14"bandsaw with Timberwolf blades

[Vince Welch]

I have a Jet 14†band saw with a 6†riser block. I am experiencing a problem and hope you can help.

I just replaced a blade because it got caught while in was in the middle of a cut and kinked ruining the blade. So I replaced the blade with a new blade and I am experiencing the same sort of problem. When I cut small stock of wood (2-3â€Â) no problem! But when I cut wood 8-10†there is a banging noise. The wood is seems to be getting slammed into the table and occasionally the blade stops/get caught or hung during the cut. I have checked everything on the saw and everything appears to be in correct position. I wonder if the tension on the blade is correct? I have loosened the tension until the blade vibrated slightly then tightened it up ½ turn. Still the problem continues. I need my fingers and hands and do not wish to have an accident. Any help would be greatly appreciated. Vince

Vince,

Is the wood supported on the bottom of the wood thru the whole cut? The size of the wood doesn't matter, it sounds like the wood may be up in the air a bit then catching on the blade and slamming into the table.

Another potential problem is a rounded piece of wood (i.e. log). If it rolls, it can roll into the blade and cause a catch + kink.

Recently I was cutting unsupported wood - a little piece. To fix the situation I ran the small piece thru the blade with a waste piece of wood underneath to provide better support. (But of course that was after I kinked the blade).

If the insert on your bandsaw is soft or not complete supported, that can also cause problems.

Something is grabbling wood

I agree with Jef,the wood is being grabbed and then slammed down on the table. Sounds like its not only not supported,but perhaps the wood is trying to turn too. I lost a good Highland "slicer" (30$) to a viscious grab and subsequent kink. I would recommend the following: Tighten the heck out of the blade,support the botton of the work,insure the wood will absolutely not turn any! Feed with the drift taken into consideration. Something will work,besure your hands and fingers are not in the way. JMHO Paul W

All,
The results are in and the winner who stated the correct fix to the issue is..... The pulley belt was too loose pulling the motor up then releasing it creating the slamming sound that I was trying to describe to you. Once I had two additional hands in the picture I was able to tighten up the motor and belt. Final result, I cut an 11" cherry log like butter with a new blade on the saw. No slamming or noise! I thank everyone who stepped up and offered advice and their experience. It is what makes this forum helpful, comical, and truly unique. Thanks again, Vince

Tighter??

I would recommend the following: Tighten the heck out of the blade,

Not long ago I would have agreed. Recently I read an article in Fine Woodworking (within the last 3 issues, don't recall which.) The author outlined bandsaw set-up methods he used. I followed his guidelines and my 60+ year old 14" Delta cuts better than at any time since I got it, 25 yrs. ago. You would have thought I could have figured how to use it on my own in that length of time.
