Indicating & reaming throat under jaws/spider

[SKWERLZ]

What action is this for?

It’s going on a arc nucleus but that’s the tenon on the muzzle.

@X Count: I think I understand what you are describing but not sure. That setup won't articulate any more than a barrel being held by 4 brass inserts will it? Your chamber flush plumbing works great!!! Thank you.

It seems like the best solution to getting the chamber/bore/throat running true is the True Bore Alignment System. I have an inexpensive Grizzly lathe and if I thought my equipment was rigid enough to work with a TBAS, I'd order one but it seems like the inboard spider -- keeping the work pice as close to the headstock bearings as possible is the best approach for my situation.

The learning from this thread for me is to stop I holding the barrel directly over the freebore area.

Thanks,
Hank

Sorry I haven't used it in a barrel clamping / spider operation so cant say say how well it would work. That is just how I did the swivels on some extra heavy duty F clamps I made and just describing a complicated way of 'containing" a swivel foot but using machined parts.
