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.
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.
The base needs to be as wide as the sum of width of the guide strip and the distance from the edge of the shoe, plus a bit extra, With my saw, the overhang is 3-1/2", so I made my guide strip 5-1/2" wide. The distance between from the edge of the shoe to the blade is about 4-1/2", so the base needs to be at least 10" wide. Since I was working with a 24" wide sheet, I just sliced it down the middle.
This is technically a vanity factor, though the ability to store tools and other supplies at quick reach can be a time and energy saver. At the least, you will want a bench that comes with a shelf underneath. This will allow the storage of larger items that can otherwise be difficult to find a place for. Drawers are the other popular storage for benches and can make retrieving tools much easier – just make sure the inside of the drawer is lined with felt or the wood may prematurely dull your tools.
When you have the other leg seated, the threaded rods will extend father than you want them to. You'll want to mark them so they can be cut to length. Place a washer and a nut on each threaded rod, and then tighten down the nut to pull everything tight. Depending upon the wrench you are using, and how much longer the rod is than it needs to be, you may find it necessary to stack up a number of washers, so that the nut is positioned where the wrench can operate on it.
Our instructors work out of a 27,000 square-foot facility, where over 100 stationary and portable woodworking machines are available. We emphasize hands-on training and real-world experience, and all classes are project-focused. Over forty different classes cover topics including faceframe and frameless cabinet construction, CNC woodworking, architectural millwork, table and casegood construction, hand tools, woodturning, and veneering.
I don't like to be ignored either. I came the same day Mahndo left after waiting 30-45 mins. I left a note with name and number but no one even called me back. I was completely ignored. I found a class over at The Corona Heritage Park in Corona instead. Their instructor answers when I call or text. Nice to be acknowledged! Going to finish beginning and take advantage of the key access in their intermediate class.
Traditionally woodworkers (joiners) learnt their craft working as an apprentice in the Master Craftsman's shop doing the grunt work and learning by assimilation over many years. Our approach is a little different. We're making the assumption that you're smart; are developing or already have a passion for woodworking; and can devote three months to intensive learning.
I marked the holes by putting a dowel center in the end of a long piece of 1" dowel. Run it through the holes in the base plate, and bang on its end with a mallet. Rotate it a bit and bang it again, and repeat. Odds are the dowel center won't be precisely in the center of the dowel, so you'll be making a small ring of marks. The center of the hole is, of course, the center of that ring.
