Re: Stiffest Drill Bits?

@Byiana - For building these cars, we are only drilling into wood, to make holes for the axles to go into. The idea of using stiff drill bits is to keep the bit from following the grain lines, going off the desired drill line.

All the better reason to use oil, my good man. ;)
Assuming it is allowed by the race rules, sure. However, unless it is an oil only race, they will invariably get fouled by graphite.

Re: BSA wheels

Derby Evolution posted a photo of the new wheels.

That looks like the best option yet. Not sure if mounting hole positions will line up with the bracket, but that is a minor issue.

Re: Need replacement switch for RaceMaster timer

MicroWizard Timers has an RS Remote Start Switch and 50' of cable for $15.00. My switch closely resembles the one shown by Vitamin K. They state if you are ordering this switch for a previously purchased timer give them a call and tell them exactly what you have. You will need to have MicroWizard b...

Re: Need replacement switch for RaceMaster timer

If the problem is a bad switch, then this part may be a suitable replacement, Omron D2MC01H. Though, it may be obsolete too.

Re: Need replacement switch for RaceMaster timer

@Anmarie - When you move the whisker, do you hear a click?

Check the wires connected to the switch and make sure that they are firmly connected.

Check also wires going into the back end of the plug on the end of that cable. See if you have a loose or broken wire there.

Re: Need replacement switch for RaceMaster timer

This looks to be the correct part, Cherry E53-00R, but it looks to be obsolete. Not sure what a suitable replacement would be.

Can it be colored or just tinted?
I've seen it both ways.
