Step 13Time for a Body
The built of the body went so fast that I forgot to snap photos during the process! I did do a quick concept drawing and I've also added a good picture of the finished sander.
The second photo was taken by a spectator at the moment the sander accidentally launched off the end of the track. One good thing about this view is you can get a good look at the rollers that keep it centered on the track.
On that note, several sanders at the BSRA race at the AWFS show simply ran their sanders down the track with only drive train modifications. Their sanders may have been fast, but they bounced from one side of the track to the other the entire length of the race, losing momentum with every bump. The rollers I used are sliding door wheels like those found in any hardware store and were quickly screwed to the bottom of the body.
One final note on the body. I debated the idea of centering the sander in the body, but decided to mount it as far back as I could. This would add weight on the front end which I hoped would keep the sander from popping a wheelie. You can see from the photo that I removed so much of the body to accommodate the handle that I actually had to add a rear "bumper" made from a decorative cabinet door handle to keep the body together.
I added another of these handles on the front of the body, and it's a good thing too, because this bumper really "bumped" when my sander rolled off the track on one of the first runs! Yes, this sander was so fast that it left the track on two runs!
The front bumper tore off on the first impact with the floor, so in the airborne photo you can see an on-the-fly mod with a couple strips of duct tape.
More on that in the last step.
