Not hard or expensive to make small vacuum system if you use a Pod system and don't cut thru. I've got one here that use's a fridge compressor and I've held and engraved brass with it.
So long as your not cutting thru then it holds full vacuum no problem and it won't let go if the material isn't pourus. Attach compressor to a Tank and pull tank down to vacuum and it will hold part without pump running provided you have a good seal that doesn't leak.

You only need lots of vacuum volume if you don't have a good seal or material pourus or your cutting thru. Normal vacuum machine into larger chamber with a small output pipe to a pod would work provided chamber didn't leak and had enough volume to pull part down to full vac and hold before vacuum drops to low. Try it I think you'll be surprised just how well a normal vac pulls down.!
