That looks great ByronBlack. I've struggled for some time with my space (a little less than 3m x 3m). If I were to select the single most effective goal that I have pursued over the years it has been to free up floor space. The room is now crammed with about the same amount of stuff as a few years ago, and even more tools/machines, but with a lot less stuff sitting on the floor. Apart from the obvious benefits of being able to move around more freely, I find that psychologically the room is now far less daunting to spend time in (having to move lots of stuff, or any even, just to get into the room made every project a huge challenge even before it started!).
The things that have worked for me are as follows:
* In areas that are awkward to use for anything else (such as boxed-in pipes in one corner of my room) I have put in small shelves from floor to ceiling. These shelves are small enough to not need much support (so sacrifice less space that extra supports would require) but hold my drills, circular saw, glues, etc.
* I hung boards on the walls (using french cleats) on which I have mounted most of my hand tools. These boards are high enough to allow my bench and router table to sit undernearh and butt right up against the wall.
* My router table, bandsaw, and piller drill are all on wheels so that I can moved them around, or even out of the room when I need to (it is a room within the house so moving stuff out of the room for short spells isn't a problem). I will put my portable thicknesser on wheels too for the same reason, any day now... Good castors are vital for this - I use 4" wheels as I found smaller wheels had trouble with my not-very-smooth floor. For a small space I found 4 rotating and lockable castors per unit was necessary too - having two fixed and two rotating castors per unit made them extremely difficult to manoeuvre in the space available.
* I built drawers into all of my mobile machine units, mostly for tools related to those machines. The units take up no more space as a result but are far more practical now and have freed up a lot of space elsewhere in the room. A side benefit is that the mobile units provide an even better base for the machines now, due to the extra weight.
* For wood storage I attached a few pieces of 4"x2" length of pine to the wall, floor to ceiling, and attached doubled-up standard shelf brackets to these (shelf brackets are
this style). This has worked out very well. They have proved more than strong enough for my storage needs, are adjustable, were free (I salvaged them from work), and I have kept the shelves high enough to allow me to sit 8'x4' sheets of ply resting against the wall underneath. I also roll my mobile machines underneath too. ...mind you, I loaded the shelves and left them loaded for a few days before deciding the whole lot were not going to topple over, before I ever moved my machines underneath!
Unused space within this wood storage area also provides sturdy shelving for things like my air filter.
* I moved to the attic anything that I don't need to use regularly. Moving my powertool boxes to the attic freed up a lot of space - the tools themselves fit onto shelves and into the drawers in the mobile bases.
My space is still cluttered, and tweaking it will be a lifelong job, but the above changes have made it far more work-friendly than I thought at various stages it could ever become. If I had a bigger space I'd still do many of the same things as they have proved very effective at making best use of all available space.
