Happy bench building folks. I hope you make it your own and not worry too much about what someone else thinks it should be. Use the rules as a guideline, they have validity, but make it your own in the end. If the rules fit you that’s great, if they don’t quite fit you then make it to fit yourself. It’s you using it, not some guy making a nice living off of telling you how he thinks you should do it. One size does not fit all. Never has, never will.
With my second attempt at edge guides, I made the other rough-cut. On this, the edge guide worked fine, but the end of the cuts revealed that the saw blade wasn't quite square. So I adjusted the blade, clamped all four legs together, and made what would be the first final cut, if it came out clean enough. It didn't. I'd let the saw drift a bit away from the guide edge. So I adjusted the saw, moving the guide back half an inch, and tried again. the rough-cut parts were a couple of inches longer than they needed to be, so I had room to work with,. It's only the final cut at the other end that you only have one chance at.
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.
Glue up the trim on the end, first. Do a dry fit, first, then as you take it apart lay everything where you can easily reach it as you put it back together again, after adding the glue. To help keep the edge piece aligned, I clamped a pair of hardboard scraps at each end. I used the piece of doubled MDF I'd cut off the end as a cawl, to help spread the pressure of the clamps. Squeeze some glue into a small bowl, and use a disposable brush. As you clamp down, position the trim just a little bit proud of the top surface.
2 - use a plunge router with a bottom bearing cuter bit such as this from rockler: http://www.rockler.com/product.cfm?page=25160&site=ROCKLER .... I thought to use the short one as I plunge it directly downward in the centre of the hole until the bearing reaches within the tabletop hole. I suppose one could use a long one, but the stubbiness seemed more practical (the big bearing ensured accuracy?)
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.
Out of all the shed books I have read, this book stays by my side while I hammer in the yard. The book is well written by what appears to be a non professional book writer (A Good Thing). It reads as if you are getting advise in laymans terms from your neighbor "The Craftsman", a welcome change from the DIY books, that assume a level of expertese. The level of detail is high and discusses gotcha's, advise, and trade "secrets" that could have only come from years of personal experience building sheds.
