Slitting Saw Arbor

This is a project that has been on the to do list for quite awhile now.  I’ve been needing a slitting saw setup since day one and have managed to put it off by using the bandsaw or hacksaw for most of my work.  It was time to make a proper slitting saw arbor.

Most of the “low end” slitting saw arbors you can buy are terrible.  The spring loaded ones that can utilize multiple arbor sizes are particularly bad.  I wanted a simple design for a 1″ diameter arbor size so I machined up one in less than an evening.  I utilized a 3/4″ straight shank so I could use it in the milling machine or lathe.  If you were running very thick saws, or horizontal milling cutters (not the greatest idea in a cantilever R8 setup?) you probably would want a keyway in the design in which case I would probably make the shank taper integral to the design.

But this one is for thin slitting saws and as such no keyway is required and being held in collet is my preferred setup.

There is nothing complicated about this at all.  But to save you some time sketching or drawing here are the drawings I used: Body – Rev 01 and Cap – Rev 01.  I didn’t add a flat on the arbor for removing and replacing the saws at the bench – I might do that at a later time if I find I need it.  If so I’ll update the drawings.
