Could this be a blade problem?

I’m setting up my new Rikon 18” bandsaw. I’ve gone through all the adjustments according to the Snodgrass video. I think it’s the Woodslicer blade although I can’t be sure as there are no markings on the blade. I wouldn’t call this drift, more like dive left. The photo shows the problem. I can literally see the blade dive left at the very beginning of the cut, about 3/4” into the cut. It’s a 6” piece of Claro Walnut. I have a new Timberwolf blade standing by but it’s a PIA to pull the fence and the table to get all set up. I don’t want to do that again only to find I have the same problem. Any advice?

This usually happens when your blade tension is incorrect. The idea is that when you tap the blade with your finger, it should have a movement of slightly less than 1/8”. If it doesn’t, its too tight if it goes over 1/8, it is too lose.

Tension or the blade is way too far forward on both wheels and instantly flopping whichever direction offers the least resistant when starting to cut.

Thank you for responding.
I went through the set up again. I did have the blade too tight and the gullet was about 1/8th off center (towards the front) The gullet is now in the center of the tire and the blade moves about an 1/8th of an inch when I tap it with my finger. But it hasn’t changed the cut at all. Still diving to the left as soon as I start the cut. I can see the blade twisting as I start the cut. I called Rikon but there tech guy left for the day, he’ll call me tomorrow morning. Any other ideas?

I guess it could be the blade if the set on the teeth is wrong, or not the same on both sides. Do you have any other blades that you can try?

Dull blade. One way to help this blade a little is to put a sharpening stone to the side of the blade while it is running. I have found this to help straighten out the cut on a bad blade. If this helps you will know it is the blade that is bad.

Did you set the guide blocks correctly?,(gap/height)if you did ,then your blade is most likely dull,try another blade and see how it cuts.

Even though I’ve had and used my 16” Grizzly bandsaw since 1996, I’m pretty inexperienced with band saws at this point. I’m planning to get a lot of experience in the near future. I cringe when I think about putting a stone against the side of a running blade. I’ve seen the recommendation before. It sounds dangerous to me. Maybe when I get a little more experienced I’ll be more comfortable with that. I still have all my digits after 22 years, although there have been two trips to the emergency room, both left numb fingertips on two fingers on the same right hand. It’s a constant reminder and a PIA when to get something done your hand must align or start something but you can’t see “the work”. (Think starting screws, bolts, almost any fasteners, plugging in lamps behind the sofa….. I digress. I’ve only had two serious accidents in my 25 years of woodworking. More than I expected but plenty enough to cause me to be really cautious for the rest of my woodworking life. Am I over reacting?

I’ll try another blade tomorrow.
Thank you all for your guidance.

Ken, there is nothing wrong with being cautious; especially when it comes to your flesh. Sometimes you have to hold a thick board at an angle to cut it straight on a band saw.

Resaw a 2×4 by hand and watch the angle to see. The blade may
be just leading like crazy. Assuming you have your guide blocks
far enough forward and set tight enough… well, a 1/2” wide
blade is not really wide enough to cut straight without guide
block support.

Assuming you followed the Snodgrass method and have tensioner the blade correctly I seriously doubt that is a woodslicer. The kerf is very wide not to mention the dive. I would try the TW assuming it is new and sharp. How is the vibration when the saw is running? With a kerf that wide there is something amiss. Is the blade fluttering ?

Jumbojack, good observation I’ll switch the blade out tonight.

Blade width is also a factor in drift when resawing thicker materials. A 1/4” blade always seems to drift in thicker material.

Blade tension, tracking, and sharpness are factors as well. I NEVER cut curves with a blade I intend to resaw with.
