I've long been in search of a bandsaw blade that cut smoother. I've known about the carbide toothed blades but those don't usually work with 14" band saws. Recently I learned about Trimaster blades 1/2" 3 T.P.I. and the blade is .025" thickness, same as common 14" blades. The only source I could find is toolcenter. Finally convinced myself to part with $160 for one. I ordered it March 3, shipped March 4 and got it March 6, not shabby considering it came priority mail. I'll post pictures at the end, I can't figure out how to put pictures in the middle of a post.
Of course like any other kid I immediately had to try my new toy out. I removed the 1/2" blade already on the saw and mounted the Trimaster. Very little adjustment required, I just cranked the tension up as high as I could turn the knob easily. I was concerned about collapsing the spring but no issue, there was plenty of space between the coils. Set the fence for about a 1/4" cut, found a piece of Poplar scrap and hit the switch. Oh my, where have you been all my life? Fast (considering it's a 1.5 h.p. motor) smooth and no drift. The vertical stripes look more pronounced in the pictures than they are in person. Couple passes thru the drum sander and good to go. Okay Poplar is soft, let's try Red Oak. Same result. I generally feed resaws pretty slow, I find it leaves a little smoother surface and takes it easy on a small motor. The widest piece of scrap I could find was 7 1/2" but put a straight edge on it and no detectable barreling. I LIKE IT!
I bought a Diemaster 2 at the same time. That isn't as happy a story. It drifts. I checked the saw and adjusted the lower wheel a little so the band ran in the center of both wheels like the manual says. Still drifts. I have a new Lenox flexback 1/2" X 3 T.P.I. and mounted it. No drift so need to spend some time on that. I did try a point fence with the Diemaster 2 and it cut pretty well though not as smooth or fast as the Trimaster. I'd estimate the drift at about 5 - 7 degrees. The last picture shows the Diemaster drift.
Executive Summary: A Trimaster 1/2" .025" 3 T.P.I works well on a 14" steel frame band saw.
