Radius/Ball turner build

Can you show a final picture of it mounted. I am trying to do the same thing and my lathe like yours has a post under the cross feed. I still don't see how you are holding it down. Really like it so far.

Got it mounted and able to demonstrate how it works but not quite useable yet. I need to get the carbide insert I'm gonna use so I can cut the tool post to proper height and make my handle which I may do later tonight. You can see in the pictures how I made my hold down for it.

Looking real nice ;)
Your so close to finished product, it must be killin you waiting for the insert.
Are you going to make up the handle with the ball as one piece, or separate items?
That tool would look nice with a one piece tapered handle, with the ball done with your new tool.

Looking great, keep us updated Charley, the Vids are great too.
 
Charley, the ball turner is very impressive! Can't wait to see the finished product. Philco.
 
Last piece to the puzzle

Benny brought me some carbide inserts but quickly pointed out an issue with them hanging too far over the edge. So I revised my plans and decided to use HSS 1/4X1/4 cutter tool stock. I milled out some of it on my Burke but the head seized up after about a half hour of use, gotta check into that now. So I took it to where I used to work and finished it on the Trak. I'll grind the cutter tonight and try it out, video to shortly follow that.

Here's the finished project (not really, I have some revisions to make) The hold downs need some help so I'm adding 2 more & a little broader & placing them in the 12:00 & 6:00 positions. I may have to drill the axis hole out bigger and put in a bushing as it has a little slop in it. Also in the "T" slot I drilled and tapped the hole where it falls centered on the top edge of the shoulder, need to remedy that also.

As you can see in the second picture the loosness of the hold downs really is an issue:mad::thinking:

Charley, thanks for the video, well done. There is definitely a difference in the stability of the cutter between cutting convex and concave. I thought that the ball on the end was doing very well where there is short over hang, the issues start on the concave portion of the handle. Good job, and there is for sure some experience gained for all who watched.
Thanks again,
Bob

Thanks Bob, I think I have a fix for it. I need to get more tooling for my mill I don't have any cutters at all for the horizontal and only a couple good cutters for the verticle head. I kinda crashed after seeing you today, I worked in my shop till 3:30am and didn't sleep well then got up at 7:30am. I may work on it later tonight.
