Special metal shaper
Is there any metal shapers that can do round shapes, like with "tilting" tool head? If there is, I need one.

A standard shaper with a dividing head, vertical rotary table, or other indexing fixture, will do that..
You just need a decent sized shaper to put them on..NorthernLight likes this. -

Both 6" and 12" P&W would tilt 5 degrees standard.

Yes, walked out into the shop to look at the both of them (a 6" and a 12") and the angle adjustment Originally Posted by johnoder

looked like mainly for clearance on dies sections.
If the O.P. needs more angle, suggest putting a tilting rotary table on TOP OF slotter table. -

Several (horizontal) American shapers, perhaps especially the American brand (which I think became the Cincinnati line) had auxilliary/optional toolhead arrangements whereby they could shape cylinders or bores or sections of same via manual feed. American also had an aux convex shaping attachment with power feed that mounted to the apron (standard table removed).
The tool head set ups included worm drive via hand crank to a gear behind the tool slide so the whole head could be rotated under positive control.
The convex set ups amounted to basically a tilting or horizontal rotab mounted flat to the apron (IOW, vertical orientation) with a gear adaptor from the table drive fed feeding into the drive for the rotab.
I've looked at a lot of shapers over 40 years and never seen one (either one), though.
Can you use a vertical rotary table or dividing head to do the work?

When the vid has finished, do a Youtube search on :- umf ruhla typ 32 , Part ll is more interesting. What a brilliant machine!, how did the design engineer come up with the multi-multi link mechanism!

This link is to a 1958 Popular Mechanics scan that shows some set-ups similar to what Stephen is describing.

I have a radius tool on my list of things to make for my 16" G&E, but more pressing jobs keep coming up. Maybe I can finally get it built this winter when things slow down. -

Curious operation - I tried slowing and stopping the motion, but am still not confident where exactly the cut is taking place?
Is this a job shop, or what industry do they make parts for?
If I could figure out exactly what was going on there, it may be possible to make a fairly simple accessory to mount on the table that is driven by a standard horizontal shaper. Some kind of rocking arm with an infeed toolslide.
