Ok I am really new and have a new bandsaw my first bandsaw…. I set up the bandsaw with blade and did some test cuts with the stock blade all was fine but I wanted to put on a timberwolf 1/4 in blade and try some scroll work well I put the blade on the saw and tension it at best I can by the instructions and set up the guides as best I can the blade seems to be tracking fine so off we go to cut out a small riendeer like the one I have on my projects page.

This is a pin 2×4 and the saw is a powermatic 1.5 horse 14in saw. So I start to cut get about 2” into the project and the saw jams and blows the breaker…. so I turn off the dust collecting thinking it was just and overload and try and start the saw again … blade doesn’t move….breaker blows…. after unplugging the saw) I look at the top wheel and it seems to be fine.. blade in the middle no issues…. well then I tried to open the lower door to check out the bottom wheel and it is stuck I mean stuck stuck so I completely detentioned the blade and then pulled the door open harder… the tire was stuck where it had melted onto the top of the door. and this is what the tire looks like after pulling it off the door


now what did I do wrong? any ideas??

I’m really no expert, you can take that to the bank, but I would say your wheels need adjusted. Would be interesting to see how much space there is between the top of the top wheel and the bottom of the top of the cabinet and compare that to the space there is between the top of the bottom wheel and the top of the bottom cabinet. I would bet there’s a big difference between the two measurements.

Sounds like a tracking & or tension problem. If the blade was tracking well & the tension was OK then this should no happen but it will usually occur on the top wheel. Check the bottom wheel for stability, it might have a wobble, the bearing could be done in.

It may be an adjustment issue with the lower wheel. It could
be sloppy manufacturing of the cabinet.

I would take the door off and pound a crown into the door itself to give
wheel more clearance.

Your tire may need a little correction too, maybe not.

well to be honest as I said I am really new to this so I might have botched the tensioning ….. this is a brand new …. 1 week old powermatic saw and with the stock blade it seemed to be fine… I am sure I screwed up the setup of this blade somehow…... or maybe I didn’t fully close the bottom door and jamed it uner the stop…. I really don’t know…. am going out to check the wheel now …. ok I went out and checkedthe wheels and they are solid can’t wobble them the whole saw moved not the wheels tho…. I think it was user error pure and simple… the bottom door must have been closed improperly…...pics in a few

I tend to agree with Grumpy and suspect that it is a tensioning problem. When I set up my saw I found Marc Spagnolo's bandsaw tuneup video very helpful. It is episode 13. I have the same saw and I installed it in December and haven’t had any problems with it.

But what a bummer. With all the problems that you have had getting the saw in the first place and then have something like this happen. That is a real letdown.

Keep us posted on your progress.

The ribber tire might have come off the wheel. If it was not installed correctly it might have moved off to the front.

What kind of guide blocks/bearings? Maybe they were too tight and heated the blade?

lew…. coolblocks on the upper guides and bearings on the lower guides the blad was not touching the guides…. I really think it was a combo of the tention not being right and me not closing the door properly…..

Scott: yeah I had a few moments of what the hell did I get myself into… maybe this isn’t for me… but then now I have calmed down a bit and I just have to be more carefull and that I have a learning curve, it was something I did wrong and now I have to learn from the mistake and figure out what I did….. I have watched the video on bandsaw setup on the wood whisperer good stuff I enjoy his webcast stuff much more then either Norm or David Marks but then he is also closer to my age then those guys….

owell I will head to woodcraft tomorrow and pick up a new tire and talk to thier bandsaw guy(sometimes I am a visual learner) and see if he can show me what I did wrong.
