Dry Aluminium Cutting Problem

[Robin Hewitt]

Could I ask people to post up or link details of their coolant set-ups to give me inspiration?

Here's a pretty one I made for home use, had to pass wifely inspection.

One of those aluminium boxes with the O ring seal to make it weather proof. The lid is bolted to the end of the bed with a hole to drain the suds back in to the tank and type blue gasket compund so it doesn't drip.

In the bottom of the tank is a fibrous mat designed for filtering Koi carp pond water under a mesh to keep it in place. The oil goes down through that into a coffee machine pump I got on ebay. Spare pump on top of the tank. Then a hose to a magnetic nozzle.

I put it all together, switched on and found the pump was MUCH too powerful. Hence the knob at the back of the tank which allows most of the suds straight back into the tank.
