A Vacuum Plate can be a game changer if you have to make a lot of parts.
It holds parts down quickly for machining or clamping to your workbench. This version I designed is for your workbench and it is made from cheap MDF. If you have to sand a batch of parts this will come in very handy. I think you can also use this vacuum plate on your cnc router when using smaller tools.
Generating the vacuum is a whole other topic, I demonstrate that your shop vac can do it but I recommend you get a dedicated vacuum pump if you plan on using this type of work holding frequently.
