Modified Knurling Tool Holder

[kquiggle]

When using a scissors type knurling tool on my 7x10 lathe, a problem I always seem to have is that the tool wants to twist sideways. This happens no matter how much I tighten down the tool post and compound slide. So I decided to make an adapter to hold the tool in the center of the tool post. If you are having a similar problem, you may find this useful.

The photo below shows the modified tool in action. It seems to have solved the problem, and as a bonus, setup is much easier.

That's a very clever idea!

Thanks Rob. - It was surprisingly easy to make (especially since I already had a "blank" dovetail tool holder for my QCTP). It occurs to me now that the adapter and tool holder could probably be made all in one piece and would be a bit more compact. I didn't think of that before becasue I already had the dovetail part; also, I don't have a piece of steel on hand large enough for a one-piece version. Always more than one way to skin a cat.

One thing I should have mentioned to anyone who wants to try this: Check ahead of time to make sure you can back off your compound slide enough for the tool to fit.

I've been using the modified tool quite a bit in the last few days and I am really happy with the results I am getting.
