Debarker
« on: June 13, 2016, 08:42:42 am »
My debarker arm has gotten sluggish. Everything is lubed and as far as I can see it has nothing out of place. To me it doesn't make sense for that spring to loose it's mojo that quickly??

Any ideas??

Thanks

The pivot for the arm can get really gunked up inside, especially if your mill lives outside. You have to disassemble it and clean it up, it may even have some rust on it that you will have to sand off.

Be sure to swing it in and out continually as you grease and continue to grease it to purge out the old grease.  I like to use a good high pressure grease.  Also, when setting up, always have the sawmill at least a half bubble high on the loader side.  You need the added weight of the debarker aiding the spring.  I also spray the spring/rod with "SLIP Plate" dry graphite.

I had to disassemble mine and clean out the old gunk. Use your enginuity to hang the debaker, it will save you a lot of time.  I used a block under the pivot arm and a ratchet strap.

Hello,
   If you pull the Debarker out of the pivot and there is gunk and sometimes even rust. I have a 1/4" bolt with a slot cut into the end. Thread a piece of sand paper and run it in the drill. Polish that top bushing area up and it should move freely.
Hope this helps.

Are you saying that you "grease" the alemite with ATF or that you do not grease the alemite at all?

So, I'm doing my homework on debarkers.  I know next to nothing about this, so please bear with my ignorance.  I did a bit of searching but this is the only thread I found that deals specifically with them. 

I suppose there are whole-log debarkers, but that's not what I'm wondering about. 

From what I gather, there are small debarkers that basically take a slice out of the bark on the side of the log exactly where the blade enters the log, to remove any abrasive material, so the blade doesn't get dulled by dirt, etc, on the outide of the log.  I haven't seen any photos or videos, so I'm summarizing what little I do know (or think I know). 

I have some logs that have been sitting on the ground and I'm concerned about milling them and hitting sand and all kinds of other grit.  Last year I milled one log that had dirt all over one side, so I wire-brushed off everything I could see.  After that log, the blade just wasn't the same. 

So if you experts can chime in, and especially if somebody can post a video, that would be much much appreciated!!

I'm thinking about what it would take to get one set up on my HM126 mill.

It's a quick fix for me on the job to put several shots of ATF on the debarker arm shaft when it slows down.  Just remove the 9/16 bolt on the bottom, use a pry bar to lift up the assembly an inch or so and squirt the ATF in there.
