Usually ducting is well covered and one of the first things considered, however, most people initially neglect clean up when designing shops. With growth, I have a very cluttered shop that makes pulling shop vacs around frustrating especially if you’re at the wrong end of a 5m flexible hose without having to struggle with the vac (the practice of in no doubt exacerbated by those ridiculous vacuuming ads on TV). As my setup is retro fitted, it may not be pretty as it is ducted overhead, but it is productive. I have a centralised heavy duty ‘shop vac’ (rigged with a Dust Deputy) and 50mm stormwater piping radiating to selective parts (corners) of the workshop. I use 50mm water diverters to act as blast-gates to control the flow of air (I have a bank of them running down one full side of the workshop spaced about 5m apart). When I need to clean a part of the shop I plug the vac into the appropriate overhead vent, organise the diverters and attach a 5m flexible hose to the working end. I have the vac on a remote (one of those that control power points – all my dust extraction is controlled by these – after modifying any proprietary mag switches) and I can vacuum any part of my workshop without having to go and manually switch the vac on. I have bought some cheap off market flexible hoses and spread them at the extremities of the workshop. Each outlet will accept the hose. Hint – I bought a fairly low end 3D printer ($800 (Aust)) and I can print any sized coupling to accommodate all those non-standard ‘shop vac’ hoses/fittings to accept my proprietary shop vac accessories. Duct tape is now reserved for the few threaded non-standard couplings.

A landscape designer friend of mine tells a story about the college he went to. During his years there, the university embarked upon an ambitious building plan, adding several large structures around the main quad: a dorm, a chemistry lab, and a couple of others. The look of the place, which had remained unchanged for a century, was suddenly transformed, as glass-and-steel modernist structures were interspersed with the earlier ivy-covered stone Victorian-Gothic.

Pocket screw joinery is a system—employing special drill and driver bits—used to join boards or pieces of plywood to one another. Installing pocket screws involves using a jig to drill a sharply angled, 15-degree hole through the back of one board, then driving a special screw through that hole into the second board to draw them tightly together. Learn how to use pocket screws here. It’s often used in cabinetmaking and furniture building. Here’s how to build cabinets with pocket screws. The term “pocket” comes from the design of the hole which contains an upper “pocket” for the head of the screw to push against; this pocket also hides the head of the screw.

I looked around at many versions of Taiwanese drill presses. I ended up purchasing the Ridgid DP15501 15" drill press because I liked the way the quill stop was made, the work light, key stor­age, and the easy access to the belt change system. This machine was also on sale when I needed it, so that made it a slam dunk. Choose the one that suits you, as they’re all very similar. The table is large enough, and the distance to the column is large enough to allow you to do most anything a small shop needs. 

This simple jig makes laying out circles a breeze. Drill a 1/8-in. hole through every inch mark on a ruler or yard-stick. To draw a circle, place a pin through the number “1” into the center of your board. Add 1 in. to the radius of the circle you wish to draw, and insert a pencil into this number. Using the pin as a pivot, rotate the pencil to mark the circle. — Edwin Constantino. How to Cut Curves in Wood

Since most of your assembly will be done on the assembly table, it just makes sense to have your clamps nearby. If you’re short on wall space, try a rolling clamp cart! If you use your workbench for assembly, keep your clamps near the workbench. Check out these two helpful articles for clamp racks: A Simple Utilitarian Clamp Rack and A Parallel Clamp Rack.
A kind’a unrelated question. I just finished building the lumber storage rack/sheet goods cart from your “racking my brain..” video. I see you went with the metal wall storage rack in your new shop (which I would love also, just can’t afford) but, I was curious why you didnt put another sheet goods cart. Previously I had the stand up sheet goods storage box like I see your current pictures but, from what little I have used the cart, I like it better than the stand up storage. Its easier to get things in and out and see what all I have. The only draw back is that I can’t store as much on the cart as I could with the box storage.
I have never worked with my bench up against the wall, because I like to work from all 4 sides of my bench. I do like my machines pushed up against the wall and a large open space in the middle of the shop to facilitate easier movement. I have a Minimax combination machine so by necessity my tablesaw and jointer/planer are bundled together but I would actually prefer they not be (like a Felder machine that breaks apart). I would never put my tablesaw central in my shop, always at one end with a clear entry and egress for the sliding table, space permitting. Putting a tablesaw in the middle always struck me as one thing I’d always have to walk around and/or fight the temptation to stack stuff on it.
Enter the garage heater. These space heaters are specifically designed to warm up wide open areas and to function under much tougher circumstances than you’re likely to find in the average house. A well designed garage heater will offer at least 5,000 watts of heating power — enough to warm 750 square feet of space. A smaller heater might take off a bit of the chill, but to really warm your workshop — and keep it that way — you’ll need a heater of this size.
An interesting variation of this layout is displayed in Jim Tolpin’s shop, shown in the photo at right. Tolpin located his jointer to the left of his table saw, its height low enough to allow panels cut on the saw to pass over the jointer. To save space, his portable planer lives beneath the saw. All three tools are oriented toward the garage-style door, which can be opened to allow long boards to be ripped, jointed, or thickness planed.
