So drill the benchdog holes through the MDF layer. Begin by laying out their positions. You'll want these to be precise, so that the distances between the holes are consistent. The vises you are using will constrain your benchdog spacing. My front vise worked most naturally with two rows of holes four inches apart, my end vise with two pairs of rows, with four inches between the rows and eight inches between the pairs. Because of this, I decided on a 4" by 4" pattern.
We want to make these pieces square, and of identical length. Square is a matter of making sure the saw blade is square and that the cutting guide is square. The trick to getting the pieces of the same length is to clamp them together and to cut them all at once. For the 4x4's, that means making a rough cut in each first, so we have four pieces, each 3-4" longer than we need, from which we'll get our four legs.
Ok, I’ve had my morning coffee and now it’s about time to get out to the shop to see what I can do to make that bench a little more pleasing to my eye. I like that Craftsman flair idea. That was my intent at the time I built it, too bad I got lazy and rushed the job. It’s not like I was going to make hundreds of benches for someone else and would never see it again. I should have taken the time to make it the way I wanted it to look. This could keep me entertained for awhile. I see major surgery in the forecast! Gotta plan it all out just right.
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.
