To minimize the bandsaw blade wear & tear, we have a debarker unit attached to the head-rig of our bandsaw mill when cutting Northeast hardwoods (i.e. oak, maple, and ash). This debarker is a ¼ inch thick circular saw blade with carbide tips from Woodmizer.
When cutting a log, the debarker blade actually cuts a slit along the bark at the same height as the cutting blade, thereby minimizing the wear on the blade from cutting the bark, when entering the log.
Is it useful to have 2 debarkers on each side of the log cutting slits, so that the band blade would be free of bark on both ends of the log?
I would say a second debarker would do very little if anything to extend blade life. The teeth of the blade when they enter the log would find debris like dirt very abrasive. When the teeth exit the log debris would have no affect on the blade so long as the debris is no longer on the blade when it re-enters the log.
Shaun is dead wrong about this. I have often thought about adding a second debarker on the backside of my Baker 3630 E. Frozen dirt or embedded grit or rocks will dull your blade as fast on the back as the front. Steve C.
I bought a Baker 3638d about 13 years ago. I ordered the debarker on it , as well as the computer setworks. It "was" portable also. The debarker was completely useless and a waste of money. The blade was to small to cut deep enough on thick bark logs like Doug Fir and Incense Cedar, and wasn't powerfull enough for a bigger blade. Hopefully they have solved this problem by now. For many years now, any dirty logs either get peeled if the bark comes off fairly easy, or pressure washed, before they go on the mill. For me, it's worth the extra time, as I have a small market for the clean slabs. I think Steve has a point about frozen debris on the exit side of the cut. But if you are putting logs on your mill full of frozen mud and rocks, how long do the blades on the debarkers last? Just a thought. By the way Steve, if I may be off subject for a moment, how do you like your electric mill? When I bought my diesel mill, I wanted to be portable. I found out early on it is way cheaper and easier to bring the logs to the mill. I wish I had the electric mill now ( I think)!
I think I agree with the first Shaun. The reason the debarkers are on the enter side is so the debris does not get pulled into the log creating abrasive residue. When it passes thru the other side, it usually gets thrown outward.If you are worried about debris on the back of the log going around install a blade brush. I'm sure it will be a whole lot cheaper.
