G'Day Folks,
I need to pick your collective brains again !
I switched to TBC rather than a mandrel a while back and am suffering from cracking of my blanks at the live centre end, not every one but enough to be very annoying.
I assume I am putting too much pressure on the tube and blank and hence forcing the ends to expand and crack.
One possible remedy may be too switch to a skew (less cutting pressure?) from my Pen Pro - what do you think ?
Another possible remedy would be to turn myself some bushing with 60 degree holes in to fit the centres.
Whats your experiences with this and how did you avoid/reduce this problem ?
This pen is a classic example, two cracks in the cap resin at the live centre end !
Regards,
Cam
