I built a screener out of an old drain pipe and have 2 bruder conveyors shifting the fines. 4 speed controls, vibrator , 2 conveyors and the main tumbler. the king hauler is still waiting for its reduction box .

had to make the pit bigger, indoor digging is so much better in the winter.

Re: JBC limited NZ
 

Andy, you have an amazing fleet of great equipment ! :cool:
Welcome and glad you could join the group :)
I really like what you did with the 4200 upgrades. It looks spectacular. Nice work:cool:

Can't wait to see the processing plant in action! :bounce:

cheers Mario, a bit of paint and a cheap plastic excavator cab and some old panel vents I rescued from the scrap bin, also made a few decals and it looks way better than standard.

hope the youtube link works, first test run of screener, had to get a new vibrator motor recently as the old one spun in its mounting and destroyed the connection tags , so chucked some brass into lathe and made nice counterweight as well, works a treat now.

time to go to work , will post more picts tomorrow.

cheers andy

heres a quick video of the 4200 making a new road up to the trommel

please excuse the learner driver in the loader . he needs a lot more practice.

have used about 10 batteries in loader and it runs like a dream, have also checked diffs for play and wear inside and all is good.
hopefully its only an issue with a few of them .
have been dealing with a guy named Tang at eagle machinery in China over missing front wheel fenders and a few bits and pieces I would like to get for the excavator, cant say enough about their service !
I will be getting all of my rc gear direct from them , TOP GUY and an arsom price.

Re: JBC limited NZ
 

Nice trailer for the new loader. Looks like it has plenty of power.

Re: JBC limited NZ
 

thanks bud,
I try to cut costs and build most of my stuff, JBC started out in a scrap bin and a few hours on the tig and a bit of grinding you have a trailler, some old bruder wheels , paint , job done.
leaves cash left over for the good stuff.

beware learner driver in the pit.

Re: JBC limited NZ
 

LOL, have just checked my post and noticed a small problem.
I asked the mrs to do a few decals on her cutter for the excavator.
I put them on and didnt even notice the problem until now.
Im prety sure thats not how you spell hitachi !!!

I hope you dont have a **** of the week award LOL

Re: JBC limited NZ
 

Haha, I thought you did that as a joke! Oops! You were just trying to avoid any copyright infringement.....:rolleyes:

Nice setup! I enjoy the home built stuff the most. Keep it up!

Re: JBC limited NZ
 

Yeah thats what it was.
contracts now sorted so I can fix up that spelling mistake.
LOL.

Re: JBC limited NZ
 

Love that turbo noise. Great video too!

Re: JBC limited NZ
 

Cheers.
Never had a rc with sound before but now im hooked.
have ordered 2 sound units. 1 for king hauler and 1 for excavator.
loader driver has a long way to go before hes qualified much better in the excavator.
Guess I better change the battery again.

http://i1322.photobucket.com/albums/...ps27c872eb.jpg

got a bit of painting done, want to paint all the light holders and still waiting for front guards to turn up, also have a slight problem with the loader.
one of the rear wheels has come loose and my small nut driver has gone missing so I cant sort out my loose wheel.
I don't want to go to the local hobby shop just yet, It could end up costing a lot.( usually dose , all those shiney things)
cheers for now.
going to redo the decals on the arm as not correct and also theres a few to go on the motor housing .

ps the loader is only allowed inside if it sits on the newspaper LOL.

Re: JBC limited NZ
 

I can't help but drool when I see this beauty.:) Now go get the tools you need and treat this loader right! :cop::D:lol:

Mario

Re: JBC limited NZ
 

Have been shopping.
no nut drivers but I got an air bush kit.
bro coming over tonight with my nut driver so will be sorted LOL.
will paint bits and finnish decals.
then play time.

Re: JBC limited NZ
 

Holy smoke! I thought the top photo was of the real one and I was about to comment and say nice job on making scale decals to match! ! That top photo looks so close to 1:1 and I looked at it several times. The only thing that gave it away was the red color transmission.

cheers for the positive comments, Im trying to make this look right , it getting there, front light brackets in paint and a few more decals done, will have a few beers and look at it, not sure that Im happy yet but getting there, maybe it just needs a little more dirt on it.

Re: JBC limited NZ
 

Hey Andy ,you sure have a awesome fleet ,keep up the great work !!:D

Re: JBC limited NZ

just one more in the sunshine.

Re: JBC limited NZ
 

all right time for some updates.

excavator:
ordered a sound card from eagle machinery ( same as my loader)
and crammed it into the excavator, am running it of the 4th valve so after my Y cable (signal reversing) turns up it should be all go.http://i1322.photobucket.com/albums/...ps2c51085b.jpg

have also made a few decals for the rock truck, http://i1322.photobucket.com/albums/...ps854c2836.jpg

also had a slight problem with the loader.
had a rear wheel come loose from the axial, emailed tang at eagle machinery and got a detailed how to do , remove wheel, remove ring gear, pull axial, pull washer , look inside and find 4 small bolts holding planetary gear to axial housing tighten up and all good.http://i1322.photobucket.com/albums/...pseef4cbf1.jpg
http://i1322.photobucket.com/albums/...ps6279d0f6.jpg

new drive motors for excavator have turned up so will fit those when I have a bit of time, also front fenders for loader here and painted.http://i1322.photobucket.com/albums/...ps51834bb4.jpg

also have eight more diggers, early one morning on my way to the shed for a bit of play time and I spot this. http://i1322.photobucket.com/albums/...ps306eb21e.jpg

heres a real quick video of the sound card, flat battery.
you can see how the revs drop when the sticks are moved, the signal reversing lead will fix this.

cheers andy:bounce:

Re: JBC limited NZ
 

heres a better video showing the issues I have .
sound card wont shut down, because Im using the 4th bypass when there is no stick movement the revs are high.
in order to shut down the sound card I have to stop pump, use a stick , drop sound card revs then use a track and all shuts down.
when the reversing lead shows up all these steps will be gone, hopefully:D

Re: JBC limited NZ
 

Andy you got that machine looking amazing and she seems to be running nicely keep up the good work

Re: JBC limited NZ
 

thanks, since Im not allowed a real one I will stick with the little ones, problem with that is theres all these little things you can do to make them more life like, adding the sound changes everything , then theres lights and paint and ,and OMG this is getting out of control.
time to go and replace track motors and have a play, need to get my RC fix today.

cheers andy

Re: JBC limited NZ
 

Have just finnished installing the new track drive motors.
Found out why the tracks were jumping, I have sheared both pins; probaly due to driving small gravel and ignoring the bad sounds .
I didnt have 2mm by 35mm pins lying around .
measured a few pop rivets and they are a perfect fit.
1 battery flat , new motors work sweet and the pins are still going strong.

Re: JBC limited NZ
 

ok, finally bit the bullet and got another lowboy for the fleet.
was a stock standard rc4wd lowboy but it needed some upgrades.
all the fleet trailers are red so ,out with the spray can.
also cut up some 5mm MDF sheet and used a slitter blade in the grinder to make some fake planks.

Re: JBC limited NZ
 

Nice upgrades.

Re: JBC limited NZ
 

I like this shot Andy

just the right distance and angle to make the Shed look the same scale

nice

Re: JBC limited NZ
 

cheers paul,
waiting for better weather then a few more outside shots.
got the conveyors finished and running good.
need to put loader back together, had a bearing failure in the rear diff.
input shaft bearing toast!
got a new gear set from manufacture (free) and put some shims in around main diff gear bearing, and milled a bit of clearance for the diff lock leaver ,also rechecked front diff and fitted shims, milled a bit out the same as rear diff.
need to find a bit of time for a play to see if it is all good.

cheers andy

Re: JBC limited NZ
 

Nice pictures of the trailer and loader

Re: JBC limited NZ
 

Thanks. Had to get a few while it was still all shiney..
now I need to try several batterys in the loader to see if my fix is going to be long term.
I can see why the bearing failed, just really bad clearance in the castings and a lot of loading.
I see this all the time at work on the cheaper electric motors that are fitted to some of the machines that get installed buy the bean counters.
they wonder why maintenance cost is so hi.
need I say more.
dose any one know if theze are the same axial setup as the armagedon dump trucks and do thay have the same issues.  

Re: JBC limited NZ
 

loader up and running again, I think I've dislodged the sound module cable,
will run a few more batteries and sort as well check diffs.


http://youtu.be/tJiVOInDKGA

Re: JBC limited NZ
 

put loader thru so rigorous testing ( just a bit of play time)
and all going well, battery flat again so the excavator needed a bit of a work out.
all going well.
don't know whats up with the mic on the lap top, I may adjust it with a hammer soon.

anyway heres a quick video of this mornings testing.

Re: JBC limited NZ
 

ok, finally got the signal reversing plug fitted, need to lower the revs a little but pretty happy how it works.

heres a quick video.
