Just need some steel mesh for the catch pan.

Why?
Take a neodymium magnet, stick it in a thick ziploc-type bag, and place it in front of the overflow for the pan.
VERY nice job with the braided hoses and fittings. WIsh I hadn't seen it, now I gotta upgrade...
Couple questions...using steel screws for the muzzle fitting isn't damaging the barrel? And which part is the rotary union? Looks like all compression fittings to my novice eye...

Yes. All re usable fittings. I have magnets in the pan. Was just going to put a screen on top to catch the larger pieces.
The screws i made with brass tips.
I also have made adapters to thread onto muzzle brake threads. And the other and a #6. Jic fitting.
After i see what improvements it needs i will likely bend out some custom catch pans.
The rotary union is from a pressure washer

That rotary may not be up to the speed of the lathe. If it fails it will make a mess.

a yuuuge mess waiting with that coupler.

I watch eBay for good buys on rotary unions.

Well the coupler was all i could get. Its better than an air line couplers. I do have an actual rotary union on order.

Keep in mind also that as pictured, there's no adaptability for barrels of different lengths.
When you change out the union, consider making up a longer length of hose (assuming it's quite flexible) that'll reach to a barrel at the end of the spider. I'd use 90 degree fittings at both ends leaving a "loop" of hose that'll be infinitely adjustable to any barrel length. JMO.

Good luck.

Pro Tip: If you hook your 120 volt pump up to 240 volts, it doesn't last very long.

No need to ask me how I know

The whole arm slides. The barrel in there was 34 inches. And the arm will slide all the way up for a 22 inch barrel.
