My stuff is organized much like others shown here, I won't bore you with the photos (but can if you are bored!). Quick version is I have 2 lathes, 4 mills, surface grinder, sheet metal shear, brake, slip roll, etc., etc., etc. Both of the lathes have dedicated Harbor Freight tool chests. The drawers are full of micrometers (outside, inside, thread pitch, tubular, etc.), inserts, telescoping gauges, small hole gauges, dial indicators, accessories (steady rest, follower rest, etc.). Each also has 5C collets from 1/16" - 1 1/8" by 1/64". Chucks are stored on the bottom shelf with some rolls of Emery cloth. Quick change tool holders are stored on racks on the splash shields.
Two of the mills (Bridgeport and Jet JVM-830, 3/4" sized BP) have racks built to them with R8, ER32 collets, drill chucks and wrenches. There's a HF 26" top/bottom roller cabinet with "mill stuff". Reamers, end mills, every way known to mankind for finding the center of a hole/boss, screw machine drill bits, parallels, etc.
Adjacent to the 2 mills and 2 lathes is a 6' tall 18" x 36" storage rack with more stuff: Rotary table, dividing heads, micrometers up to 12", gauge blocks, tool post grinder, dial indicator stands, lantern-style tool holder storage box, etc.
An additional mill is a Tormach 1100S3. It has a similar HF tool chest dedicated to it with 30+ TTS tool holders, vise soft jaws, parallels, end mills, micrometers, height gauge, electronic tool setter, etc. Also have a roll-around tool cart that fits under one wing of the mill. That holds 20+ TTS tool holders, 4-th axis, chucks, etc.
My Atlas horizontal mill is on a Husky or Waterloo rolling box with wrenches, horizontal cutters, arbors, end mills, etc.
A lot of my excess tooling is stored in a couple of 4' x 4' x 2' deep wooden cabinets with full-extension glide drawers. Everything is labeled, so if I need a 1/8" carbide 4-flute end mill, I know right where to go.
