Default Oshkosh Het M1070, M1000

I started this build last week. Spent the last 6 months designing it in my free time. The first version was a wood replica, (avatar pic) some engine details and cab interior.

This is what the truck was designed from. I also found that blueprints.com is a good starting point for basic drawings. I searched the web and found Oshkosh site, some of their brochures have the specks for the truck and sometimes include an orthograph view of the truck. To bad they removed the Het that I am modeling from the site.

First things first, the design of the tractor is 22.5 inches long. This will be a 1/16 scale build due to having the tank for it already.

Been gathering parts, so far I have 2 tlt-1 axels for the front and rear steering. I have 2 intermediate axles, not happy with the width to wide with tires mounted.

My father has my lathe at his place and will be turning the hubs for me. I havent decided on the tires so far, I like the rockcrusher from rc4wd, but the OD is 3.55" ,y model calls for 3.3", I think it will be close.

I am planning on a Tamiya 3 spd and maybe an rc4wd 2speed as a transfer case.

I did get the frame put togather, and the tranny in position. Started on the cab yesterday. This is my first try at styrene, so I hope you are not as critical as I am myself. I have the floor positioned, then it was late and had to get ready for the school thing.

Great looking model! I think you have the skills to make an exceptional rc model M1000. If you can make one out of wood, plastic and metal should be no problem

I will be giving it a try, may take awhile as I learn new things and remember some things that I have forgotten.

Little bit of an up date, I started cutting material for the main cross members. Then had a resaw job come in that was a rush.

I did manage to get the rear suspension designed, Tyler will be making the bag assemblies for me, Thanks Tyler.

Here is the layout.

Carl it looks like you nailed that suspension geometry right away. Renderings look great and I am proud to have some products for you on your truck. It will look awesome when it all comes together. Can't wait to see some more progress on this beast.

Thanks Tyler, I have been in the shop playing with my drill press that I converted into a mill. Milled out the rear cross member. I will post a pic later.

I have to make the air bag mount next before I install the cross member.

Thanks Tyler, that will be great. I have 5 more mounts to make for the bags. I haven't started on the front supports so far. I will be back on the build this weekend.

Made some progress this afternoon, made the axle supports, changed the design a bit so I can mount the shocks inside the frame like the 1:1. I have the front support side frames started but not finished (need to bend them).

Its amazing what you can do with a bandsaw, drill press, and a set of good files.
here is the axle support.

Made a little more progress this afternoon.

I will be changing out the socket head cap screws for button heads. I need the scoket heads for the crossmember installation.

Attached the rear section frame mounts and axle supports. Used a .125 punch to help align the parts. Worked pretty good.

One thing I do not like is that the aluminum gets marked easily. I will have to disassemble everything and clean the parts up after everything is worked out.

Thanks for looking

That IS some nice hand work. I like it.
On your solid modeling; Is that done with Autocad or Solid Works? I hope I can do that kind of drawing someday.

Steve, I did solid the modeling with AutoCad 2009. First make an orthographic drawing of the part you want to model. Copy that drawing and start a new acad3d drawing, then paste the copied drawing into the new. This way you have all the elements in the proper view. Then you can use the extrude, press pull, subtract combine and 3d rotate commands to finish your shape.

You can get fancy by adding surface textures and rendering to get jpegs like I have posted.

Then use stlout on the command line to create an stl file for export to bobcad or othere gcode generator program that you have.

As for solidworks, I am not that proficent at it so far. (still Learning)

Progress is lookin good Carl. Your bags should be there shortly so you can have a rolling chassis. Can't wait to see them mounted up on this great frame. Should look right at home.

It will be awhile before I get a rolling chassis. I have to cast the axle housings and the tires. Still waiting on the rims, then I will have to make the drive axles. Not looking foward to that, I also ran out of 2-56 bolts today.

The good news is that exams are over and I get a break for 3 weeks before the next batch of students come in for summer classes.
