Re: Oshkosh Het M1070, M1000
Made the molds using mold putty, came out acceptable. Tried casting with JB Weld, and suprise I have some parts. The parts will clean up with a file and sand paper.
If I have some parts prototyped again I will raise the resoulation. These parts were set on the lowest resoulation for rendering. Although the resoulation does not show in the rendering photo, it will show up in the printed part. |

Re: Oshkosh Het M1070, M1000
I have to agree Russ, this is what they look like cleaned up. To bad it takes 30 hours to harden before you can file and sand them.
I also tried smoothing out the molds, maybe that will help with finishing on the next one. I also rotated the pinion mount 22.5 degrees so that the hardware will have more material for threading. I also attached the swivel connectors. Just a few steps along, classes start in the morning so I will not be able to work on this much during the week for the next two months. |

Re: Oshkosh Het M1070, M1000
Parts turned out great! Excellent detail and overall look is so real. Combination of high-tech (3D printer), low-tech (JB Weld), generous supply of imagination and great workmanship, and we get to see top-level modelling. Well done!
Ken

Re: Oshkosh Het M1070, M1000
Thanks for the kind words Ken.
I got a package in the mail the other day, RC4WD Dirt grabber tires. Still waiting on the rims. My Dad is out of the hospital and is starting on the rims in the morning (weather permitting). Hopefully in a few days I will have some more photos to post. |

Re: Oshkosh Het M1070, M1000
The Stamped rims came in from RC4WD today (one bolt missing). Yes I could not resist the desire to see some tires and rims on this thing.
Mounted the tires on rims, there must be a secret to this part that I haven't figured out so far. The tires wobble slightly side to side as they roll, but not the rims. As for the rest of the covers I am waiting on more JB weld to arrive. I did find out the hard way about mixing. Not enough hardner and the cover is to soft and flexiable . Oh well, I will start again in the morning. |

Re: Oshkosh Het M1070, M1000
Thanks Rob, currently I am awaiting some more parts that I haven't been able to spend time on this for the last week.
Will get more updates when the parts are finished. Thanks for looking and the encouragement. |

Re: Oshkosh Het M1070, M1000
Sample rim came in yesterday, so I set up the rotary table and was going to install the dividing plate. Not the right reduction, this table has a 1:46 reduction cant use the dividing plate. Looked around the net for a 1:46 reduction chart no one seem to have one.
So as an alternative, I wrapped a 1/4 inch wide strip of paper around the rotary table to get the exact circumference, I then drew this up in AutoCAD and divided the legnth by ten with the divide command. Perfect, added an extra 1/2 inch to the length, plotted and attached to the rotary table. This is the result, the bolts are 2/56 socket head cap screws. I did miss one hole by 1/2 a degree but it is not that noticeable. So far I am happy. After assembling I found that I have to change the design of the inner hub to allow the locknut to seat properly. At least I have made some progress. Thanks for looking Carl |

Re: Oshkosh Het M1070, M1000
Thanks Steve
Took the rim back to my dads and he was shocked that he missed the dimension. He had started on another rim, so the mod will have to wait till he gets the next one done. Luckily Dad only lives 3 blocks away. |
