I scored a nice 14" bandsaw a few years back and find it to be one of the most used power tools in my shop.

One thing that has bothered me since getting it, is the nick the weld from the blade puts in the wood on every revolution.

Some blades are better than others (and I've tried a few.)

Do any of you band saw users have a solution for tuning the blade to get rid of that one little bad spot on the blade?

Thanks in advance,

Dave

You could try filing or grinding, but a blade for a 14" saw is not worth putting much time into. If it's not brand new, replace it. Blades are an expendable supply item.

Nick in a weld? That's abnormal. Like Howard suggests carbon bands are very cheap.

On the other hand, if you have time how 'bout a photo of the weld? Band widths including welds are narrower than the kerf and should not be making any sort of contact with the sidewalls after the swarth is gone. If the weld is not straight the test is hold the band pinched together in a figure 8 shape. If the weld is good the band will be parallel, but if it's bad the band will bow. A bad weld will cause the band to pulse when it's running. Other than that I can only think of a crack causing a problem.

You could get your blades for a reputable dealer. You shouldn't have bumpy welds, that is not right. I suggest
Hastings saw in Rohnert Park. Most everyone for miles around buy from them. They ship everywhere. They do a great job on welds. I know there are others around the country. I like Lenox bi-metal blades myself.

I'm with Larry. I have a 14 inch bandsaw in my shop that gets the doodoo worked out of it. I have to tell you though...I have never noticed a problem with the cut as it relates to the weld. There shouldn't be any 'nicks'.

Thanks guys,
I think the best description of the issue is that the blades pulse at a given spot with every revolution. I'll try the file trick and see if it helps. The last time I did that it threw enough sparks that I was afraid of starting some sawdust on fire. I'll just blow it out REALLY good before putting the stone to it.

If you can only HEAR it, I'd say that's normal. (I've heard that pulse with, I think, every blade I've put on my 14".) If you can SEE damage the weld's causing (although I'm not sure how you would pin this down), that's not.

Are you sure the weld is causing the marks you are seeing? My experience (I'm still
searching for the perfect set-up) is that the teeth leave grooves and ridges along the
cut, depending on how steadily I feed the wood.
