Bionic Balls Posted January 28, 2005 Report Share Posted January 28, 2005 Does anyone know the pitch on (drive side) a pedal thread (and any other information about the thread if you know it!). A mate has stripped the thread in his crank but his dad is an engineer and is making an insert (bit like the tensile one) to replace it. Only thing is- he can't work out what the pitch of the thread is.. cheers, adam Quote Link to comment Share on other sites More sharing options...

Bionic Balls Posted January 28, 2005 Author Report Share Posted January 28, 2005 he's tried alot of taps...if he can't find the standard tap to fit, he's going to have to measure the pitch and screw-cut it on the lathe. adam Quote Link to comment Share on other sites More sharing options...
