we seal some of our products with SMD Sunflash resin, an industrial liner (for heat protection and re-texture after milling) and a final blast of SEM Chipguard. I do a lot of spraying in the shop. I needed a way to evacuate the fumes so about 2 years ago i made a downdraft table. The suction is supplied by a large shop vac that was purchased JUST for this job. It actually does a good job of sending the fumes out if its 25’ of exhaust tube aimed out the shop door. ? After 2 years of use it was time to replace. So here is the new 2 i made today. These holes are all very strategic and not JUST vents. It also protects the hardware from over spray. We make fuse blocks in single, doubles, quads, octos, deca’s and even a 16 slot ANL. An entire separate XL series line up also. This means we have a lot of combos and a LOT of holes to drill.
this Deca (10 spot) has no sealant on the back yet but i am testing it for fit. Again, these holes all mean something. They are not just random
