Re: FD Roller, Material?, Method?
Something a bit disheartening happened. One of the 3 oak disks split along a grain just by the assembling process. I'll make another, and yes, I realize wood is unpredictable when it comes to strength along the grain lines.
I now think aluminum would be the best material. If I can get some thick sheet Al, I'll laminate them into a roller.
As long as the friction is sufficient to give the tire the ability to kill the engine by breaking, then it doesn't matter how abrasive the roller is to the tire.
