Jeremy,
After looking at your layouts I think I can help improve your shop layout.
The biggest things I notice that need to be addressed are:
1. You need a larger shop.
2. Your stack of wood is too large.
3. You have too many [strike]toys[/strike] tools.
While I can't help with "1.", I can swing by this afternoon and help you with "2. and 3." Just load in my truck. You can come by anytime and look at or even use the tools. No guarantee on the wood. :lol: :lol:
On a serious note:
You are really trying to put 20 lbs of tools in a 10 lb bag. This can work if all the big players are mobile. My shop is 20 x 24 detached, very similar to the size you're in. I'll offer how I would place the big stuff based on the first layout you presented and let you put the less-used machines "wherever".
The center of the shop is the TS and general work area (assy table). Peripheral equipment is located based on workflow.
I like the TS position in the first layout. Rather than a small outfeed, I'd go with an assy table outfeed. My assy table is a full sheet of 3/4 melamine sitting atop a layer of 2x4s which are laying across STOUT sawhorses. My stack of AD lumber is stickered UNDER the table. I am not advocating this approach but it's the best solution I could find to deal with AD lumber. My TS is mobile so that it can be moved when I need to work on the TS side of the assy table. My assy table is darn flat. A 4 ft x 8 ft flat surface is nice to have.
I would relocate the planer and jointer to the area where your lumber stack is located in the first layout. Situate you machines so that the planer needn't be moved. Keep the planer infeed open as much as practical. When planing, move the jointer toward the TS slightly. The jointer can be moved/rotated if needed as a post-outfeed stock laydown when planing large/heavy planks or panels. NOT to support while planing but as a resting point (stock lies on planer outfeed and jointer table). This allows you to do 1-man planing without having to continually juggle large heavy pieces.
This arrangement will allow you to stack rough stock on the assy table or saw top for dimensioning. You will have space to move stock as it is planed or jointed in an organized manner. The small work triangle means you don't make many steps while dimensioning. I typically face joint, using the assy table and TS top to stack. Then I plane, using the jointer infeed table and assy table to stack. Edge joint using assy table and TS top (closest to jointer). Once edge jointed, rip and stack on RHS of fence on TS/assy table.
I would place the router table where you have the bench and bench top tools, closest to the drum sander. The bandsaw will be between the RT and the DP. I would recommend you place the BS on Zambus-style casters. Simply roll it forward toward the assy table/TS and lock casters to rip/resaw long stock. You won't believe how well this works. I don't believe you realize how much you will use a bandsaw. It's going to become one of your go-to machines. I know you have a BS now but you are about to get a different level of machine. You will be grinning a lot.
I have a CMS on a dedicated bench. I value the bench much more than the CMS. If I were finishing homes for a living this wouldn't be the case. But, I'm primarily building furniture, frames, toys, knick-knacks. Since I have a workable cutoff sled and a good miter gauge with fence for the TS, I just don't use the CMS very much except to crosscut prior to dimensioning. That said, my CMS/bench is located where you have the scrollsaw and multi-router. My DC is next to the CMS bench.
I have one DC line that serves the TS, planer, jointer. This line goes through a trashcan separator to remove heavies. I use a second line to serve the BS, RT, belt/disc sander. Since these machine generate more "fines" they go directly into the bags. My lines are flex hose. They work just fine. I only have a 2HP DC. I am not going to get carried away with extravagant DC layout/cyclones/filters using a "2HP" unit.
In terms of elevation, my TS top is just a smidge higher than the assy table. The TS top is also higher than the jointer top. This means that the jointer top will not interfere with TS operations on long stock.
I would take pics but my shop looks like a disaster zone right now. I have not done any work there for a week or more and have two projects "open".
I like the way you situated the Belt/disc sander. I would probably put the scroll saw in that same area and keep one of those doors locked up.
My workbench is located where you have the chop saw. It works there for me. If/when I use up the AD wood under my assy table I will relocate the bench where the assy table sits.
I'm not really sure where your KD lumber is stored. MY KD lumber is in a rack in the corner with your compressor/door. Sheet storage is overhead. It sucks to dig out sheets but I just don't spend too much time doing it. For all the inconvenience when I need to retrieve a sheet of ply it's worth it to me. Wall space is very valuable in a small shop.
DON'T position your 220V machines based on 220V ckt access. Run some EMT and place a receptacle where it makes sense based on work flow. Given your current level of WG disease, you will likely upgrade to a few more 220V machines, at least for DC and possibly planer. (There's one for sale...right, Alan?). :lol: :lol:
