If you decide upon construction lumber, you want kiln dry lumber. Green lumber will warp on you as it drys. Dig through the stacks and pick out the straightest, cleanest pieces. Generally, the boards that are sitting loose on the stack are those that other people left behind, as they sorted through looking for better. Be prepared to move them out of the way, and to dig down to the better stock. Be nice, though, and put everything back when you're done.
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.

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.

Drilling a precisely positioned, deep, wide hole isn't easy, without a drill press. So I bought a WolfCraft drill guide. After experimenting with it, and drilling some test holes, I build a jig around it. I screwed it to a scrap of MDF, and then drilled a carefully-centered 3/4" hole. The MDF can be clamped more easily than the base itself, and the 3/4" hole will keep a 3/4" Forstner bit drilling precisely where it is supposed to.
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.

The Joint Book contains easy-to-follow step-by-step instructions for creating edge and scarf joints, lapped and housed joints, mortise and tenon joints, miters and bevels, dovetails, dowels and biscuits, and provides detailed descriptions of fasteners, hardware, and knockdown joints. This book is the perfect companion for any woodworker interested in improving their joint-making skills.”

As I was handling the 2x4's, during the routing, I realized that I really wouldn't be happy with the look of the bench, if it were made from these unfinished boards. They had stamps, pencil marks, and more importantly, incipient splinters left by the saw, none of which I wanted. And I was remembering what other shop furniture made from unfinished pine had looked like, after a few years in the grime of a shop.
Of course, I, on the other hand, with my Ikea oak countertop, probable went overboard in the other direction. Since I needed to trim the countertop to width,I figured I'd take off a couple of 1/2" strips to use for edging the MDF. I clamped the countertop to my bench base, and used the long cutting guide. I'd asked around for advice on cutting this large a piece of oak, and was told to try a Freud Diablo 40-tooth blade in my circular saw. I found one at my local home center, at a reasonable price, and it worked very well.
While a strict figure for the bench’s weight capacity is not available, a quick browse through their other stand and bench products shows a general weight capacity well above most other brands. As such, while we cannot say for certain that this bench provides the best weight capacity, it is more than likely that it the capacity is similar to the other products in the catalog.
