Air flow

You don't necessarily need a lot of pressure, it's the air quantity and velocity coming out of the nozzle that counts. Hence if you have thin pipes and a small nozzle you'll need higher pressure. I have a little side channel blower on my setup which only makes about 6 or 7 PSI but is much quieter than most compressors and outputs a lot of air and does the job fine. As per Cropwell I do find that some water/lubricant (I use 7....10% soluble oil in water) is a big help in stopping the ali sticking to the cutters.

thanks I will see what I can rig up.
