The secret of succesfull vac clamping is SURFACE AREA! double the surface area = double the clamping force. My biggest enemy with vac clamping on Ali plate is that the plate slips due to the force of the cutter on the work. On a job i did recently on 13 x 9 x 1" plates i was roughing a 1" doc x 1/3" at 30ipm no problems. I had to insert 2 pins to locate the plates and keep them frim slipping. the vac supplied all the down force i needed. I make a lot of parts fom 1/4" ali plate and i just gang them all together on a big sheet. I then cut and drill them 90% depth and use the bandsaw to seperate them. I then run the holes through on the pedestal drill and use a flushtrim bit on the table mounted router to clean off the other 10%.
Works for me and saves a lot of setup time.

I am going to use 3/4" MDF fly cut about 1/16 " of both sides to expose the core over a grooved plenum and use a roots type positive displacement pump (ebay) with a 16 hp elec start gas engine mounted outside my shop in an enclosure....bada bing.
