Sugihara bar dressing help?

[SbTVF]

Running an 18” sugihara pro solid on our tajfun 400 processor

 

It has a tendency to wear the rails on the left hand side (looking down the bar from the saw end) faster than the other causing it to jam in the cut. Struggling to even touch the bar with a standard Oregon flat file and dresser tool to square it back up because of the harder steel.

 

Any tips/tools to get a really square bar on these hard steel bars?

Yes the Oregon file is not very hard IME. I use regular Bahco file in one of these for dressing bars. Only dressed the cheaper Sugihara bars though  http://www.axminster.co.uk/veritas-jointer-edger-600304

How about a belt linisher/sander or a powerfile.

I had thought that. As long as it was on a bench one so you could guarantee sanding it perpendicular I should think it would work. We don’t have one but may be able to mount the big 110v makita belt sander on a bench to do the same job.

That what I would suggest . Also have  a look at what is making it ware unevenly ?

Check out the chainsaw guy on you tube, he has some interesting videos on dressing and fixing damaged bars.

Answers are there. Buy a better file or Belt sand it and as stubby said find out why it’s wearing unevenly. Reads like something is goosed

Our processor bar wears unevenly as well. I think it's just the nature of the work. When you have nearly finished the cut the log starts to lean before it falls creating uneven presure. You dont get that when using a chainsaw on a log on the floor.

 

Combine that with what must be thousands of cuts in day and it doesn't seem surprising that the bar gets a bit of uneven wear

The log comes at the saw from the right hand side and with the old Oregon bars the rails always burred out on the right hand side within about 20 cube.
Hence changing to the Sugi to stop that.
It now seems the bars are wearing down on the side of the bar where the log isn’t supported by the infeed belt. Not sure its an unreasonable amount of wear really.

The chain is kept tensioned as per the manufacturers recommendation.
