Before ya'll start bashing Woodmizer and favoring another saw company, maybe do a real good check of your mill setup. Sometimes alignment problem aren't obvious until you start trying to cut wide boards. What lube are you using?

Even WM states using too much lube in dry wood will cause the wood fibers to swell and rub the blade more, causing friction. I have found the same myself. I was once cutting a very old, dry walnut log. I was having to saw very slow, and I thought it was a matter of not enough blade lube (water and soap). Cranking it way up didn't help. I found a sweet spot, just enough of a drip to keep it clean and lubricated, and I was able to cut as fast as normal without excess blade heat. Also note, excess blade lube will soak the sawdust in the gullet to the point where it is no longer carried out of the log, but sticks on the cant/board.

Not blastin WoodMizer love my little saw. The problem is most likely a loose nut holding the speed control. I an just tryin to figure out what I am doing wrong. I have wished that I had named this pos Help blades getting hot in wide cypress. I don't want to ofend anyone and I will keep using WM BLADES. Might just be a diferent wm blade.

Cypress Sam ...

Starting at .030/.032 you should be in good shape. I've run more set depending on which mill I was running at the time, what I was cutting, and which blades I was running.

I did think about this overnight though. In your original post you mentioned you didn't have trouble with your Lumbermate making these cuts and that did bring to mind possible speed differences. Whether it's blade speed or feed speed.

Don't feel bad. You can get your mill to saw straight and cool, even in those big logs, and even though you might not have the horsepower a bigger mill does. Once you get your blades set up right you'll be in good shape. We'll be pullin for ya. ;)

As all mills are basically the same blade speed is the only difference I could figure between his Lumbermate and WM and that sure is not saying to get a Lumbermate , I,d try a smaller drive pulley on the WM. With higher blade speed you have less torque at the blade and will lug the motor sooner most likely resulting in slower feed rates causing heat. Cutting smaller logs the higher blade speed will cut faster, it's a trade off just like chain saws. Most every time I gear the chain speed down a saw will cut faster in big wood while losing a bit when limbing. Steve

Man ... don't go changin' drive pulleys. That WoodMizer will cut just the way it is designed to. Make sure your drive belt is tight enough so you're not getting any slippage, put a razor sharp, well set blade on there and don't feed it too fast. You should be good to go.

It sure isn't going to hurt trying a $50 or so pulley, you can always put the old on back on. My blade speed is quite a bit slower after I put the diesel on my mill with the same pulley as the 3600 RPM gas motor had vs the 3100 RPM diesel, It saws about twice as fast with the diesel . Steve

Only got to cut one 14" cant. Blades did fine. Now I am cutting 2x6 to make t&g for a timber frame roof sheath. I will have to wait untill the next order to see how the new set works out on some larger footage.
