Yup, same thing, bit the bullet and bought one of those models, scaled off of it. Also various pics, company brochure , and shop manuals. Pics from Mario will help. (Would be nice if cat would give me access to detailed manufactuering blueprint) blahhhhahahah

Hey Cooper/Cat

Have you looked at this : http://www.the-blueprints.com/vector..._mining_truck/

You R doing AWESOME work Carry on

[steamer]

R W you might want to take a look here too. On page 17 there's a three view drawing of your truck. Load it on a zip drive and take it to your local copy center and have it enlarged so the axle wheel base is 14.571 and you'll have a drawing you can measure strait off of.
Good luck, she's going to be big!!! 32.5 L x 16" H x 19" W

Thanks bo, and steamer, they will help!!

Well I wasn't sure about power of the gearhead motors I got, so I got some new ones in mail, they are .55horsepower each. They should move it fully loaded. But on the serious side, this thing may be pretty heavy, tires are 4 pounds each, that's 24 pounds just in the tires!! I really don't know what weight she will be but it's probably gonna come in around or over 80 pounds. I'm planing on frame and most structural stuff alum, the dump bed sheet steel. I hope my brazing skill will improve. I really don't want to have a bunch of ugly tack welds on dump box necause it will be pretty visible when raised.
Steve, thanks for the kaydon bearings, they are the slim type I was looking for, but,,,,, those little suckers are $100 or more for one!! Changed my ideas around on the axles to suit more practice bearings. I have almost 6" between rear tires and duel wheels spread almost 5" so plenty of room to hide motors/support bearings and anything else in rear axle. I also thought about 1:5 and 1:8 scale gas RC trucks rear differentials but I'm thinking they are even small for this!! And the gearhead motors I am getting have a 1/2" shaft, 1 1/2" long. Keyed and end hole tapped on shaft. That will make a really solid set up for removing load from motor shaft to the truck axle.

This thing is going to be almost 3' long, 18" wide and with dump bed raised almost 32" tall. This may be on the limits of what I can comfortably carry around. !!!! One thing about this is it is a fast mover compared to the dozer, as long as it's is running I'll be using it to move me possibly!!!! I'm just guessing here but I imagine it should be able to haul about a five gallon bucket of material. Should be built to support 80 pound load or more.

glad to see it all coming together brother, cant wait to see this bad boy i action!

[Supermario]

And don't forget the battery weight and size. Probably going to need a good sized one for decent run time. Or maybe wire up a whole bunch of those lipos you got should work.

I'd hate to see you strain your back carrying the beast. Better build a tow cart or something for behind the ATV?

[Bo Wallen]

Hey Cooper !

This might avoid future BackPain Just train Mr Nutter to drive The RockBeast and the transportation is solved. Roll on roll off :https://www.youtube.com/watch?v=OPdCDj_RiKI

[Cooper]

Good idea Bo, but mr nutters has moved onto another worksite, he now works for the forestry department.

Well I know I got the pigment right this time. And I mixed for 1 min, immediately poured and had the mold slightly unlevel, tapped mold, basically did everything I could to eliminate the air. Time will tell, about two hours and I get to see if hero or zero!!!

[Bo Wallen]

Drumroll, Please !

[Cooper]

Here ya go mark,Bo,, and some scale along the aeromax

[Bo Wallen]

[Mikem]

Impressive cooper . I think you'll be able to put all my trains in the box ! Mike

[RCP57]
