I just made a tool post with a straight turn instead of the D shape as his. It works real good. No need for the triangular shaped tool holders mine are square and can have tools sticking out of 3 sides. I didn't incorpurate a height adjustment in the holders , but all I have to do is drill and tap for an adjustment screw. I made mine for a 3/8 tool and I use 1/4 tools with a 1/8 shim under them. I got the plans off this site somewhere? All made on my 9" South Bend. Boot

Bob,

Glad to hear you like it and are trying it. If you have any questions or problems, I am here. Please do let me know how it turns out.


Boot,

A round post would surely work and others have done this. But it does not provide the re-indexing that the D shape does. With that plus the height adjustment screw, you get repeatable positioning well within a thousanth when you remove and replace the holder.

I have also used 1/4" tools in mine and the adjustment screw eliminates the need for shims.
