A woodworker's workbench isn't a table, it's a work-holding system. It's not something you set things on top of, it's a tool that holds your work. Where a worktable might have a machinist's vise bolted to its top, a woodworker's bench is built to accommodate a number of different workholding mechanisms, such as bench dogs, planing stops, hold fasts, or board jacks, and will usually have one more woodworker's vises integrated into its structure.
My wife has given me the OK to buy a "Rancher"-style shed from Lowes and have it installed in the backyard. The discounted installed price will be about $2,600 and this includes the 12' x 8' structure along with a lot of upgrades (twin metal doors, a window, 2 skylights, storage, vents, etc.). I can save about $300 if I build it myself, but my skill level isn't there yet, so I'm going to pay Lowes to assemble it. (See Post #12 below for some photos of the shed and the space I have to work with.)
If you're using drywall screws, you'll want to countersink the holes. Drywall screws are flat-head, and need a countersink to seat solidly. If you're using Kreg pocket screws, the way I did, you won't want to counter-sink the holes. Kreg screws are pan-head, and seat just fine against a flat surface. Both drywall screws and Kreg pocket screws are self-threading, so you don't need pilot holes in the second sheet of MDF.
Once you start spreading glue, you have maybe five minutes to get the two panels mated, aligned, and clamped together. So make sure you have everything on-hand, and you're not gong to be interrupted. Start squeezing out the glue on one MDF panel, and spreading it around in a thin, even coating, making sure you leave no bare areas. Then do the same to the other MDF panel. Then pick up the bottom panel and flip it over onto the upper panel. Slide it around some to make sure the glue is spread evenly, then line up one corner and drive in a screw. Line up the opposite corner and drive in a screw there. Clamp all four corners to your flat surface, then start driving the rest of the screws, in a spiral pattern from the center.
Post Woodworking’s Hampton shed is a major standout in design. The sleek farmers porch immediately draws the eye into its pure New England charm and provides the utility of shade and a cool place to sit and enjoy a cold one. Like all of our sheds, the six-panel doors which add to the structure’s aesthetic come standard. They’re made out of fiberglass to last through many decades out in the elements.
