Matt, Seems that Joe wanted that piece of 1/4" x 3/4", but not clear after his last email. If Joe takes that there wouldn't be enough for another piece. The back is too heavy for a 12" - 14" saw, IMO, is why I feel 3/16" (not 5/16") would be better. I made an 18" saw and used that back, it was actually 1-1/2" wide and I sliced it down the middle. That saw I used a .032" plate on. I wouldn't use that thick of a plate on most of my saws, but that was a 4" plate. It's all a matter of preference. Disston used thick plates. In modern times people are using thinner plates, some of them too thin. On small saws they are using .015", and I think that's too thin over the long haul. Some of it is just appealing to the people buying saws. Half of them read Schwarz' blog and run out buying what he reviews. That is when he's not selling his $25 DVDs... Sounds like Ray has you covered on the 1/4" backs.
