Dreamed it up on the fly, working on blue prints. The chip conveyer is flat, enclosed in a tub that drains to the coolant tank. You can run flood coolant and the chip conveyer.
Normally I let the chips drain over night, start the conveyer in the morning. Lots of room for chips even if they build up. The belt support has a slight V in the center for the coolant
to drain of to the sides.
