Testing shop made dovetail cutter

Very nice, Chuck!

You got my wheels turning.
Thanks.
 
Took me a few times reading your post on positioning the insert, but made perfect sense after I engaged my brain.

What are the inserts? Anything special?

The only thing special about them is that I had them on hand. I pretty much always use hss for turning so I've never gotten educated on insert nomenclature. They're triangular and they have about 11 degrees of clearance. I don't know what brand they are. Probably imports.

I have a lot of misc. Inserts. I had quite a few of the type I used. That's the only reason I used that particular insert. It seems to work. 20201220_123503.jpg
 
Now that I've done some test holders I decided to use a piece of bar and make 6 BXA holders. I generally make ppl projects out of scrap when I can. So I found a bar that was the appropriate size on my scrap pallet.

When I started milling it to square it up it became apparent that it was some kind of cast. It was either use it or saw a bigger chunk down to size, so I just went with it.

I cleaned up the four sides and then started cutting my groove.

With the groove cut I made my first pass on the dovetail.

While the milling was going on I started making the thumb wheels. I knurled some 1" 1018 bar and then mounted it in my sb 9A. I enjoy using the 9 because it's a machine that I got from a scrap yard. Somehow I get more satisfaction when I use it. Anyway, I needed to part off a bunch of wheels.

I guess I have hit my limit for pics on this post. I'll have to continue on another post.
 
So I knurled and parted off the wheels.

I intended to use the soft jaws I made to finish the thumb wheels....until I realized that I don't have that chuck anymore....and they don't fit the bison on the sb. So as usual I have a project to do so I can finish my project. So I have 5 big holders for large tools and enough stock to make six regular size holders. 20201220_165107.jpg
