Nice mill. Looks like a variable speed head too! Very nice. Don't worry, my mill table is just as crowded with stuff that needed somewhere to put down mid project. Why I refuse to get a cart as it would just make matters worse.
Yes variable speed, and DRO (digital read out) which is very handy. I keep mine zeroed at the front right corner of the back jaw of the vise. Mostly I use it to find the center of work clamped in the vise. This year I did build some wooden covers for unused portions of the bed, they are barely visible to the left and right of the vise. You can lay tools down without fear of denting the table top. I made three six inches wide each to I can position them adjacent to work. I need a few more.
Did somebody mention JATO?

Yes, I have witnessed a C-130 take off with it once. Pilots were doing a assisted take-off training exercise. I was only 6 years old but not something I will ever forget.
Read that somewhere about the a-10's being marked for decom prior to the Gulf war. Not surprised they didn't, given the gap it would leave in their capability. Can imagine a small squadron of them coming in NOE at low speed. Each dropping just over 7tons of ordinance. That's why most often they only ever needed one or two per sortie.
I know what you mean. Saw both SAAF Mirage F1 and Atlas Cheetah at air shows in SA do a fly-by, turning on their afterburners as they went over, ripping past for a bit of extra effect and feeling the hot exhaust at that distance. Would be something else with the proximity on board an aircraft carrier.
What about a sliding gate closure(le guillotine) between the louvers and the extraction fan? Dead simple and easy enough to operate outside the plenum too.
Now there's a great idea! I'll slide right into that idea
Man, I wish we had nice plywood like that over here. Wouldn't use anything else. Instead it is so darn expensive nobody wants it so nobody brings it in either.
