I have resently purchased a used CNC router. It consists of 4 7'x 8' tables. Each table is divided by a 1.5" steel tube. my plan is to install a vacuum system in the table (there wasn't one before) and divide it into 8
different sections so I can turn a section off if it is not needed. Having no idea of what this machine can do or how to run it my first part is to install this vacuum(or plan to install) From my little bit of research I figure that a 25 hp vacuum with at least 400 cfm can do the trick. However I must built weld a 1/8" steel plate to the underside of my table. My question is how far below the table top do I mount this piece of plate and do I need any deflectors for air flow or does it matter.
