I taught in a metal workshop in another life. We had a metal cutting bandsaw as part of the workshop equipment. It had a small spout or nozzle located on a flexible arm (similar in appearance to a drill flexi drive) pointing to the table where the blade ran through the top and disappeared underneath. The flow of coolant (soluble oil + water= white cutting compound) was adjustable with a small in-line tap. The cutting compound was collected in a sump underneath and recirculated by a small submersible pump. The fluid would travel down past the blade ( just a bit more thatn a drizzle) A tray underneath shaped like a very wide /flat funnel had a plastic tube in the centre which directed the cutting compound into a square metal can with a submersible pump.
The metal cutting bandsaw also had a pair of brass stops or backing plates located behind and to each side of the blade to allow you to push metal onto the blade without the blade wandering.
From memory the bandsaw also had a butt welding joining device as part of the machine. This allowed rejoining of the blade after the many brakes that occur due to blade binding or simply suffering from metal fatigue.
You need some aluminium sheet, a low voltage pump , an in-line valve, a fluid nozzle and some brackets to fasten everything in place.
