A Hot Mulberry

[bck]

I tried several times last night to saw a mulberry on the sawmill and each time about one or two feet into the cut the blade would take off up or down.

Got tired of messing with it and decided to cut it into turning blanks. About 5" into the first cut , without warning, the polyurathane tires on my grizzly bandsaw melted 

I havn't had a problem with anything else,I cut a locust the other day straight as an arrow. Wont expecting this mulberry to be a problem? Anybody had problems with other logs?

I had a similar problem few years ago.  I had just finished rehabing a vintage Delta bandsaw complete with brand new polyurethane tires.  First cut with a brand new Delta band and it quit cutting after just a few inches.  I turned off the machine and the band promptly melted it's self into those brand new polyurethane tires.  Problem was the brand new band had zero set.  I suspect your problem is a similar nature...possibly a dull band, or a band with too many teeth.  Mulberry taint that hard too saw.

And a plug for Delta service...I called them with my story and they sent new tires, and bands at no charge with expedited delivery...and no questions asked.   I found out later Delta's bands come from China ...switched to Lennox.

yea, I wasnt expecting it to be hard to saw but it gave two different saws a hard time??  ??? ???
I tried to put pictures up but could get them no farther than the photo album-gallery. I clicked the " upload or insert photo? "  button then uploaded the pictures . But had to chose an album to put pictures in??? and cant figure out how to get pictures from album to thread.

Like this ???  ;D ;D

 

  Once you have a photo in the gallery, click ON THE PHOTO. It will enlarge in a new window. Scroll down, until you see the IMG tagline, about the photo. I highlight and copy. Then, go to the post and click then paste that code. Nuttin to it, EH ???

  After pasting the code, space 2 clicks on enter, then add the second or more codes for more photos. This leaves a space to keep the photos from running together and hard to read.

Thanks for the directions Fla_Deadheader

It just dont seem right for it to get that hot that quick into cut. The picture you showed has the only burning, the other side is clean. Never smoked to warn it was that hot?  I have cut oak and locust with these saws recently with good results. I believe this mulberry is haunted  :D

I have only seen burns like that one time, and it was eastern redcedar.  Well, actually it weren't the ERC that caused it to burn, it was the barbed wire nailed to the tree many years ago that caused the problem :

Had a guide on the sawmill that was out of position some, adjusted it and cutting straight again. Found a blade speed calculator and realized my blade speed is probably to fast at a little over 7000

Melted tires still got me puzzled though  ???

Doesn't take much rubbing on the blade to get it HOT. That's why you melted the taars.

Also band slippage will heat the band and tires.  You might look at tension and see if it is sufficient for your band.
