@cahudson42 I bored the holes in my sandwich top with a 3/4" power auger bit with the drill in a portable drill guide that kept it vertical and in a way a bit like a plunge router. The guide screw of the auger was dead easy to centre over the laid out grid points. The holes are dead straight and clean sided. The auger bit was new which probably helped. As stated I have three rows from an end vise running the length of the front as well as from the front vise and holes in the front apron to support long pieces as well.
My first shop was a 8 x 10 ft room, actually a bedroom, with 10 ft high ceilings in a older home in Chicago. I had a 10" Craftsman TS, drill press, 8 1/4" Skil saw which still works, some welding tanks, hand tools and... my bed was a loft across the 10 ft length 4 ft down from the ceiling with a ladder against the wall to get up. I was 16 yrs old then, now I am 66 yrs, have 2 shops with Craftsman power tools up stairs, and Grizzly tools ,a Powermatic 68, a MIG welder, and other tools on the ground floor. I've come a long way, You think? I remember making bases for sculptures called "plinths", my first commission, in the living room, 5 pieces rather large, several ft long and wide. The house was haunted, and my mom told the "spirit" to leave and go back downstairs. There was a cold draft and the straw chair would rustle with no one sitting in it. Wow, does that bring back memories from the '60's.
Cut 15 top boards 5 ft. long and rip them to 3 in. wide with a table saw so the top will glue up flat without the typical rounded edges of 2x4s. For the leg slot, cut two of the top boards into three pieces: a 39-in. middle piece and two 7-in. end pieces. Glue and screw the top together, one board at a time, with 3-in. deck screws, keeping the ripped edge facing up and level with the adjoining boards. Use a corded drill so there’s plenty of oomph to drive each screw below the surface. Note that the third glue-up from each end is where each leg notch is inserted. You can also create a nifty tool tray in the top by notching the three top pieces with a jigsaw. Clamp every 8 in. or so before driving in the 3-in.deck screws. Predrill the screw holes near the ends to prevent splitting. When you’re screwing on the 7-in. long 2x4s to create the leg slots, use a scrap piece of 2×4 as a spacer.
Put the upper panel of MDF on your glue-up surface, bottom side up. Put the bottom panel of MDF on your other surface, bottom side down. (The panel with the holes drilled in it is the bottom panel, and the side that has the your layout diagram on it is the bottom side.) Chuck up in your drill the appropriate driver bit for the screws your using. Make sure you have a freshly-charged battery, and crank the speed down and the torque way down. You don't want to over-tighten the screws, MDF strips easily.
The Classic Workbench is simple to use. The leg vise is used primarily for working the edges of boards and the ends of narrower boards. This is self explanatory. To work the faces of boards along the grain, tap up the planing stop (don’t make it any higher than necessary) and butt the end of the board into the teeth of the stop. With the right technique you can plane across wide boards without repositioning the board. You usually don’t need to tap the opposite end of the board to engage it with the stop, but in some cases, especially with rougher stock, you may need to give a tap with your mallet. Working the faces of a stack of boards is extremely quick with the planing stop since you don’t have to open and close a vise constantly. To work across the face of a board, make yourself a doe’s foot and position it at the back corner of the board, holding it down with a holdfast. The doe’s foot is simply a piece of wood with a V-shaped notch cut into one end. The bottomsurface of the doe’s foot can be lined with sandpaper or Crubber to help it stay put on the bench top. To work long boards, fasten a batten to the right leg with a holdfast and use that to support the end of the long board. We’ve found that a deadman is not necessary for the majority of work, especially on a bench of this length. For working the ends of smaller boards the leg vise can be used, but for precision work like dovetailing, we use and recommend our Moxon Vise.
The book is well written and easy to read. The illustrations, I'm sure were excellent in 1914 and, are still adequite now. Most of the designs seemed repetitive, though. I wish more attention had been given to lashing materials. If you are looking for that you will find almost none here. The book was fun to read and provided enough inspiration to make my brother and me attempt a large hut.
