Lay a leg flat on your work surface, with the countersink side of the thru-holes down. Stick a piece of threaded rod in each hole. Take a stretcher that is marked to have one end adjoin the top of this leg, stick a dowel center in its dowel hole, line it up against the leg, using the threaded rod for positioning, You want the top of the stretcher to be even with the top of the leg, or just slightly above it. Give the end of the stretcher a whack with your rubber mallet. This will leave a mark indicating where the matching dowel hole in the leg needs to be drilled. Repeat with the lower stretcher than adjoins this leg. Then repeat for the other leg that will form this trestle, and the other ends of the two stretchers.
@cahudson42 I bored the holes in my sandwich top with a 3/4" power auger bit with the drill in a portable drill guide that kept it vertical and in a way a bit like a plunge router. The guide screw of the auger was dead easy to centre over the laid out grid points. The holes are dead straight and clean sided. The auger bit was new which probably helped. As stated I have three rows from an end vise running the length of the front as well as from the front vise and holes in the front apron to support long pieces as well.
to allow 9' at the peak, I like a "shed style" roof, but that may not fly in your HOA.I'd put double doors on or one large one, pour a slab, or use patio blocks then lay down Wolman. plywood for a floor, I would use foam insulating board everywhere I could, walls, floor and ceiling. A few bin type windows or sliders would let in light and fresh air. If you can't get away with your wiring idea, I would use a HD 30 amp twist lock extension cord with an "outside weatherproof outlet" mounted on the home professionally installed for code, 2- 8' long flouresent lights, and a 20 amp outlet inside for a heater and dehumidifier. Dehumidifiers draw about 5-6 amps. You might be better off with a small 6000 BTU window or wall mounted AC unit,( $100 on sale at the Depot), it will take the moisture out of the air and cool it as well in the summer. I'd use thin wall conduit around the shop with about 4 double duplex boxes. You may be able to bring 220v. in and then split into 2-120v circuits. If you make ANY dust in this confined space you must first catch it with a shop vac, then filter the air, and wear a mask. A bathroom ventilator fan would exchange the air and be quiet. A slab in front would allow sawing outside weather permitting. A roll up canopy over the door way would provide "shade" and rain protection. I know this sounds like a lot of work, but I know you can do it if you try. You can get plenty of "free" advice here and from an expert close to you. My neighbor enlisted the help of a handyman for building his 2 sheds and they became friends and did tool swaps and labor trades for time worked. My advice to you.. go 4 it! bill
Applying the oil is easy. Put on some vinyl gloves, pour some oil in a bowl, take a piece of clean cotton cloth the size of washcloth or smaller, dip it in the oil, and apply it to the wood. You want the wood to be wet., you're not trying to rub it in until it's dry. Apply oil to the entire surface, and then go over it looking for dry spots, applying more oil as needed. After fifteen minutes of keeping it wet, let it sit for another fifteen minutes. Then apply another coat of oil, and let it sit for another fifteen minutes.
The Classic Workbench is simple to use. The leg vise is used primarily for working the edges of boards and the ends of narrower boards. This is self explanatory. To work the faces of boards along the grain, tap up the planing stop (don’t make it any higher than necessary) and butt the end of the board into the teeth of the stop. With the right technique you can plane across wide boards without repositioning the board. You usually don’t need to tap the opposite end of the board to engage it with the stop, but in some cases, especially with rougher stock, you may need to give a tap with your mallet. Working the faces of a stack of boards is extremely quick with the planing stop since you don’t have to open and close a vise constantly. To work across the face of a board, make yourself a doe’s foot and position it at the back corner of the board, holding it down with a holdfast. The doe’s foot is simply a piece of wood with a V-shaped notch cut into one end. The bottomsurface of the doe’s foot can be lined with sandpaper or Crubber to help it stay put on the bench top. To work long boards, fasten a batten to the right leg with a holdfast and use that to support the end of the long board. We’ve found that a deadman is not necessary for the majority of work, especially on a bench of this length. For working the ends of smaller boards the leg vise can be used, but for precision work like dovetailing, we use and recommend our Moxon Vise.
Raphael Berrios is one of our Foundations of Woodworking scholarship students in Spring 2016. He also took our Timber Frame Tiny Home course and brought home one of the structures to finish for himself (you can follow his progress on his blog!  Here’s what he had to say about what led him to PTSW, his experience so far, and thoughts for the future:
Our sizing options range from 6′ x 8′ to 13′ x 36′, and even larger depending on your chosen style. We’ll work with you to design a custom solution based on your needs and property, with many door options, window options, trim colors, shelves, siding and roofing choices to choose from. We deliver a large portion of our sheds fully assembled using our lightweight “mule,” but we also provide an on-site build option for those really tough to access sites.
I would say take the shed, you'll find some use for it. I have contemplated this question also. I have a 20' x 11' basement shop, thats quickly loosing space. If you live in an area with a harsh winters (say the Midwest), does it make sense to heat the shop through the week if you are only working in the shop on the weekends? Or do you run the heaters just when you are working in the shop? What kind of heaters are recommended (radient, wood stove, etc.)?
When the holes were complete, I flipped the legs and drilled the countersinks with a 1" Forstner bit. Trying to drill a countersink when the center was already drilled would be impossible with a spade bit or an auger, but Forstner bits are guided by their edges, not their center, so they can handle this job. On thing about Forstners, though -- they have a tendency to skitter around a bit when starting, before they bite. An easy fix for this is to drill a hole through a piece of ply, and to clamp that to your work, creating a jig that will prevent the bit from drilling in the wrong spot.
After I left the magazine for a new job, I did all of my woodworking in my small two-car garage, but it was a struggle. Power, lighting, and temperature control were limited. And because I shared space with our cars I was always moving machines around, often while in the middle of a project. On top of that, my tool and machine collection had long since eclipsed the space. For all these reasons, fixing up the garage wasn’t an option. My finished basement is a family room, so it was out, too. An addition to the home or a stand-alone building would have been too expensive. I had to find a better path to a shop.
