Radius turning fixture?

[OldCarGuy]

My lathe has a single 3/4-10 bolt that runs from the compound T-nut through the tool post. I wanted to make a radius picture that can go on using the same T nut and this is what I came up with. Probably won't be able to finish it for a while but I think it looks cooler than most of the ones I've seen so far. I'm just not sure if I'll be able to secure it to the T nut and if so, how secure the dovetail will be. Anyone do anything similar?View attachment 500126View attachment 500127View attachment 500130

Great thinking and cleaver delivery. Exceptional idea using the taper bearing...

I came across these old Monarch tools 30 years ago at an auction..
For convex radii

Concave radii..
