...all those work. Be careful, porous sheets (like MDF and cellulose) will often pick up 1, 2 or 3 sheets at a time.

Melanime and plywood, respectively in the videos are fairly NON porous and will grab only 1 sheet at a time.

....for what it's worth.

Sean I think Pmk was talking about the front loader found here http://www.woodmotion.com/front_loader.php

No vacuum just mechanical lift.

Adding another video of a DIY version.

anyone know if a vacumm pump like this will be enough. with a small tank.
like 120 -200 liters per minute depends on the model.http://www.processvacuum.co.za/vacuu...tem-vacuum.jpg

Nope this is not even close. This is a low flow high vacuum type. you need at least medium flow type to compensate for the vacuum lost through mdf porosity & other leakages.

It does sound like he is using a Venturi and some kind of Air driven drive to lift the sheets. Both should be availible for much cheaper than the pump.
