Slitting Saw Arbor/Holder

[Bob Korves]

I saw a very good way of assuring zero runout on a slitting saw on a mill. I believe it was posted by WreckWreck.

Mount the arbor in the mill. Mount a turning/facing lathe tool in the mill vise. Do a cleanup cut on the arbor deep enough to have a new support for the slitting saw. Face the end to length. Install the saw and go to work.

Interesting idea Bob but won’t that arbor now be specific to that mill? I wouldn’t do this to a nice commercial arbor, maybe a shop made?
Not poo pooing the technique. Just asking.

The tool gets cut each time it is installed. Only a few thousandths are necessary to clean it up each time. That approach takes spindle runout and arbor runout completely out of the equation (within reason.)

Yeah, It might come to that (cutting before every use) if necessary. I really don’t use the splitting that much, and would not think twice if I have to re-shape the tool for the round out.

O

looks good, But looks like that blade might be missing a couple of teeth.

O toothless one
