Right next to the sharpening bench is my work bench. It's made of SYP imported from Texas, I used just under 400 BF of construction grade 2X12s. My guess is when completed it weighted about 400 lbs, having been in Arizona for over a year I'm sure it is under 400 now. Whatever, it does not move. The hardware is Benchcrafted with a leg vise on the left and a wagon vise on the right. I looked for wind and hollows or bellies the other day and it is still very flat.
There is not much I would change if I were building today. I have a 10.5" Paramo quick release vise made back in the 70s that I might use instead of the leg vise, it holds a little better than the leg vise but not enough to retrofit, or I might just stick with the leg vise. I would use round dogs instead of square, nothing wrong with the square ones, just no real advantage for the square dogs vs. 3/4 round ones and round make an easier build. I doubt I would install any end vise, wagon or otherwise. I knew going in on this build I seldom used an end vise but I thought maybe if it was a wagon vise I might use it more. It doesn't happen, nothing wrong with the wagon vise I just have work habits where I use other ways to hold my work that work for me. The Benchcrafted wagon vise is a fairly easy install compared to other end vises but nothing is a lot easier and I don't think I would miss having an end vise.
Odds are I would use SYP, this is my fourth SYP work bench build and they have all worked well. Having said that, maple would sure make a pretty bench and if I were to build another it would be because I just wanted to build a bench not because I needed one. This bench does every thing I need it to do and does it without compromise. If I did build another, one would have to go. There is not room for two just under 3 meter benches in my small shop and I'm not sure I could work on a maple bench like I do on the SYP one. When I spill something or nick it I know it is just a work bench, a maple one maybe not.
