I saw a Goat debark a whole log and that is the truth!  piston-smiley


I know paper mills have peelers. Can make a log slicker than a whistle. But I've never seen a homemade one.

Spinning chains ??  Maybe like a flail mower? 

Which just might work, if one can control the roll and flow of the log along with the rpm of the flail.

Yea I might help I was thinking to have a troth with a a dual chain turner for the log, and have one of those plow truck chains that whip the ground in front of tire to break up ice, powered by a hydraulic motor, mounted on a rail that goes back and forth via a chain system, and a diesel engine powering the whole setup.

i would think a rosser head setup would work better than  chains. you could probably use the same drum or what ever the chains are on and just replace the chains with homemade teeth or short spikes. we used to run one that was so old and patched up it could almost count as home made :o :D :D :D

I don't think chain flail would be simplest answer to debark a log. I am familiar with chain flails on chippers to remove bark and limbs during whole tree chipping. As you would expect during the winter the flail will remove a lot of small limbs and not so much bark. That being said, I am sure the design would be different so the results would be different.

I suspect you could pick up a Morbark Debarker at a sawmill auction far cheaper than you could ever build one. I know from years of experience, that a log debarker is the most abused piece of equipment in a mill operation. They take a terrible beating. Its not something you can just throw together.  Remember, every single log is different from the next. large, small, crooked, hard, soft, bark comes off like chips or it comes off like binder twine.  I know far more people that have been hurt by a debarker than a sawmill. That is another consideration.

Years ago the manure spreader of choice around here was the chain type flail barrel spreader.  Just a round trailer body with a large opening on the right side and a large pipe in the top middle with many large chains.  Spin it up and the brown gold had nowhere to go but out the side.  They worked great but when you started losing chains they ended up in the field for the next machine to pick up (bad news) and it would start to self destruct from being off balance.  Now you see many of them converted to wood trailers with the classic round barrel bottom.  Find one used and complete and it'll be a heck of a start toward a chain type debarker.

It's gotta be easier to have a long floating arm that follows the log contours as the log is being turned like you see in some of the commercial mills.  Building the live table I think would be harder, for the feed and turning of the logs.

You can buy mill hogs off ebay cheap That should last for a while.
That should be great for a home made unit.

I agree with Jeff. Unless you have a lot of high grade junk and a machine shop, it's almost certainly going to be cheaper to buy a used debarker. I've been thinking about debarkers a bit lately. Phase four or five of my sawmill operation will require one. Fortunately, I'm still on phase two. :D

something else to consider is speed a debarker has to be fast and do a good job or it will cost more than just sawing without it :)

I saw a hydraulic debarker working in a pulp mill many years ago. It was a ring of high pressure water jets and the log passed through (at about the same speed as a bandsaw carriage). They ran the water and bark through a screen, fed the water to a settling tank, and then filtered it for re-use.

A few years ago a contractor wanted a funky handrail for a deck and stair combination. He found a small diameter Douglas-Fir that had a lot of sweep in two planes and he was going to build the deck and stairs to match :o. He came to me for advice on how to debark it.
I told him a drawknife would do it. He told me it was way to slow, so I suggested a pressure washer. He tried an 1800 PSI electric and all it did was clean the bark. Then he tried a 2400 PSI gas unit that his neighbour owned. That just cleaned the stuff that he missed the first time. I suggested he needed way more pressure than that (notice I let him tell me what wasn't working before I made the suggestion)

Finally he rented a 3200 PSI gas powered pressure washer and that did the job nicely. In fact, he said he had to work quickly or it would start to tear off the sapwood.

So ... could you make a log handler that would feed a log past a pressure washer?

The one mill I have hauled to has a wheel that looks like a feed roll on a processer head . It is electric driven and set at some angle . The log turns and advances past the cutter wheel . seems to work well on 16 ft red & white pine .

Interesting....was that a steam unit?  It's definitely possible...but during the winter time I wouldn't be able to use it, and the ground where I am setting up is clay and doesn't need any more water!
