Show us your home made tools

cheers fishy. just gota be careful to start in the groove. special tool 039 is internal spline counter, but still on drawing board. think got it sorted tho. watch this space. lol

I also noticed the lines produced on the tape that you had wrapped around the shaft. Even in the picture I can count 27 splines which is correct for a non lockup 904. Is that white lithium grease you used on it to produce the lines?
