Use rolling carts for things that you don't use daily. HT ovens, forges, occasional use tools, etc. The HF rolling welders carts are perfect for many tools.
Make a "Drop -In" spot on your bench top. It is a place where the top has a cut-out section with strong braces or lips below it so you can drop-in a piece of counter top or other item. Make a batch of cut-outs to fit this. Mount things like bench grinders, disc sanders, tang stamping jigs,clamping jigs, and other smaller tools on these. Place them on the shelves, or in a rack you build to hold them when not in use, and just "Drop-In" The tool you need when you need it.(You can even put a jig or small tool on both sides of the Drop-In ,and flip the insert to the side you need.) When no tool is needed, you can either put in a blank piece of bench top, a piece of butcherblock, or a piece fitted to your granite surface plate. The sky is the limit for how many things you can make interchangeable with this set-up. If you build a "Slide-In Bread Rack" like the bread and buns come to a store on, the inserts can be stored out of the way, and rolled around, easily. You might want to see if you can score a rack from someplace and make the inserts to fit the rack. Commercial kitchens use them to hold trays of cooked food,too.
Put all lighting on dedicated circuits...and allot plenty of breakers for those circuits. You want all the lighting you can get...plus some.
Decide how much power you need, and add 50% to that....or you will wish you did later . 200 amps should be the minimum.
3Ph power is superb if available.
Have extra breakers in the box for future circuits. Run power everywhere when building the shop, Quad boxes every six feet sounds crazy, but will be very useful. Run 220 to all areas where it could be conceivably needed.
Put a NEMA box outside that can be opened up and will have a 30 amp 110 and a 30 amp 220 socket in it. Being able to work outside from time to time is really useful.
Start clean, and stay clean. Once the shop gets cluttered and filled with grinding debris, it will never get cleaned again.
Ventilation and air quality. - Put is a ventilation system to
exchange the air with outside air. If there is no air going out, incoming air won't do much good.
Build a good dust extraction system, with a spark trap for metal grinding. A separate hanging air filtration shop filter that runs on a timer is a superb idea to keep the air clean. It should be set up to turn on when you come in, and turn off an hour after you leave.
Try and group tasks. Grinding in one area, forging is another, etc.
STORAGE - this is the smallest part of some shops, but the largest part of what is in most shops. Think about that - everything in your shop but the piece of steel in your hand, and the tool you are using on it, are technically in storage. Build lots of shelves, racks, cabinets, and overhead storage. If you get in the habit of putting things in their place, you will always be able to find them. If you get in the habit of just setting things on the floor or in piles against the wall....it will end up looking like most of our shops
