I drilled from the mark. That way I could ensure that the hole was where it was supposed to be, on the side where the position was critical. I have two 3/8" bits -- a brad point bit that came with my doweling set, and a perfectly ordinary 3/8" twist bit. Brad-point bits are far more precise than twist bits -- they're more likely to start where you want them to, and they're more likely to stay straight. My problem is that my brad-point bit wasn't long enough to go through 3-1/2" of wood. So I started each hole with the brad-point bit, then finished it off with the twist bit. I clamped a piece of ply on the back, to reduce tear-out.
I don't see anywhere you mentioned the over all length of the bench top. A piece of 1 1/2" x 25" x 8' glued edge oak at Lumber Liquidators costs $192 including tax. Two piece is almost $400! Would that be better if I use two IKEA 1 1/4" x 25" x 74" solid Beech ($99 each plus tax) on top of a layer of 3/4" Birch plywood. That would be 3 1/4" over all.
The engineering involved in building this garden bench is pretty simple, and we have provided some links to get a full cut list and plans with photos to help you along the way. Additionally, to the stock lumber, you will need wood screws, barrel locks, and hinges to complete the table. A miter saw or hand saw is also extremely helpful for cutting down your stock to the correct angle and length.
I made my version of a Roubo bench over 20 years ago. According to the latest bench rules it is too tall, too wide, has too many vises (I use both sides of my bench and that might be a no no, not sure ), and has far too many holes. Did I mention that I have a double row of dog holes with a user made dual row wagon vise? I had no idea they were called a wagon vise back then. Being a tool maker and tinkerer at heart I just made a vise that I thought at the time was an original idea for the main side. Couple of dowels in a piece of wood straddling the two rows and I have a bench stop, or a different variation gives me a 3 point clamping system. If that isn’t bad enough it also has drawers on the bottom to store seldom used tools and supplies. Maybe if it had taken me a few weeks to drill all those holes and mount a few vises I would only have one vise and 8 holes too. I dunno
5. The Woodbook: The Complete Plates. This one contains no instructions, no techniques, and no how-to information. Rather, it's the most complete collection of American wood samples ever created. Assembled between between 1888 and 1913 by New Yorker Romeyn Beck Hough and originally published in fourteen volumes, Taschen's publication "reproduces, in painstaking facsimile, all of the specimen pages from the original volumes... For all trees, now arranged in alphabetical order, three different cross-section cuts of wood are represented (radial, horizontal, and tangential), demonstrating the particular characteristics of the grain and the wealth of colors and textures to be found among the many different wood types. Also included in this special edition are lithographs by Charles Sprague Sargent of the leaves and nuts of most trees, as well as texts describing the trees’ geographical origins and physical characteristics."
Of course, few benches can be ideal, and this one does have some drawbacks. That being said, most of the disadvantages of this bench are minor annoyances rather than deal breakers. For instance, this bench does not include any kind of storage whatsoever. Though, it does have the option of adding numerous additional features like a storage area. Still, for the bench, you would expect a drawer at the very least, maybe a shelf below the main table area.
