Here's an addy for McMaster-Carr. www.mcmaster.com.
They can supply lathe bits. Go for Carbide, it's really better than Diamond.
Pro Match batteries ROCK !!! I want to thank you folks for continuing to make stick packs available. Our club is Tamiya oriented and alot of the cars are set up for stick packs. Your cells allow us to teach the younger drivers about good batteries and they can actually use them too !! No more wasted money on cheapo packs that most shops sell for almost as much as your good stick packs. Thanks again.
