I used a Miro 22-quart aluminum pressure cooker, and a Robinair 15300 vacuum pump. Both were available from Amazon and reasonably priced, but there are plenty of other sources for each. That particular pump comes with 3/8" and 1/4" Flare fittings on the inlet port, which is why I needed a compression-to-flare adapter. If your pump has different fittings, you'll need to use the appropriate adapter.
For the 3/4" drill bit, I used a low-end black oxide bit from the local hardware store. This isn't the best choice for this application, but it's all they had, and I only needed it to work once.
All of the fittings are standard 1/4" NPT brass fittings. I found them at a local supply store, but they're generally available online for about the same prices. I used a cross-fitting as the central fitting in this setup so I would have an extra port for future use. You can just as easily replace the cross with another T-fitting, and use one less ball valve, to save a little money. Fewer fittings means less leakage, and better vacuums, so feel free to remove anything you don't need.
