JF needs to ship me some of those grey boxes with the green latches. Full of course.
I'll pay the shipping one way.
My experiences: all surfaces need to be the same height. That includes the radial arm saw, the table saw, the router table, shaper, jointer, and the miter saw table. Most of them on wheels (if you have a solid floor). It makes it SOOO much simpler when/if you need infeed and/or outfeed tables, or supporting a piece of wood, steel, etc. You will never regret having everything the same height (well, if you do, make a cart for that thing).
I made mine with some curb side finds -- old cabinets. I forgot to leave enough overhang around the top, pain to clamp things down. Corners are not your friend -- you will always have something that you wished was hanging off the ends (so you can work on either end, or one end has some other 'thing' attached to it, etc). Some folks put a little door in the wall if in a corner -- lets a piece of wood stick out or be inserted from outside, etc .
Oh, and you WILL want a toe kick. I stuck a board along the front of my cabinets for some forgotten reason (strength, mice, room for stuff to roll under it, ?). I miss having a toe kick.
Then there's lighting. Like power and space, you will never have enough. Fluorescent tubes and several of them (to keep shadowing away).
And counter tops: old doors (smooth solid core); old formica (if it doesn't have bull nose); melamine. Light/white colors help. Slightly rough surface (like melamine) keep the reflections down.
Good luck on the 'perfect' $olution. Still working on mine!
