Sorry for the late reply I have been away. Yes I have considered making a QC post myself but I was unsure of what design suited my lathe or me etc. Not ever having one before.
However I see what you have made and it is different from the ones I have looked at.
It is very simple as far as I can tell . No piston or wedge sytem . Just a slot cut to allow the dovetail to clamp. Have I got that correct. It looks like a real good idea for a home made unit . I will look at the site you mention and see if I think I can make it .
What degree and diameter dovetail cutter should I buy?
Thanks for the help and the great photos.
I will get back to you .
We should start " The AL 1000 area " without the serial number registration stuff .
After looking at the Groz system I can see that its not a slot but the clamping side is cut right off and it pivots on a rod.
