Slitting Saw Arbor..Precision..Near flush cut

[jjr2001]

I had this import slitting saw arbor but it had more runout than I liked. So off the the lathe.
I made this new one based on some ideas I found on the web including commercial ones.
It will approach the top of the vise by about 0.162" which betters my original by about 4 or 5 times.
I had cut the import down as much as I could but it was still too large.

I had seen one that simply made an arbor and them drilled the slitting saw for some flat head screws
which cuts flush. I may need to do one of that type some day but this works for now.

Using a 1.250" chunk of hot rolled mystery metal I made a new one that is a very close fit.
The retaining bolt is a 3/8-16 allen cap screw and so far it works quite well and gets up close.

Cheers, JR
