Looks intriguing; the presumption, then, is that somewhere in the world
is a rolling mill turning out pentagonal bars? And mill vise jaws with
108 degree and 36 degree vees?

The pentagonal spud on a fire hydrant cap/valve is the only item I can easily
imagine this chuck holding.

It might be useful to make a model 5 cylinder radial engine.

I just bought their (last?) 5" 4-jaw for the BS-0 index, for $88.79.
The plan is to fit it to both the index's blank backplate and a used
5C pot collet to mount on my lathe and another less bulky 24-position
5C indexer.

Just like a 3 jaw it is also VERY good at holding cylendrical
objects - very commonly used in a lathe for "turning" - - - - -
Grips better than 3 jaws and distributes the clamping force for
hollow workpieces.

They seem to be more common - if you can call it that - on
wood-turning lathes. 6 jaw is more common withthe same advantages if
NOT chucking penta stock.
