tractor sawbench cutting rough

[forestgough]

Anybody tell me about excess vibration when crosscutting firewood?

People tell me the teeth are probably different lenghths and i should hold a file against them while the saw is running,but this sounds dangerous.

Spin it slowly by hand then check them. File the high ones to even up. Check rake angle and set as well.

Presumably you have checked the bearings.

Sounds dangerous and stupid to me too.

Wouldn't be the best idea I agree. The ideas right but if the teeth are far out then it could cause all sorts of injury.

 

I would try and fix a pencil or marker at a right angle on the sawbed to come in contact near the tip of the tooth and spin the blade and try leaving a marker line on each tooth and try and compare them.

Its not something ive done but it may or may not work to give you an idea of the rogue ones.

This would work but all I used to do was use a piece of wood and spin the blade slowly by hand BACKWARDS. It doesn't snag or damage the blade and as mentioned you need to plck out the rogue ones. Check the things I mentioned previously as well as the height though.

Would not do it with a file but it is a trick of the trade using a scythe sharpening stone to identify the protruding longer teeth. Once identified sharpen as normal but using twice as many file strokes on the identified teeth. Repeat process every time you resharpen and eventually all teeth will be the same length. Personally I just send the blade off to a saw doctor and it comes back like a new blade.

What type of blade do you have on it?. Could be just getting blunt if its not clean timber. It should probably have something like what you find on firewood processors for crosscutting.

there was quite a good video on youtube and the guy uses a brick to hit the high teeth sounds safer than a file

It sounds like the blade may have lost some tension, we had tractor and diesel saw benches and it would start vibrating sometimes, and we sent them off to be fixed. I would not think the length of teeth would do it.

Does not cost us more than £30 to get a blade tensioned and professionally sharpened and missing teeth put on.
