Hi I'm looking to build ASMBL substrative tool from @Greg Holloway About C8-ER8 100L Collet Chuck, when I check the link : https://www.ebay.co.uk/sch/i.html?_....l1313&_nkw=C8-ER8+100L+Collet+Chuck&_sacat=0 I can see several version : C8 ER8A 100L C8 ER8M 100L Which one is the good for this Greg substractive tool ? Thanks ! Sylvain
Hey, Version A has a hex-shaped clamping nut. Version M requires a splined-wrench to tighten. I think either one would work because they can probably be tightened sufficiently by hand (i have version M and haven't had to use the wrench, but do what you are most comfortable with.) You will also need an ER8 spring collet that will fit your tool shank size.
