One you have the vise jaws shaped so that the vise moves freely, mark and drill holes in the fixed jaw for the bolts that will hold it to the bench. With these drilled, reassemble the vise and mark the location of the holes with an awl. Disassemble the vise and drill the holes through the stretcher, then reassemble the vise and bolt the inner jaw in place.
Put the countertop on the base, put the MDF on top of the countertop, and line up the marks you drew on each end of the MDF with the countertop below it. When you have it lined up, clamp things down, and route the edge of the MDF using a 1-1/2" or longer flush-trim bit, with the depth adjusted so the bearing rides on the countertop. I clamped a couple of scraps of doubled MDF at each end to give the router base something extra to ride on at the ends.
I’ve built workbenches with more than 100 students. In every class, there’s one guy who wants to put a vise on every corner of the bench. Not because it’s a partner’s bench for two people. Just because he wants it that way. While I support your freedom to choose, I also don’t want to spend two weeks installing complex tail-vise hardware on your bench when we could be building furniture instead.
If the holes of the first jaw are in the proper position, drill holes in the same locations on the other jaw. I lined the drilled jaw on top of the undrilled jaw, clamped things down, and then drilled about 1/4" into the undrilled jaw, to mark the location. Then I removed the drilled jaw and drilled out the marked locations the same way I did the first.
A workbench needs to be heavy enough that it doesn't move under you while you're working, and stiff enough that it doesn't rack itself to pieces under the forces that will be placed upon it. It doesn't take many hours of planing a board or hammering a chisel for a worktable made of nailed 2x4s to come apart. Traditional bench designs use mortise-and-tenon joinery, which is strong and rigid, but not really suited for a novice woodworker who doesn't already have a bench.
I decided to make my own top out of white ash because I had access to a planer and jointer at my local college where I was taking an intro woodworking class. Trim and vice jaws are white ash as well. Everything else is built pretty much as jdege describes. A plunge router with a 3/4" spiral up bit really made quick work of the dog holes. Finished with Danish oil.
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 had a similar experience with running electrical power to a shed. It turned out that I could build a 12x12 shed without a building permit as long as I did not run utilities, but getting a permit opened a whole new set of requirements that forbid me from having a shed at all. And when the nosey old woman next to me kept calling the building inspector on me, it was suggested that I could run an extension cord out to the shed anytime I wanted as long as it wasn’t fastened in a permanent manner.
Synopsis: No room in the garage? Basement not an option? Consider what Ken St. Onge did when he needed shop space: He bought a prefabricated shed and converted it into his full-time woodshop. Because a pre-built shed doesn’t need a cement foundation and is built in a factory, it’s much less expensive than building an addition or stand-alone shop on your property. It can have taller ceilings than a garage and bigger doors than a basement, both big pluses for a woodworker. You can put a shed just about anywhere, too. Here’s a soup to nuts look at Ken’s experience, so you can gauge whether a shop in a shed is right for you.
