Hi Felix - welcome to HomemadeTools.net

Sounds like you are having fun

What tools would you like to make next? Here are some ideas from last week's builds:

Tracked Mini Dumper
Rotary Tool Vise Holder
Big Wheel Torch Cart

We're unaware the volume of vacuum you need to pull down.

• But if it is more or less like size of knife parts, vacuum generates easy with a standard compressor.
• Connect the box plate to a venturi ...... https://www.google.com/search?q=vacu...utf-8&oe=utf-8 upstream from your compressor.
• Adding a reservoir tank will help if compressor is small. Unless you are involved with high production numbers buying a real vacuum pump won't make you very happy. $$$$
• A shop vac will also produce vacuum if you add a globe valve to let the vacuum breathe, tee'd into box plate. Wide open is lowest potential draw down, fully closed starves the shop vac and will over heat.
• You can nest parts with small pins, or set part in close fitting pocket.
• There are right-hand cutters with left-hand helix that won't pull parts up like a drill or an endmill can.
• There's all kind of vacuum hold down tricks.

I betting if you post a description, drawings or photos what you want to do, beau coup responses will occur from the collective sites.
