Regardless of which type of screw you use, you'll need to flip the panel and use a countersink drill to on all of the exit holes. Drilling MDF leaves bumps, the countersink bit will remove them, and will create a little bit of space for material drawn up by the screw from the second sheet of MDF. You want to remove anything that might keep the two panels from mating up flat. I set a block plane to a very shallow bite and ran it over what was left of the bumps and over the edges. The edges of MDF can be bulged by by sawing or just by handling, and you want to knock that down.
A couple nice qualities about this bench include the weight and vice capacities. The weight capacity of this bench is 330 pounds which is decent, though it will not wow you too much. The vice, on the other hand, provides a 7” capacity which is tied for the most on our list. That said, there is only a single vice, and it is not able to be repositioned. This can make things a bit frustrating for lefties as it is a right-handed configuration.
Next is the shelf. Start with the 24x48" piece of MDF. Clamp this on top of the base, and pencil in the outside of the stretchers and the inside angle of the legs. Flip it over, pull out your trusty cutting guide, and cut it to width and to length. Cutting out the angles is simple, with a jig saw. It's not much work with a hand saw. If you took enough care with supporting blocks and stops, you could probably do it with a circular saw. Since I did have a jig saw, I used it.
Foundations of Woodworking runs every fall (September - December) and winter (January-March). The application process for each session opens 9 months in advance of the course start date. Applications will be considered for registration in the order in which they are received. There is no fee for applying. Accepted applicants will be invited to register. We ask for a deposit of $200 at the time of registration to ensure your place in the class.
Frame making may look simple but it is a skill that escapes many. For a frame to properly do its job it has to be perfect, any mistake can be a distraction that takes away from the artwork it surrounds. This class will focus on skills essential to making square or rectangular frames. Skill building concepts will include how to break down and mill...
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.
First, we need to drill out the holes for the screws that will hold them together. While the two layers of MDF are glued, the countertop and the MDF will only be screwed. The oak countertop, like any natural wood product, will expand and contract with humidity changes. If it were glued to the MDF, the difference in expansion of the two layers would cause the countertop to buckle and curl.
Another aspect that might irk some buyers is the fact that the capacity of this bench is less than great outside of weight. The top’s surface area is a bit on the smaller end, though its length is more in line with larger models. The width though is less than two feet which can limit some projects. Similarly, the vice capacity is the second smallest on our list at 4 ½”, though this too can be modded with optional additions.
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.
I agree that I might quickly outgrow a 12x8 shed. Lowes also offers a 12x10 Rancher (same style, but more room), but the 12x10 is 9 feet, 4 inches high, and my community only allows a maximum height of 9 feet. The 12x8 is exactly 9 feet high. I'm afraid of getting "out of spec" if I exceed the height limit and then getting in trouble with the Home Owner's Association. Having said that, 12x10 would be about the biggest size I could get for the available area in my back yard, so even if I hire a shed contractor to do this, the shed would have to be 12x10 or smaller.
