Re: Wheel to Wood Friction

Hub to wood touching can be eliminated where "hubcaps" are allowed.

See my post on that topic for how we avoid the wood contact issue.

I'd love some comments on this by some of you awsome gurus.

This is a great resource btw.

Re: Raingutter Regatta Track Designs

I used PVC rain gutters for ours. They have straight sides on the top 2or 3 inches. I used the standard caps but drilled one end of each and mounted a pvc valve for draining into a bucket at the end of the race. For supports I made 5 brackets of 1/4 inch plywood that were cut to accept two gutters s...

Re: Hubcaps

For what it's worth.... We looked for custom wheel web sites (for real cars) and captured a jpg of the wheel of choice. Puting the image into a Word doc and sizing the page on the screen to actual size allowed us to re-size the image to the correct scale for the derby wheels. Once printed on a color...

Re: Mini, i.e. affordable, hobby lathe?

I also use the Dremel. I mount the flex shaft thing in a bench vice for axel work and sand the wheels in it too using a mandrel. You must wet sand in the dremel because heat build-up will melt the wheels. Looks like a neat little tool but I doubt it would have the torque needed for turning the block...

Wheel weight

I just discovered this forum today, 2 days before our PWD race. I've seen that the general opinion is that lighter is better but couln't find any discussion on weighted wheels. Could it be, that whells filled with, say, hot glue whould have a flywheel-like affect and help carry the car on the flat o...
