Cutting aluminium without oil/coolant

The cheapest way to do it is to seal the MDF / paint it/ and on top of it use Expanded PVC sheet 5-10mm or even better use only paper filled or better type of phenolic sheet .

That sounds like a plan! I will have to wait a couple of months to afford it so will use an mdf board as a temp measure until then.

Next I need to buy 4 AM882's, a BOB & build a power supply, then upgrade the PC so I can run Fusion then finally I can afford the expanded PVC sheet (Or Phenolic) building a cheap ass router is expensive ha ha ha.

An idea I toyed with for a while is to take a small air tank (salvaged from a lorry) and put it in a cold water bath. Use a chiller to keep the water at 1C and then connect the tank to compressed air (With correct fitting of course) then I can charge the tank with compressed air cool the air down and then when uncompressed the air will be below freezing. Cooling the part whilst cutting it.

I would have to leave the air in the tank a good hour to cool down before using it so it's best to charge the tank then disconnect it from the main supply so it's not topping up with warm air.
