Okay. Here goes.
1. Consider the white cabinets and shelves with doors that you assemble yourself.
2. You can get ready made countertops in a choice of several colors for your worksurface at home improvement stores fairly cheap.
3. Epoxy the floor or add linoleum or tiles so you can find the flying pieces.
4. Use vertical space.
5. Consider storing items on vertical pegboard panels that swing out on piano hinges to use cubical space.
6. Instant-on fluorescent lights for general lighting-no flicker.
7. OTT lights for closeup task work.
8. As much horizontal workspace as you can manage. Nope. That's not enough. You need more.
9. A place to run your paint booth exhaust to the outside.
10. Remember A,B,C. Keep the tools and such that you use all the time where you can reach them without moving, your "A" space. Keep the items you use from time to time where you can reach them without leaving your seat, your "B" space. Keep the seldom used items where you have to get up to get them, your "C" space.
11. Comfortable chair. Here's a place to splurge.
12. Bar refrigerator.
13. Many outlets with adequate amperage and wiring gauge.
14. A temperature and humidity reader.
15. A sign that says, "NO GURLS ALOWED" (Peter Pan).
16. Don't forget a bookshelf for your reference materials and another for "show and tell".
17. You STILL don't have enough horizontal storage space. How about a slide out shelf under your worksurface, like a keyboard drawer, to keep sub0assemblies nearby, but not in your prime work area.
18. Yes, I'm an aero-SPACE engineer.
19. I'll try to post some pictures of my playroom. If I only had talent!
