Efficient…, and sounds like my shop – sloped floor (everything on casters); the garage door opening to support long rips… so many factors constraining what I’d really like to do with the equipment layout.

With my 1.5-car shop, I’ve had to use the available cube when most woodworkers have sufficient sq’ ft’. Most things are either under, over, or behind something else. No doubt, this can be an absolute pain at times (having to move something to get what I want); but I have only so much room.

Playing Devil’s Advocate for a minute…
1) The CMS – do you need this? I have mine un-mounted in a separate shed. I found that it took-up too much space (right & left, and the slide mechanism brought it out into the working area of the shop. Now, I get by with a circular saw and a triangle-square – mostly. There are times when the CMS is simply the only tool to get the job done, and I haul it to the shop when that arises. However, for the few times that I need a long and precise cross-cut, retrieving the grey space of the CMS has many benefits. For most precise cross-cuts, I use a cross-cut sled on my TS.
2) Sheet Goods – can these be stored behind the Shelving? Or, behind the work bench? I have a garage-shop, and mine sit either behind my workbench or below an on-wall shelf (nuts & bolts, finishes). When behind my bench, I have access from either side.
3) The wall on the left-hand-side (says “lumber…”) – with the sheet goods and the lumber, a great deal of wall-space is consumed. Can you stand-up the lumber (would need an appropriate ceiling height) – I have mine standing on-end, in a large garbage can. Another alternative would be to install ceiling racks (inverted metal T tubes – Home Depot), and hold the lumber flat, near the ceiling. When I start a large project (lengths can be 10’), I can hold 50 to 100 bd ft at the ceiling-level.
4) Can the shelving (nuts, bolts, storage for power hand tools) go above the sheet goods? I have my hand power tools on wire-shelving over-head of the Bench; and nuts & bolts are on a side-wall above my sheet goods; so, no shelving that occupies floor-space.

Just some thoughts – and I do appreciate that every solution is a compromise – one which has to be working-comfortable for the craftsman.
Do Take Care.
