Mini lathe internal dome tool

[tonyfoale]

Stevo,

here is an example of a yoke curve turning attachment.



Here is my not yoke interpretation:
Single piece, simple ball turner.

Thanks Tony for your link, I now know what a yoke is, no yoke haha. I'm still yet to come across any vids of the yoke system doing what I need that is doming the inside of my container lids. My tool can comfortably do 15mm radius up to about 60mm (if I dare) without hitting the chuck Jaws. I feel the yoke systems I've seen couldn't do this as well as what I've designed, best regards stevo

Stevo,

The yoke in the picture can do concave and convex. For concave you just swing the tool holder part out 180 deg. However, like you I am not over impressed by the yoke type. I think there are videos on the net showing concave machining but generally for making pipe bending formers not domes.

BTW. I will not be using my ball turner in the future. I have programmed convex and concave machining into my lathe conversion.
Screwing without screwing up.

Nowhere near as precise, but with a cool surface finish, we took an angle grinder and mounted it to the tool post "on edge". When we turned it on and moved in (slowly) it gave a beautiful radius grind with sweet swirly patterns. Not much in the way of adjustment besides wear, but cool and radius-y as well. I like yours better for the adjustability of it. Cool!
