Re: Oshkosh Het M1070, M1000
Well classes are out till June, the only problem was that my HD was approaited by one of the students. Luck would have it that I backed up the drive last week. No cad drawings were lost.
Anyway, my friend Tyler came through for me on the air bags. Then I realized that I gave him the wrong measurement . So I had to do some modifications. First the product supplied was what I asked for to within 0.004" I took a trip to the local autozone, and was able to get an end section of hose material for the air bags. As I was compairing the assemblies with the 1:1 I noticed the slight bend in the bag assembly. I cut the new material a little long in case I need to shorten them later. Then I used a dremal fine burr to resize the inside. This worked out pretty good, as I was able to get the bend in the bag assembly. Next I mounted the bag to the frame mount, and support arm. I used a 2-56 threaded rod and a nylock on the top. The bottom was secured by threading a bracket that is mounted to the support arm. The best part is that it gives me a way to adjust the height of the axle. I am very happy with Tylers work, since I am a newbee. I can't understand why these bags are not on the other trucks on this great board. Heres the pics Had to add the referance pic Last edited by Car5858; 06-04-2011 at 04:26 PM. Reason: add referance pic sp |

Hey Carl those bags look right at home now on your project. Sorry you had to re make the bags themselves but they look great. Can't wait to see this chassis rollin.

Carl that thing is going to be such a beast. What axles are you going to be running on it?

I will have to shorten the axle shafts, byt its the challange in it. I will start making a pattern for casting the axle housings in the morning. Still don't know what to do for the front leaf springs. I want to stay close to scale, but may have to compramize. If I could find some blued 1/4" annealed spring steel, I would make them myself. I found some at McMaster Carr, that is 60$ I only need 32 inches worth. So if ya know a supplier that will supply short lengths, I am all ears. Took this beast up to the hospitle to show my Dad, he was impressed. (first time in 53 years) Now he wants out so he can turn the rims. |

Re: Oshkosh Het M1070, M1000
Thanks, to bad I never kept one of the wooden ones for myself. Maybe the next one, but the RC bug has bitten again and it may be a while.

Re: Oshkosh Het M1070, M1000
Carl,
I have been reading thru your thread and it is awesome, this truck is on my list of trucks to build once i get two others finished. What thickness aluminum are you using for your suspension brackets. I hope when I get the M26 done to start on one of these thank you for sharing. Merritt

Re: Oshkosh Het M1070, M1000
Merritt, the brackets and frame rails are 1/16" thick. Basiclly standard extruded alumnium cut to shape and finished with a file.
I am still learning about how to build them. So far so good, changed my mind about casting the axle housings(it would cost more that the truck itself). So now I am awaiting some flat stock alumnium. These axles are designed to use Tamiya's diff setup. Thanks for looking. Carl |

Re: Oshkosh Het M1070, M1000
Hey Carl have you thought about casting them yourself? http://www.lindsaybks.com/dgjp/djgbk/char/index.html

On your solid modeling; Is that done with Autocad or Solid Works? I hope I can do that kind of drawing someday. |

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) |

Re: Oshkosh Het M1070, M1000
Try your local lumber yard or plumbing supply house for banding, look around construction jobsites. The stuff is always laying around.
