Having seen your previous work, I know that when it's all did & done, it'll be well crafted, & look amazing.

Re: Great Dane excavating co.
 

I should have guessed.

BIG DUMP TRUCK + BIG LOADER=LARGE MATERIAL OUTPUT 🍻

Re: Great Dane excavating co.
 

me thinks RW is getting serious about diggin out the barn & getting an INDOOR play area!

Re: Great Dane excavating co.
 

Thanks skeeter, and yes!! Have the perfect project for many years to come. Once I get the time I'm going to make an indoor screening plant. Large scale!! Well still scale to our equipment but want to move a lot of material. I have a lot of dirt that has been dumped for fill from rock raking /seeding yards. Perfect to haul into barn and then use the scale equipment to process. And best part I'll gain that wasted soil back. Might take a couple weeks to process a couple yards and then just a couple scoops with 1:1 equipment :). But it is an endless supply with a purpose. !!

Re: Great Dane excavating co.
 

That'll be great to see you fab that up Cooper... you build a Vario sized excavator & a couple cubes could be done in an afternoon. ;)

Re: Great Dane excavating co.
 

That payloader will move more material then any
Excavator could

Re: Great Dane excavating co.
 

That axle is looking good RW, looking forward to more updates!

Re: Great Dane excavating co.
 

Update,, still have some minor things to change but gettin the gist of it.

The drive shafts are long, they will be cut to size later

http://i1357.photobucket.com/albums/...psk5h4td8h.jpg

And I left enough material in relation to rims and hub to be removed if tires shrink more than anticipated from the mold process. That's kind of difficult to calculate precisely. (At least for my redneck engineering) ����

Re: Great Dane excavating co.
 

Oh and bearings will be farther onshaft for a retainer to keep them. I just don't want to pres them in yet. And I'm going to eliminate the chamfer between the two axle parts , I don't want that gap. Like I said still working on some fits and tweaks :)

Re: Great Dane excavating co.
 

Beautiful!

:popcorn: That software for your mill opened so many doors for you.

Re: Great Dane excavating co.
 

About how much machining time do you have in 1 axle? Your machining is outstanding!!

Re: Great Dane excavating co.
 

That is a hard question to answer, many parts,,, with wheels, probably around 12-13 hours? But I'm still learning and playing with numbers. Like the axle extension part that I.d. Of bearings slip over I had 1.5 hours in machine time. But now getting specs on insert and cutter I can probably drop that down to 45min. And another tool path I was using cutting speeds same as rapids and that took a 1hour program down to 30min. But I'm not breaking or pushing things:). Lots to learn for a simple mind like me:). And lots to improve speed up on. But I'm not trying to speed things up as in a production environment but just hate to see slow movements when tools are not engaged in a cut. :). And after the initial program was proven to do what intended. The bearing pockets were a few trial/error and sneaking up on proper clearences to get them a snug hand press fit. Wasn't using a boar tool just path and the tollarances on machine are pretty good. I'd say I get a good 80% score mark all way around bearing pockets. Good enough for me ;).

Steve (Ihbuilder) gave me the good idea of pressing on a piece of stainless for the bushing. Now the bushing material will slid against steel instead of aluminum. Thanks Steve:). The back axle oscillates something like ?? 10 degrees.

I still have to drill holes in axle. Wasn’t sure about how everything was going together at time. Still have a bit of the redneck engineering, build parts first then figure out how to fit them together :)!!!

Re: Great Dane excavating co.
 

And now working on the frame that pivots along with mounts for turning rams

http://i1357.photobucket.com/albums/...ps0ldvzazc.jpg

http://i1357.photobucket.com/albums/...pszkvdi75b.jpg

Building them to accept a tab and slot construction that will align and be welded together . On the 1:1 no hardware is visually in frame as they are cast and welded pieces. So I didn’t want any screws visually and welding is needed.

http://i1357.photobucket.com/albums/...psujhbzvb7.jpg

Still have to cut holes for the steering rams and bolt holes. These pieces required 6 different set-ups. Time consuming,,, as another said welcome to the machineing world :)

Re: Great Dane excavating co.
 

Wow :D There are several leagues in this hobby, and you are playing with the very best. Looking forward to more pictures.

The side extension supports[/QUOTE]

Me not being a machinist, how do you separate the milled supports from the base strip? Do they require another step to get to finished thickness?

Re: Great Dane excavating co.
 

This build is amazing.....and huge! Looking forward to seeing it in person one day. Think it will make Cabin Fever 2018?

Ken

Re: Great Dane excavating co.
 

Amazing work cooper!!! You are making good progress. Any idea how much aluminum (lbs.) you will use on this build?

Re: Great Dane excavating co.
 

Target is for before cabin fever, time to get any bugs worked out :).

And yes another opp to flip those parts and machine any leftover stock, some pieces can just be cut down, some need aluminum jaws cut to specific shape to hold parts while machineing. I will see if I can get a pic of what I did with them.

Not sure what final weight is gonna be, I know the tires alone are gonna be around 5lbs each. Heavy enough that I've had thoughts of ramps or rigging to load into vehicle 😛😛

Re: Great Dane excavating co.
 

Awesome work Cooper :cool:

Re: Great Dane excavating co.
 

Oh well I will watch and maybe learn a tiny fraction of what you know . Awesome

Re: Great Dane excavating co.
 

My first glance on the mounting bracket was; Will the bolts clear?
I see in this photo they do.


http://i1357.photobucket.com/albums/...ps7ieksv8o.jpg

Re: Great Dane excavating co.
 

Ken, these are the “soft jaws” I am referring to. The setup I have allows aluminum extrusions with a dovetail to be easily swapped out if the vise. Then these pieces of aluminum are the new vise jaws that can be machined to the shape of part. Basically custome workholding. First opp was to cut the parts out of plane stock. In the pic with many parts you can see. Then a set of jaws are machines to take those pieces and flip over allowing each piece to be clamped and held while machineing the original bottom side that is now the topside. And then another jaw was cut to hold parts in a vertical position to drill the hole for shaft. A lot of work but for multiple parts it’s a big savings.

And the jaw for the vertical position for drilling pin holes.

http://i1357.photobucket.com/albums/...psgxbaam4j.jpg

Learning all this stuff and all the processes machinests go through has made me realize why prices and time are the major factors in quotes for getting parts made. One part and a lot of set up time plus material costs then if multiple parts are done that price can be significantly reduce per part. So hats off to you guys that do this for a living and I will not complain (as much :) ) about costs of parts :). Hope this helps understanding ken, it’s taken me quite a while to understand these processes and I know I’m just at the tip of the iceberg!!

Re: Great Dane excavating co.
 

RW, thanks for the explanation. Wow, that is a lot of time and effort, but end result is great!.

Ken

Re: Great Dane excavating co.
 

Ah, so thats what you use them fancy blocks full of holes for . I'm always rummaging through the drops bucket .

8lbs 4 1/2 oz is what the front axle without tires weighting in at.

Re: Great Dane excavating co.
 

How wide is that front axle, outside of the rim to the other outside of the rim? I see it looks like you have a 12ish inch ruler laying by it, & it appears much longer then the ruler.

Re: Great Dane excavating co.
 

Skeeter, foto$&@“it isn’t playing well this morning, I tried taking a pic with measurements but it doesn’t want to upload the photo. In the other pics the ruler is a 6” stick. The overall from rim to rim is a little over 14”. Something like 14.3” if I remember correct. I’ll try later to get a photo to upload.

Re: Great Dane excavating co.
 

What, Photobutt's not playing well with others? :lol: That never happens :rolleyes:

This things going to be HUGE. I bet it will tip the scales at over 60 pounds, when you're finished with it. You're going to need a mini crane on your pick up, just to load/unload this thing.

After making some parts and fixtuering plate one of the front frame sides is close to done.

And beens how no one comes out to the garage I’ve been forced to have make believe friends and a lazy co-worker,,, i was all happy that this part came out fitting like a glove so I shared with the shop help,, he didn’t really care and gave me the one claw salute!!! Fat little b@@&$@d!!!

Re: Great Dane excavating co.
 

Wow looks amazing. Are some of those flat peaces lazer cut?

Re: Great Dane excavating co.
 

Beautiful work! Do you draw up all your plans before starting to cut metal or do you draw up individual parts as you get to them?

Re: Great Dane excavating co.
 

Thanks man, nope I’ve been cutting them on the mill. Wish I had access to a lazer !!! I did have to make a fixture plate so I could bolt down flat stuff. It’s not ground flat but way cheaper than buying one!! I use a piece of alum sheet under parts as a sacrificial buffer so I don’t cut fixture plate.

A picture of making the plate and then cutting the flat pieces. That one in the picture is the side of front frame from other picture earlier.

Re: Great Dane excavating co.
 

I’m new to this designing in the computer stuff, I know I should draw the entire model and then see how things fit, move, etc,,, but I’m still half backwards and just can’t wait!! So I draw up most of the parts/assembly and then cut things as I’m going. Probably gonna but me in the azz before long. Hard part is trying to think ahead of what needs to have holes or additions down the road. :). I’ve been using cad software for the designing and machineing stuff. Using autodesk fusion 360.

Re: Great Dane excavating co.
 

Kitty thinks you number one.

When doing that type of profiling , you could use plywood for your base plate or between your aluminum base plate and part since you aren't worried about the Z axis being all that critical. Then bolt it down using holes you have put in part or hold down clamps.
Use several so you can move them out of the way of the cutter as it advances then put them back as needed.
