Very interesting ideas there, Brady! Thanks for sharing them.

What size of a Gast Pump did you use? I too have the T-track and this looks great for smaller pieces.

FYI you don't need a vacuum pump unless the parts are very small. A good shopvac like a Fein or Festool works really well. They have a lot of CFM which makes up for porous or leaky setups as well. Small Gast type pumps require gasketing and don't hold MDF or other porous materials well.

I'm using a 1/3hp pump that I had for vacuum chuck work on my lathe and for vacuum bagging for veneer work. It's perfect for fixture work and pulls very nicely. It's not appropriate for larger work, however. Brady is absolutely correct that you can also use a quality shop vac for this kind of thing, but to clarify, you need one that has cooling capability that doesn't depend upon flow through the hose. Same goes for vac motors commonly available to "build your own".

There are tons of videos on YouTube about using vacuum and vacuum fixtures that you'll find helpful in planning your own setup.
