simple qick change tool post

Post by elewayne » Tue Mar 24, 2020 12:50 pm

There is a simple tool post I've seen mentioned by some guys name. its just a square block with a round post through it and a height bolt, a slot in the side to mount a tool in. anybody know what that post is called? I saw drawings and sizes somewhere but I cant find it again now. i don't really need the drawings, but I'd like to see them again.

They’re called Norman style toolposts. There’s an old patent I think and many references to build plans/videos that you can hunt up.

This is the one I built but I didn't know it had predecessors. This one fits a 10/12 in Atlas/Craftsman lathe compound.

That drawing reminds me a bit of the Swiss made Tripan system Earlgo. Supposed to be as rigid as an Aloris or Dorian with the big advantage over them of having a lot more clearance when getting the tool post and holder in tight to the tail stock casting on our smaller lathes. http://anglo-swiss-tools.co.uk/tripan-tool-posts/ Yours should also do the same.

pete: This tool block clamps the 5/16" or smaller tool direct without any other complications. The slots are 1/2" wide and 3/8" deep but that is so one can put a clamp pad between the tool and the screw tips.
