I forgot to post pics of the finished door on the 1500x1000 machine, so here it is.
This giant vertically sliding door is counter weighted with a couple garage door springs so I can lift it with one hand. it locks in place with a single bolt. I’ve also recently mounted my Festool dust collector inside the box, and routed the hoses through the top to a Dust Deputy attached to a 20 gallon yellow tub.
This weird arrangement was necessary because the room is only 10’x12’ and I have another large workbench off to the right in these photos, so there’s no room for swinging doors. This seemed like the simplest solution. It’s largely MacGyvered together, but at least it’s functional.
