Possible to simplify a design I don't split my brackets.



I drill the side hole first and put a bolt and nut thru and tighten it up, then bore the 43mm hole.
Lastly I cut the head off the bolt so the stud with cutaway can move and clamp.
Just like a tailstock barrel clamp.

Saves a slitting or sawing operation, did I mention I was idle ?

Not noticed mine getting hot but it's only the 800w model, never run more that 6mm cutters so couldn't see the reason to go bigger
