**95% success on this one… Didn’t allow for the kerf in places** Excess water splashing was intentional to keep the heat down. Worked well too.

What is the elevation distance from the bottom of material being cut to the surface of the water below?

A reasonable guess would be around 50-70mm or 2"-3" - the slats are 25mm / 1" - the 70 PSI from the torch is the main agitator

Thank you for the reply. I am about to build my own Arc Droid cutting table have to determine what elevation to locate my water pan.

I don’t think it matters too much, anything up to say 5" below the slats would cause splashing just make the tray 3 to 5" tall and then mount it 1/4" under the slats and you will be good.

The splashing helps with the smoke a bit but also keeps the work cool - The “smoke” in my video is actually steam. I could pick up the saw blade straight away after it was cut as it was only warm not hot - zero warping from all that heat input
