Parting Off Tool Made From 1/64" Slitting Saw

I made this when I run into a problem parting off some small diameter washers my normal 1/16 parting tool was too wide it just bent the bar. It's not my original idea I saw it some ware can't remember ware.

It easy to make and when one tooth gets blunts you just index round to the next.

Stew... That's very ingenious! I'll be making one of these soon. I like the fact that you don't waste as much material than you use. What's the diameter of the slitting saw that you use?

idea pinched.

cheers for sharing.

Hi John

It's diameter is 1 3/4"

Thanks for your interest

How surprising. I made exactly the same type of tool, but for cutting 1/32" slots in 3/16" silver steel for 'E' clips for the valve gear of my PANSY.

Cunning I will be making one got lots of slitting saw blades

Made one years ago from pieces of broken blade - got the idea from ME Mag in about 1960 ish

Think I saw it in "Popular Mechanics" many years ago.

A cheap source of thin parting blades is the snap-off blades used in craft knives. One section broken off and the top part honed on a fine diamond hone, then the section mounted in a holder. The shape of a snapped off section provides all the right angles. Works well on plastic and aluminium, but have not tried it on steel, although I don't see why it would not be suitable.

Doug,

That's an excellent suggestion.

In the interest of safety: May I just emphasise one point that you made

... "One section broken off"

Note: If you need a longer piece, don't be tempted to use two sections, go to the back end of the blade instead, and use the stub.

P.S. ... Genuine Olfa blades seem to be much better quality than the others.
