It actually didn't leave a visible mark but I am currently hard down. This evening as I was finishing up resawing some beams for a customer and my debarker ... just fell off. :o I hadn't even used it today. It was just hanging out there out of my way. Then while dragging a board back it just dropped off. It looks like the pin that the assembly pivots on is broke in half. It was getting dark so tomorrow I'll take a closer look but it appears the pin is welded in place to the support arm that holds the debarker. I've sent Marty Parsons an email and some photos and I will follow up with him in the morning to figure this out. I'm just glad I was milling at home and not out on a portable job.

That's an odd thing to happen!! Will warranty cover repairs? :-\
Is that something along the lines of a 1"+ steel rod that sheared off?
Could you post pictures of the failure point on all pieces involved?

This is a close up of the swing arm that holds the debarker. The round gray area is the broken shaft/pin.

This is a close up of where the shaft/pin is supposed to be attached. It broke off up inside the assembly and dropped out.

In picture number 2 I can see the beach marks. Probably a nick or a weld stress in the pin started the failure.
I hate it when that happens.
can you not just disconnect the cannon plug and continue mission?
it looks as is it was a fresh brake, no signs of corrosion, indicating a crack prior to failure. as if it literally just broke for no apparent reason.
I wonder if that arm wasn't swinging freely (binding) and causing the circuit breaker problem?

It seamed to move OK. I greased it and I could push it out of the way when changing blades.
I broke mine there in the 1st month I had the mill. My mistake, I was putting the head in it's travelling position and forgot to swing the debarker into position, i dropped it onto the support leg. I was sent the next revision debarker arm. I installed it and still found the debarker does not swing quite enough to saw those big ugly logs, it was 1" inside the outside bearing so I could only saw 31" wide. I have now got rid of the "V" that controls the swing of the debarker, I can swing it all the way past and actually saw close to the 34". I can also swing the debarker to 180 degree to change the blades.
I used to swear at that debarker every time I wanted to change the blade or try to squeeze by a bump.
I also now move the saw head to the far end to change blades and am able to swing the debarker all the way out. Just have to be carefull that I don't swing it 360 degree as the wiring starts to wind up. ::)
Good thing you were not using it when it fell off. That would have really left a mark with the blades turning.
Good News. I'm not the first to have this happen. It's covered by warranty. 8) And, the new, revised part is on order.

I know what you mean about the "V" but I've not had the need to saw at 32" yet. I have been changing blades at the far end of the mill for some time and compared to the old non-wide version of the debarker it is some what of a PAIN to work around. I've banged my head a few times. ::)

Thanks for the pictures.
Can you tell if that was a machined pin or was it a cast or forged part.
The last part I saw that looked like that was a poor quality forging.
