The jaw for the front vise needed to be 10" long - to span the distance from the leg to the end of the top, 1-1/2" thick - to allow for benchdog holes to be drilled in it, and 5" tall. The end vise was mounted 3/4" lower than the front vise, and the screw and guide rods were thicker, so its jaws needed to be at least 6-1/2" tall. Again, they needed to be 1-1/2" thick to allow for benchdog holes, and 23" long to span the width of the bench.
The top is supported by the top ends of the legs and the top sides of the top stretchers. Stand your legs on end on a flat surface (like my door) and see if they wobble. If you have an end that isn't quite stable, use it as a foot, where the leveler will make it's flaws unimportant. Check the top edge of each stretcher for straightness. If one has a bit of a bow, use it for a lower stretcher. It's less critical that the shelf be well supported along its length.
It doesn't get much better than a day at the woodshop! I've taken several classes from cutting boards to turning vases. It is always fun and informative! All of the machines are top notch and the instructors are great! I've toyed with the idea of a membership but I think I'll take a couple more classes before doing so! I can't wait to see the new location! :)
Cut 15 top boards 5 ft. long and rip them to 3 in. wide with a table saw so the top will glue up flat without the typical rounded edges of 2x4s. For the leg slot, cut two of the top boards into three pieces: a 39-in. middle piece and two 7-in. end pieces. Glue and screw the top together, one board at a time, with 3-in. deck screws, keeping the ripped edge facing up and level with the adjoining boards. Use a corded drill so there’s plenty of oomph to drive each screw below the surface. Note that the third glue-up from each end is where each leg notch is inserted. You can also create a nifty tool tray in the top by notching the three top pieces with a jigsaw. Clamp every 8 in. or so before driving in the 3-in.deck screws. Predrill the screw holes near the ends to prevent splitting. When you’re screwing on the 7-in. long 2x4s to create the leg slots, use a scrap piece of 2×4 as a spacer.
Having done all this, I'm not sure I'd do it this way again. It might well be faster to layout the positions with compass and straightedge directly onto the top. Either way, you'll want to use a scribe rather than a pencil. Scribe lines are hard to see, and impossible to photograph, but the scribe and compass points click into them, allowing a precision that pencils simply cannot match.
The reason I'd cut out the rectangles in the vise support was that I'd intended to put a benchdog hole through each, and I wanted the thickness of the top to be the same for all of the benchdog holes. Where I messed up was in not cutting out the ends, between the bolt tabs. I'd intended to put a benchdog hole through there, as well, but I'd forgotten to cut out the segments prior to glue0up.
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
Out of all the shed books I have read, this book stays by my side while I hammer in the yard. The book is well written by what appears to be a non professional book writer (A Good Thing). It reads as if you are getting advise in laymans terms from your neighbor "The Craftsman", a welcome change from the DIY books, that assume a level of expertese. The level of detail is high and discusses gotcha's, advise, and trade "secrets" that could have only come from years of personal experience building sheds.
