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.
Another comprehensive book by Taunton Press, Wood Flooring is extremely informative, not to mention visually compelling. From subfloors to finishing, and everything in between, you can be sure this is the only book you will ever need on the subject. My favourite chapter was on inlays and curves: using jigs and templates to add circular inlays to a floor, laying out and installing laminated curves, even working with stone and metal inlays … there’s a lot to learn in that one chapter alone. Much of it could be adapted to making furniture. If you want to lay a basic wood floor this book will help you add lasting value and beauty to your home. If you’re looking to one-up your super handy DIY brother-in-law, you can start here too.
I ended up making a number of practice cuts. The first revealed that I hadn't tightened the screws on the edge guide enough. The second revealed that the design of the edge guide provided very little support at the end of a board, because of the cut-out for the router bit. In the "Getting Started in Woodworking" video, they had screwed a piece of hardwood to the edge-guide, to provide a continuous -- and longer -- bearing surface. I may do that myself, some day, but I didn't have the materials at hand, so I clamped some 2x4 scrap to the end of each board, to provide a continuous bearing surface past the ends. The two grooves in the long stretchers and the side groove in the short stretchers have identical layout. I made practice cuts in scrap until I had the edge guide set correctly, then I cut them all with that one setting. The bottom groove of the short stretchers uses a different setup, so it was back to the scrap, before cutting them.
Thanks Chris! I found this page while looking for a link to your e-mail address. I recently finished your erudite volumes on workbench design, and am about to embark on my own bench inspired by your take on the Holtzapffel design. As my vices and planer arrive, I’ve been agonizing over whether to use SYP or rough maple for the top. I don’t have a big budget, so all-maple is not an option. But after reading your ten tips here, I’ll stop agonizing — all SYP it is! This is, after all, my first of what I hope are at least several handmade benches. Your scholarship and craftsmanship are truly inspiring.
Lay a leg flat on your work surface, with the countersink side of the thru-holes down. Stick a piece of threaded rod in each hole. Take a stretcher that is marked to have one end adjoin the top of this leg, stick a dowel center in its dowel hole, line it up against the leg, using the threaded rod for positioning, You want the top of the stretcher to be even with the top of the leg, or just slightly above it. Give the end of the stretcher a whack with your rubber mallet. This will leave a mark indicating where the matching dowel hole in the leg needs to be drilled. Repeat with the lower stretcher than adjoins this leg. Then repeat for the other leg that will form this trestle, and the other ends of the two stretchers.
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.
