Re: Dedicated MH Roller Replacement - Finished.

Well I m just working out the details of the costs now. Piece by piece
for the Vector list - A green Roller will be $10 (plus shipping) Would some one be willing to beta test a Green roller to see if it is and acceptable substitute in a stock MH controller? I don't think it it translucent enough to illuminate but My real drive for the project was for a replacement for the conversion kit. As of right now I don't even know if I can make it fit, but that's step two

Btw, I would want one of those repro rollers too. How much would you expect one to cost us? What are the magic numbers for changes in rates for quantities (with your machine shop)? I would guess this would be cheaper than each of us making one-off's.
