

thats why I will power conveyors and crusher drive off power supply, so I can adjust on the fly to tune it with the material im running..

Did you make yours like a cam? So it moves like this

https://www.youtube.com/watch?v=5b0557iAbP8

Or did you just offset the bar so it pushes against the crusher plate and pivot it at the bottom?

Calum

[andyathome]

Hi calaum. Thats exactly how I made mine.
I found several animated videos on youtube and copied the design.
I have a shaft drilled off center that the plate attaches to, two bearings in crusher housing .
I threaded the shaft and used 6mm bolts to hold weights to shaft.
You will need to drive the crusher in the right direction , so the motor tightens to bolts on the pully.
other wise pully will disappear across the room rather quickly.
dont ask me how I know this LOL.

cheers andy

[andyathome]

the truck is alive.
had to remove the original gear box and fit a geared motor to give me more room in the cab.
sound card is now fitted and really happy with the polou motor.
can drive all day long with 5 plus kgs in the tipper.
I think the pump is straining a little ,but it still lifts at the same speed if its full or empty. don't know that that is normal?
just a quick test video

[andyathome]

got motivated to finnish off truck, and made a start on trailer.

heres a few progress pictures.

pump in and running, home made stainless tank holds just enough oil.

cant fit cab to rails as too much inside, had to swap gear box for a geared motor, so printed up a motor housing and fitted sound modual under battery plate, speaker fits nicely in front grill.

[andyathome]

trailer now has a bit of colour.
pump fits nicely between chassis rails, so now have to make a tank to sit in behind the pump.
I will use a deans plug fitted to the back of the truck so i can plug in the trailer.
the esc for the pump will live in the cab.

heres a few wet paint picts.
PS the coffee cup is to hold me and the trailer up as its 3am :o

Would that be you blocking the road with a jack knife b/c you missed a shift? :p :D

What voltage are you running this trk on?

[andyathome]

Nah blocking road cause its top heavy if overloaded . LOL
I can see a few accidents in the near future.

its running on 7.2v but im useing a 12v drive motor.
truck came with hyd pump ( dont know what brand it is) it is a small black square plastic unit.
You wouldnt know what is max voltage for these pumps as I would like to speed it up and possibly run a 11v battery to get a higher rpm on pump.

cheers andy

[Lil Giants]

The telescope cyl looks like a wedico (probably is) & the pump would be 12v. 3s would be a little slow yet, but better than 8v / 6cell.

[andyathome]

Thanks joe.
yes it is a wedico ram , and that is good news that I can run it on a bigger battery.
I also have an old wedico merc truck ( mint condion) that I got second hand with no battery.
the old guy I got it off built it as a shelf model and never run it and had no paperwork ( instructions)
so can I assume this is also 12v powered.
ive had it around 4 years and might have a go at getting her up and running before winter ends

thanks for your help

cheers andy

[andyathome]

this is the truck im referring to.
haven't pulled it apart to check if its all there but from what I was told it is complete and needs a battery and radio to run,
she is a little dusty.....

woke up this morning and looked out side.....

its not raining.



so heres a picture of the set up in the sun....
got to fit some lights , and a few cosmetic things to sort out.
need to get some 12v esc,s (x3) then I can power up trailer.

more waiting for the post man.

and what ever the wife said to the dogs worked, the spa cover is still in one piece :lol:

heres a quick video of truck pulling trailer.
battery was flat so sound cuts out and its a little slow.

worked pretty good but will fit a 4:1 box to give it a little more torque.

[jack van]

:eek:so andy is the gate there to keep the trucks or us visitors who want to play with them out lol nice truck and looking good:cop:

[andyathome]

LOL.
im pretty happy with my first serious truck reconstruction.
doing one bit at a time but thinking how it will all work at the end wasn't that bad.
the gate is always open to people who want to play.
its mainly shut to keep the two rotties and one stupid british bull dog from running off with the mrs shoes, or what ever takes their fancy.

took the youngest rottie for a drive yesterday, he was really excited...
not too impressed when he woke up!!!

should have been a vet , cost me the price of two semi trucks.

no more double due claws and no more dangly bits for him. :eek:

Yes, 10 cell NiCad or NiMH. 3s might work too, not sure if the wedico electrics will work on a lower voltage.

[andyathome]

thanks Joe, have ordered a full set of esc,s ( 3 ) at 12v and robbed my road roller build of the dx6 receiver , also got a 11v lipo battery on its way.
so truck will be running at 11v , hopefully the rams will move a little quicker.

fired up the wifes decal cutter and had a go at some company name decals.
I need to make a loader and excavator picture to put on either side of the company name to give it that finished look. :o

Ps the dog is fine, and up to his old tricks of mass destruction the following day.
his partners in crime have destroyed the bucket on his head and freed his feet from the bandages.
so I played doctor , new bandages and some time in isolation to give his stiches a chance to heal.
last thing I want is a lecture from the vet. :D

[andyathome]

got the go ahead to open up the summer quarry again.
someone filled it in due to health and safety requirements, so I have to start again. :cop:
better get a chilly bin and a few beers organised.
need to make a few roads and clear some of the rocks to make driving more pleasant and safe.

heres a quick video of this mornings efforts.

https://youtu.be/sskVcqWUALQ

cheers and

[andyathome]

ok, so joe might know a thing or two about RC trucks.
I took your advice about the pump , I have replaced all Tamiya electrics.
The post man showed up this morning with 3 big 12v esc,s and a 11v lipo battery.
2200 battery so its nice and small and fits nicely in the cab but will be interesting to see how long it lasts, hope fully around the half hour mark or more.
made a quick video of the truck lifting the bed unloaded then fully loaded with around 5kgs of dry dirt, I am more than happy with how it works :):):):)

now I just want it to stop raining so I can have some play time.

http://youtu.be/0fdRE-eYsC8

wow that moves alot better looks about right for scale speed very nice

[andyathome]

that would be cause you guys drive on the wrong side of the road....LOL
and hes not old enough to get his licence just yet.

cheers andy

[andyathome]

bit of an up date.
trailer is all ready to go but the pump/cylinder I got of a guy is no good
pump cant make pressure, really slow.
took pump apart and there is a lot of ware marks.
so I guess I need to find another wedico type pump.

still , it was a cold and foggy morning and I had the urge to fire up the king haulers.
attach one now 41kg crusher on the lowboy to the tri axel, and send the dump truck off into the fog.
have also fired up the loader to clear the new dig site for summer, but that's another video in the making.

this one is of the trucks being trucks

cheers andy

[jack van]

looks like you have a large chunk of property how many acres of land ?

[andyathome]

we have down graded from 35 acres to just under 5.
but it seems that the smaller plot requires more work to maintain it.

I guess you can see it all therefore you cant ignore it, and im sure the Mrs's eyes have got better.

just finished replacing a septic tank pump........ yuuummmmy job. :mad:

still tomorrow is forecast for good weather so , more truck and excavator time.

cheers andy

[andyathome]

loader cleaning a path to the dig site
a lot of roots to deal with, will need the excavator with ripper to do the job.
we will see how smart this site is.
may be back to the gravel pit , time will tell.

had enough of tree roots so, the dozer was fired up.
Im thinking a little manual spade work is also needed.

Nice set up

[Supermario]

I just read through your entire thread and noticed a few things. First, what a great fleet and a lot accomplished! :cool:

You asked me way back when what kind of run time I get out of a 8400.
Now that I have motor speed correct and some time at the controls, I get a solid hour and a half run time. I've got 2 of them. A .gens ace and a traxxas. The gens fits nicely, the traxxas is a little bigger and a snug fit.

I'm glad I did read through, I don't know where the heck I was but I had missed a lot of great info from you and Joe about radio settings for the 4200!

Thanks again for sharing and can't wait to see what's next. :)

[andyathome]

im very much like you, no more building until winter starts again. LOL.
but having said that Ive always wanted to build a scraper to be towed by the dozer.
I have wheels and servos already so......

[andyathome]

spent a rainy day in the pit .:D

[andyathome]

I might have to look at the bigger battery option, thanks Mario.
I don't think Ive ever had a group family photo of the construction company,
I do know it has grown ever so slightly so I took a couple of pictures of my addiction.

Im going to need a bigger shed to store them in. :jaw:

[Supermario]

Family photos can really put things into perspective. That's why I stopped taking them. Lol.
I wonder what life would be like if I had a neighbour like you. :D
Probably be divorced in no time :lol:

Sweet fleet Andy!

[andyathome]

divorced and broke LOL
showed the wife the photos, her comment was "I thought you had more than that"
So I better start building a few more.
going to do some googeling on scrapers for the next project.

cheers andy

[jack van]

you would likely have the best back yard ever haha

[andyathome]

I finally had a bit of spare time to play with the radio settings for the loader.
I've slowed the steering and bucket drop speed and it looks way better.
next on the list is main drive acceleration.
I want to slow that , but first I need to charge the battery again.....

https://youtu.be/a1kDuEwNe7U

[andyathome]

I had a play with the hyd system in the excavator.
I pulled all the servos off the valves and centred them.
man I wish I had done this years ago, so much better and easier to control,
next on the list is to sort the slew motor, I have wear in the shaft and gear causing the wobbles when you stop the movement.


heres a quick video of the before and after :)


https://youtu.be/bLsvjFPvOsI

[Supermario]

Running great Andy. I can't imagine operating with a drifting boom, bet your happy that's gone.:)

The sloppy slew. Did you try to snug the motor pinion up to swing gear at all? I've got excessive slop also but notice there is some adjustment possible. Going to wait until winter shut down before dealing with it.

And happy summer to ya! :)

[andyathome]

cheers Mario,
yes much happier with the operation.
when I first got it I pulled it apart to see how it worked...
guess I put it back together a little wonky and always had to issue to a small degree.
I remembered reading something on this forum about centring the valves , gave it a go and discovered my mistake now it works great.
the problem with the slew is a worn motor shaft, too much slop between shaft and gear.
looks like the grub screw was always a little loose and scored the shaft, a new motor should fix the problem.

Im on a quest at the moment to get a 1969 Plymouth road runner and may end up having to get on a plane and visit the US to view a few . Have a guy here who dose this for a job ( friend of a friend) but our low dollar is making things a little expensive
Have been told by the Mrs that I cant load up the container with RC toys " your going for a car and that's all".....
not a hundred percent sure what she means by that but if any one can recommend a good model shop in or around Arizona I wont say anything....

cheers andy

[andyathome]

had a little play time so I had another go at the radio settings for the loader.
so far I have dropped the steering speed by 50%
bucket drop also set at 50%
and main drive motor max speed is at 40% in reverse and 50% forward.
I could have just used the switch on the radio to lock the diffs and slow it down but I figured leaving it unlocked it would place less stress on the axels .

pretty happy with how this loader is working now, just that dam noisy pump....

[osikasculptor]

Hey Andy,

Why the Bier sound card? Did the other one stop working?

tao

[andyathome]

I had the beier sound card sitting on desk for a while and I want to get the hydraulic fluid sound thing happening when the rams move and also a few more realistic sounds happening.
also, I stole the sound card out of the excavator for my KH dump truck build.

I need to spend a bit of time trying to work out how Im going to do it , but I have a plan...
just need to find the time.

cheers andy

[andyathome]

while the wife is off having a good time on a girls trip over seas I have been tasked with getting the vege garden sorted...

Step up the excavator soon to be followed by the loader.
not sure how I will plant the produce in the ground but at least I've made a start.

a quick video so far


https://youtu.be/UR8AO0sguqI

[andyathome]

made a few changes to the dozer, fitted some aluminium track runners to stop the tracks coming off.
not quite right as you can hear the pop rivets holding the track pads hitting the runners.

out with the grinder tomorrow.

heres a quick vege garden video

https://youtu.be/A6SouJ-90hE

[andyathome]

summer is on its way, found a possible track to run the semis on.
problem is that it is at serious altitude, with a 6 - 10 foot drop [roll to the bottom] . which wouldn't be good for the trucks.
got the excavator in to make a start on the road but will need the dozer and a water cannon to clear most of the really hard dirt before I can start to make a driveable road .
just happen to have a Polaris ranger, a generator and water pump , so that part is going to be easy.
almost lost the excavator a couple of times but the camera must have stopped..... like my heart. :eek:
here's a short movie of what Im up against

much bigger and complete with fans.

so hashed up something that will do the job.

[andyathome]

made a start on another project that has been sitting in the shed for a while now, the mighty KAT excavator.....
I know its lightly built and basically rubbish, but I think I can make it a little better than when it arrived.
The base was slightly bent and a little wobbly, just too lightly built.

a $80 purchase of a 3mm thick steel half sheet and the job begins

Im going to use the same set up as in the rc4wd excavator as I have all the parts already.
I have ordered 3 large ecs,s for the tracks and turntable , now its just a matter of making it all fit inside.

I used the original base plate as a template for the top half and reproduced all the other panels and welded them together to give it some more rigidity

wasn't happy with how the way the main boom rams were fitted , so added an extra mounting point to stop any possible twisting.

need to sort a few panel gaps , also instead of a counter weight at the back I may make a built in oil tank to save a bit of room for the electrics.

a new bucket and quick release is also in order as is rebuilding the track set up.

but first mission is to get it digging for the summer and the youngest will be happy.

basically I think I will be using the KAT as a template to build a whole new excavator. :o

[andyathome]

So as it turns out the KAT is only good for a template..

made up a new set of booms out of 3mm sheet and welded them up.

I have predrilled the pivot points but will make up some brass bushes and stainless shafts.

This isn't turning out to be a ten minute job.

a little CAT code paint make it look better

Looking good Andy. Always nice to have a second digger. I really like the 4200 upgrades. The cat walks is a nice touch.:cool: Tracks look a little loose though?

[Supermario]

I can't remember, do you have an interior in the 4200? And have you seen this? I just discovered a few days ago..

[andyathome]

cheers Mario,
yes the track tensioners need looking at, hopefully just full of dirt :o

I have seen that interior and at 89 pounds , nearly $250 kiwi that wont happen anytime soon :D

the cab on the 4200 is a cheap ebay special, quite a bit smaller than the standard but it came with a complete interior.

Looks good Andy, and keep those outside pics and videos coming, you are heading into summer and I'm watching the leaves drop for winter. So it will be nice to see some sun and green with your equipment working :)

[andyathome]

still waiting on paint to dry on the arms, so I used up the original decal sheet that came with the excavator.
Young fella likes it so that will do me.
crammed the esc's into the front of the excavator , mounted pump and valves.
still have a little room to play with but will have to make a new tank as its slightly too high and cant close engine cover.

[Supermario]

wow Andy, the new digger is looking good. Is it just me or is the upper structure much longer than a 4200? Ouch! I forgot about the exchange rate and I think you have a much better alternative for the interior. :cool:

Wondering how the crusher project is going btw? Haven't seen much on it lately.

[andyathome]

hi Mario,
Side by side the two excavators are almost the same length in the upper structure, did toy with the idea of adding 50mm to the 4200 but it was getting too hard and couldn't be bothered.
It may happen at a later date.
the crusher is still not running, I have the attention span of a house fly and am never happy unless I have too many projects on the go at the same time.

cheers andy

[andyathome]

more brilliant NZ weather , so I spent some time in the shed.

walkways, exhaust , air filter and all hydraulic lines done.
All joints bushed and sleeved.

Also made up a mechanical thumb.
This still needs some clean up work and painting.
when the thumb is down it has a latch that holds it in place, which I want to revisit as its a little rough. :o

I might have to look at the bigger battery option, thanks Mario.
I don't think Ive ever had a group family photo of the construction company,
I do know it has grown ever so slightly so I took a couple of pictures of my addiction.

Im going to need a bigger shed to store them in. :jaw:

Amazing job piecing your fleet together! Really like the changes you to your 4200 looks bloody awesome! :eek:

[andyathome]

thank you, I like the new look but the more I look at it , it looks too short.
Just another job to do.
think ive found the solution for my thumb on the CAT.
doing a bit of youtubeing this morning and found this, super simple .:eek::cool:

[bigford]

andy are those the 4200 cylinders on the cat? she is looking good!!!
i have 10 months to get the kat digging for a long road trip to canada

[andyathome]

hi bigford , no the KAT is still going to be using the original cylinders, but I will be turning the pump speed way down, and see what happens.
This was supposed to be a budget build using all leftovers but we all know how these things get out of hand....

I had a plan to make the thumb mechanism today , but things changed.
Mario asked a simple question on the length of the KAT compared to the 4200.
Over night I hatched a plan, any way heres the results, still unpainted but structurally completed.

I think it looks way better 50mm longer. :D

[Supermario]

Looks great! Now I see it and realize what a short tail end the 4200 has.
The reason I asked the question in the first place was the pic you posted showing the pump and valve next to each other on the right and battery laying front to back behind cab. Seemed like more room. Speaking of room, did you gain lots of space to rearrange things inside?

[andyathome]

the KAT has a bit of room in it , but now the 4200 has more.
Im going to leave the original placement set up in the 4200 but will now place battery next to counter weight across the back of the excavator as there is a lot more room at the back, and it will make changing battery easier.

now I have run out of paint , so maybe get started again on doing the KAT thumb.

cheers andy

[andyathome]

more progress, but I have a question .
Ive made some solid lines out of stainless tube to fit to the main boom, just sitting on there temporarily , but before I cut the plastic lines .
How do you guys seal the fittings on.
Ive tapped them at 5mm which is the correct size for my fittings , I will change the bottom fittings for right angle fittings, but do you use any sort of tread lock or sealant.

I have made some access panels to cover the ugly air vents, and will run a fan at the top of the engine cover to take hot air away.

[Cooper]

As far as the fitting for hydro lines , the fittings should have a plastic washer. That makes a seal on the flat of hardline. If you using the stainless turn the ends perfectly square to the pipe. That will give you the flat seat for the plastic washer to compress and seal. I'll try and find a good pic.

[andyathome]

cheers cooper,
I spun them up in the lathe, so nice and square, just worried the plastic washer wont do the job and end up with a big sticky mess.

thanks andy

[andyathome]

had to have a quick play

https://youtu.be/fGXRBMoZsYc

cheers andy

[andyathome]

im a happy camper....:D
very reluctantly cut the first hydraulic line ...
then another until all cut and fitted in their new home..

turn on pump and close eyes..

only one leak for the bucket curl at the end of the long line outside the excavator..

now I need to find some more bolts so they all match, and make a few clamps for the long line on top of the boom , and shorten a few lines.
then it all can go into the paint booth.

had to test it out properly , one hour of digging , no leaks and really happy with how it looks now.

the seal that leaked was the rubber o ring on the fitting.
I had a few spares but they are copper washers , so replaced all seals with copper ones.

got a deliver out of the paint shop today.:D
also made a whole lot of little brackets for the solid lines , rerouted the light cables in hydraulic hose and used an original hose clamp to hold the ends of the hydraulic lines behind the cab.

Quite a transformation! Great job :jaw:

[Supermario]

Quite a transformation! Great job :jaw:

Absolutely agree. it's hard to spot any old 4200 and has now become a very nice hard rock mining shovel. Nice work Andy, I'm jealous but also motivated to tweak mine a bit, thanks! :D

[RCP57]

Looking great Andy! By the way, did you find a Hemi yet?

[andyathome]

Yeah .
found a couple that im realy keen on , gota wait for the guy to inspect and make a decision.
wife wants a 69 mustang so will do a double container and ship them both back home.
then we will fight over shed space.:D

Haha, yes my wife has wanted a new Cadillac for a while now and when it happens there will definitely be a fight over garage space here. Our garage is full already(too small) so I guess something of mine will get the boot. What engine are you looking to have in the Mustang? Big block?

[andyathome]

this is going to sound stupid, she wants the looks of the mustang
but she is talking about a 6 cylinder model.?????

now if that is what she wants to pay for Im not going to argue ...

but I may try and talk her into a 289, at least that way once its here we can upgrade it to a bigger motor legally ,due to NZ's over protective vehicle modification rules

cheers andy

[andyathome]

no digging with the 4200 as we were rudely interrupted by guests bringing beer and steaks.
so dragged the old go cart out and taught the wife what more power means:D

a few sore heads this morning but no one is dead , so all good.

[RCP57]

Oh that's good. The Big block Mustangs are a pain to work on. Pretty much have to pull half the car apart to remove a valve cover let alone do any serious work.lol A 289 or straight 6 will leave some room for your hands between the shock towers at least.

It looks like the carting was fun as well! Friends only show up at our place when they want something....

[andyathome]

so, with the 4200 nearing being finished , I stopped working on it and started to finish the thumb for the KAT .
I used a 8mm stainless tube and slid a 5mm solid shaft inside to make a fake cylinder , welded a couple of nuts on the ends.
I drilled a couple of holes in the shaft and used a clip of an old rc car to hold it in place, seems to work.

painted and done.

sorry Joe but I stole your idea.
been sitting on night shift for the last 4 nights, and your grinder attachment was giving me ideas on how to build the cliff road.
way too hard to dig now but a grinder , now that might work.
Ive robbed the drive for my roller build ( it will be too slow but its the same size).
ive made a few shafts and cut on an angle and temporarily
glued a sprocket on.
(cant weld stainless with my mig today)
but it looks like it might do the job.

just a quick test to see how strong the super glue holds before welding

seems to hold for a bit

DAGNABBIT ANDY :mad: :mad: :mad:


I KNEW I was over thinking this!!! :D :lol:

I like your idea muuuch better! much simpler, less moving parts & it looks like the Alpine cutter Neil posted a vid of. :cool:

So what's the rpm of this motor gearhead & where did you get it? To go higher rpm = less torque :thinking: What about just going with a bit bigger diameter sprocket?

And I really like how you attached the sprockets at an angle... Genius! :cool:

My grinder is going in the bin & I'm building one like this. ;)

[andyathome]

yeah, watched too many cutter head videos over the last shift.

it is a 35rpm motor box at the moment, looking at probably three times the head speed for the new set up.

I got the gearbox motor set up from aliexpress , but this is the one Im thinking of getting, do You recon it will be fast enough.

I really didn't know if it would work , but it looks like it will work like the alpine ones on you tube and the sprockets will achieve the same thing, so we will see what happens


cheers andy

[Lil Giants]

Great! thanx for the link. Do they do PayPal? Check tomorrow to see what rpm my gizmo is running at... your current sprockets, are they 25mm diameter?

So what's happening with your jaw crusher? I thought we'd be seeing an action video long before now :confused:

[andyathome]

no, pay pal is not an option.
get one from someone who has had lots of good feed back and all should be good.
the sprockets, I think they are 15 tooth, may be 50mm diameter sprockets, the hole grinder is only about 150mm long and I thought about scale, for a bit........used what I had.
If I add another sprocket on each side it will double the work load, and hope fully not the heat...

[Lil Giants]

Found something similar on ebay, maybe it'll show up before xmas.

http://www.ebay.com/itm/321614113867

[andyathome]

that looks the same as mine and I think the rpm's will be better.
as for the crusher , that was supposed to be the next job until I saw your grinder attachment.
so you will just have to wait until im done with my grinder LOL.
good thing is now that the roller has been gutted of parts for the grinder I now have all the rc parts I need to make the crusher mobile, but still have to make some adjustable motor brackets for the crusher because I cant find the right size belts.
one day it will happen, but for now its summer and I really want to make a start on the cliff road with my grinder.

cheers andy

[andyathome]

did a little more on the grinder,
I have shortened the collars on the sprockets to get them in closer to the head, and it should work better closer together.
and of course I have painted it before its finished, made a few brass brackets to hold wiring but a few more to do yet.

I think I will weld sprockets on and bore a hole through the sprockets so at a later date I can just put a shaft into the hole and add another set of sprockets if I need to.

[andyathome]

more progress but a little slow.
made more brass brackets and fitted a solid line for the cables to power the grinder, and then run out of paint......:mad::mad:

Need to do something about the wires on the bottom arm as I think they look like C@#$p.
also want to widen the track base by about 15mm each side, will be easy enough to make some spacers up and longer bolts.
But that's a job for tomorrow

[andyathome]

today I finished the painting and cleaned up the cables on the bottom arm and installed two new toggle switches on the engine cover, 1 for the lights and the other for the grinder which is fused at 3amps.
also had to repaint the arms due to the new colour matched paint was different, spoke to the paint lady and she said sorry and gave me two cans for the price of one :D

Then I made up some spacers for the track bodies, 15mm wider on each side.
this has now caused me another problem, as it only just fits on the lowboy :o
I need to rewire the track motors now because the cables are too short, and I found out why I blew a track esc, wires way too short and shorted together :mad: :mad:

[andyathome]

well Im back,
had a small problem with a truck load of lightning .
basically it blew all the telephone jack points off the wall, fried the big TV and all other associated electrical things on that circuit, melted the TV aerials, toasted the wifi modem ect ect.
the insurance company loves me now, but at least nothing caught fire.

So, with no internet or TV I headed to the shed.

have been playing around with the grinder and need to make a few changes, I need bigger sprockets as the motor bottoms out too soon when grinding, also ordered a quicker motor.
Will try the bigger sprockets first and see what happens.
heres a quick video of the grinder at work, and a little taster of another idea I had, this needs some more internal work and more speed , but I think I can get it to work

Andy, your video's marked private.

[andyathome]

I suppose it helps if I click on the publish button :D

[Supermario]

Welcome back and glad to hear all is well after the fireworks and all. :eek:

The grinder definitely needs larger diameter sprockets but I don't think you'll need to up the speed. Can you also maybe change the bottom of the drive from a flat surface to something more knife edge or tapered a bit.

How much larger of sprockets are you thinking of using?

The hammer, :cool: But you need more speed there for sure.:).
Keep it up, looks great!

[andyathome]

cheers Mario,
bigger sprockets are a must, but cant change the flat surface as that's the bottom of the gear box.
I think I will look at another 10mm in diameter (60mm), I will see what they have on their shelf and its gota be cheap.
and the hammer, yes there is a lot of changes needed.

cheers andy

[andyathome]

had to rebuild the road I destroyed with the grinder, so took a little time and had a play while thinking about different ways to do the hammer.

Is that a bruder conversion next to 870? Was looking for a size comparison photo.

[andyathome]

it is a bruder , but not converted.

[Lil Giants]

It's kinda sad to see this thread not updated regularly anymore, you have a lot of innovative ideas built with basic tools & good ol' fashion know how... hope to see you back 'er someday soon Andy, long overdue to see that tracked crusher in action. ;)

[andyathome]

hi Joe,
yes way too long but with starting my new business running a small excavator and truck theres just not enough time in the day.

thinking really hard about employing someone to help me out so I can get some more family time and of course play time.
The crusher can move under its own power but I need to redesign the conveyors as there is not enough clearance underneath .
Just need to find 10 hours and she will be finished.

hope fully things will slow down in winter and I can finish it.

[Northern Farmer]

How’s it going Andy ? Haven’t seen you online in a while. Had any time to break out the rc’s ? Roadrunner looks and sounds great :cool:

[skeeter]

the truck is alive.
had to remove the original gear box and fit a geared motor to give me more room in the cab.
sound card is now fitted and really happy with the polou motor.
can drive all day long with 5 plus kgs in the tipper.
I think the pump is straining a little ,but it still lifts at the same speed if its full or empty. don't know that that is normal?
just a quick test video

What RPM 12Vgear motor did you use?

[andyathome]

Hi all and merry xmas and a happy new year.
Im still around and even charged some batteries for a bit of a play, but that never happened.
things are getting more organised so i have some spare time in the day.
because its summer here Ive been getting around as much as i can in the roadrunner and doing a few hot rod shows.

Skeeter , from memory the geared motor in the dump truck was around the 30rpm
range.

cheers andy

[skeeter]

Thank-You, sir for the info.

I have GRU in mine for now, but IDK if the other builds are worth the $$, when one could simply place a gear motor on it, & have the SAME effect for far less!

[Claus]

So glad these photos weren't lost. Love the changes the 4200 went through to become the monster it is today.
