Re: pic: Rastogi 8wd Iteration 1.2
I'm not an experienced sheet metal designer, but what CAD program is that in?

Re: pic: Rastogi 8wd Iteration 1.2
I would add in some triangulation in the x-y plane. Other than that I think it looks solid.
What material were you planning on making it out of? |

Sheet Metal is usually 5052, John or Art can confirm that (or anyone with sheet metal knowledge). 6061 just isn't that great for bending. Btw how much does this DT weigh? -RC |

KOP stuff is 5052 from AM (iirc), our other sheet metal parts were also 5052. 6061 likes to crack when it's bent parallel to the grain structure. I have also done sheet metal work with 3003 and 1100, which are very easy to bend, but weaker than 50xx aluminums.

5052 is the stuff for bending, as most of you have stated. Whatever sheet metal house is helping you guys out will tell you the same thing. -Brando |
Re: pic: Rastogi 8wd Iteration 1.2
Just a question: Is a sheet metal chassis lighter than an 8020 or 1/16 aluminum square tubing chassis?
Also, is there any sort of guide on building a sheet metal chassis? |

As for the tube chassis, I would think that a welded 1/16" aluminum tube chassis would probably be lighter as well as a bit easier to manufacture than a sheet metal frame. Sheet metal is nice if you have the resources and if you understand how to design to its strengths, but I dont see it as the miracle construction method that a lot of people on CD seem to see it as. |

For inexperienced and novice designers, chassis construction methods are far less important than actual design skills and features included.
You'll see crappy extuded tubing drives alongside crappy sheetmetal drives alongside great forms of both. Buuuuut, after a few years you come to realize nothing beats good 'ol 2x1:rolleyes: |
