Hey Tash, you and Blunted(Mr. 49V dragracer) are the highvoltage junkies at Hamdrl.

Bmaz, I'll see if I can make it Saturday and make a run with the pancar. Won't be as fast as yours ofcourse, but Tash's might be right behind yours(if his gears hold up).

sweet. more the merrier. I'm going to worry about my gears too. The problem I am having is that the motor shaft is mild steel. It isn't hardened and the set screw has a problem staying tight.

you can harden the shaft yourself by heating the shaft untill it glows red and quench it in 30wt motor oil it will now be hard but brittle, you can now reheat the metal to about 500 degs (tempering), there is now a battle between the metal being hard and brittle the more you have of one the more you will have of the other...I dont know how deep this penetrates the metal but at least the surface would be hardened
