Re: pic: Off Season Sheetmetal 6WD
1. Looks really really nice.
2. We have used .050 sheet metal with no lightening holes in the past with no issues (many of those robots lacked side bumpers, and are still fine). Have you looked at the weight difference of using a thinner sheet without lightening it?
3. Seems slow. Stock SS's are geared for 6" or 8" wheels, so with 4" wheels it will be a bit slow. You could re-gear the SS (modifying the last stage would probably be the easiest way to do it), or use 6" wheels.
4. Instead of the bolts holding the two sides together, you could use a sheet metal plate on the top and bottom. It might be lighter.
5. If the inside width of the two rails is about 2.5 inches, you can take an AM shifter and use the side rails as the side plates of the transmission.
