I just bought myself a second hand SIP band saw, when using it for the first time today the blade jammed and from then on the saw wont cut straight I've looked at the manual and played about with the guides but still no joy.

Any advice or tips welcomed.

Thanks Paul

Not having a bandsaw I may be well of the mark but when it jammed did it damage the blade

hi Paul

if you have got a new blade put this in and set the guides up as instructed by the book not forgeting the ones that run behined the blade as they should all be set at a papers thiknes wider than the point of the blade that was welded or this will jam the blade. then try this hope this works if not you may have a problem with the bearings on the drive wheels

Hi Paul,

I would strongly recommend the Steve Maskery DVD called [url=http://www.workshopessentials.com/shop/index.php?route=product/product&path=35&product_id=53]Bandsaw Essentials[/url].

It'll take you through everything you need to know about setting up your bandsaw.

Thanks,

Neil

Hi Paul, if it wont cut straight then it is, as Derek hinted, it is the blade. I have a Metabo and on the whole a good saw, but I found that the best blades were from Hamilton Beaverstock.

There are a few things on a bandsaw that need to be right, as Dennis says check the guides, the side ones should run just behind the teeth of the blade, and the rear one a fag paper behind the blade, dont forget that there are two sets of these, one beneath the table.

Check the rise and fall and see that it does not push the blade to one side as you raise it. You may need to check the plate on top of this as it adjusts for any inaccuracies in the welding.

Make sure that the blade tension is right, as tight as you can and then back off a couple of turns.

Check the tracking, there is a knob of some sort at the back, turn the top wheel with your hand and adjust the tracking so the teeth of the blade runs just clear of the tyre, other wise you willblunt one side of the blade which will set the blade off on a cut of its own usually to your right.

Think why the blade jammed, was there any thing in the mechanism, or was one of the adjustments out, a slack blade will come off.

Best advice, spend a tenner with a decent supplier of blades and fit it, being careful of all of the adjustments, you will do it quicker with practice!

Glad everything’s ok now. It always helps to ask questions from different forum sites in solving our machine’s problems. I do that from time to time. If you get a chance, go to www.bandsawblog.com. I have found many answers both to my simple and complex band saw and saw blade questions from their informative articles.

It also helps to ask questions from the experts from different forum sites. Recently, I found a thread regarding best band saw advice. That was very helpful for me.

Hats off to the founders and contributors of the sites!

Thank you for the link you posted George. They’re very informative. But nothing beats experience. Remember the saying “experience is the best teacher”? Newbies become experts because of experience. Just like what Bruce posted, experts’ advice are reliable source for answers. I hope experience will teach me how to become a fine expert.
