Indeed Pix, the position of the broach tip's critical, the run of the mill tailstock or turret mounted holders dont have any adjustment and so have to use bits of one.specific length for their geometry to work. It occurred to me that a QCTPmounted broach holder would allow easy adjustments to put the bit in the righ place.
I can appreciate that a lot of lathes wouldn't have enough force from the carriage feed though, particularly with larger broaches.
If anyone knows of a table of broaching force for different sizes and materials, a link would be useful!
