I have used their lids on any win-co aluminum pots. It is interchangeable from 1g, 3g, 5g.

Make yourself one!!
If I can do it anybody can..
Find a thick walled Stainless steel vessel (Aluminum is more likely to crumple)
Drill a pilot hole about 2.5” below the rim of the chamber for a bulkhead fitting, secure with a washer.
Teflon tape all threading.insert a hose barb.
You will need 2 NPT 1/4” ball valves and an NPT T.
One ball valve is used to isolate the chamber from the pump to prevent pump oil from back-flowing into your chamber, the other is used to allow air back into the chamber.
The lid is the most costly part of the DIY chamber.
Ideally, you want a minimum of 1” of polycarbonate.
I am having success with my lid however, and I made it for 12$..
I bought a bunch of standard pieces of 1/4” acrylic lexan,4 pieces made 1”.
I drilled holes in the sheets all along the corners and edges and bolted them together with a lock washer.
I have a slight defection in the lid, but is holding up well.

Lmao!!
Knucklehead = Bulkhead
Obviously, I'm a stoner. Not a craftsman.
Haha
Edit edited the correct terminology, as to not be a knucklehead

I like the idea of popping a 4 way crossover on a pressure cooker lid (where pressure valve normally goes.) Put a gauge on top, release valve on one side and vacuum port on other side.

Good points! You can also add an inlet filter to the release valve, so as to filter all incoming makeup air.
