I am new to using a bandsaw and have some issues. I have a rikon 10-345 the 2.5hp model. I have a 3/4 inch woodslicer blade and I am trying to cut a 7 inch thick and 2 foot long elm log on a sled. I cut about 5 inches into the log then is just wont push through any more, it is like stuck. The blade is still going but I can push the log through. I can push with a little added force and nothing happens, it is kinda hard to push through to get it started but not as hard when a few inches into the log. It’s like I hit a wall. I have my guides close to the wood and the bearings are close to the blade without touching unless small pressure is added. I have the belt set on high speed and tried it on low also, no difference. I tried giving it a little added push but I had to use enough force that I accidentally knocked my blade off the wheels (I have a little kink in my blade now where it got a little bent but it is minuscule). I have the tension set to about a 1/8th to 1/4 inch deflect when i push on the side. I don’t know what is wrong. The blade doesn’t bog down or stop, it still going normal but the wood just won’t push through. I have noticed my blade has a flutter to it also, and looks like goes forwards and backwards a little (1/16th of a inch maybe at most).

You are probably using the wrong blade for re sawing.

Are your using any dc? If not you will want to temporarily ease off your feed rate to allow the dust you’re creating a place to escape.

Do you have any burning?

If you try to force the wood through you can end up with a heated blade that will never cut right.

My personal guess would be a dull blade or improper feeding .

I don’t have DC, no burning, and the blade is new, used it less than 10 times.

Couple things that come to mind is the elm dry?Wet woods need blades with a lot of set.
Second is something catching on the throat plate I have had rough woods snag up on the throat plate.
Or the blade is too far gone I think it’s the woodslicer blade that starts cutting wonky when it gets dull.
Sorry that’s all I can think of from a thousand miles away.Aj

When feeding a log/wood through, if you feel like you aren’t gaining any headway through the cut back it off a 1/16th to allow the sawdust a place to go and feed it through again.

Wedges on the outfeed side will help the wood to not bind.

Sure the blade is not on backwards?
I assume the other ten times you used the blade it cut okay.

This is a tough one, Michm can you post some pictures of your operation and different angles? Not in operation but with the sled setting on the saw, the blade and the saw it’s self also the log you’re trying to cut.

Elm is very twisted and splintery. Have you tried another log/species?

I can’t help but wonder if the sled isn’t getting caught on something. Usually when I have an issue where the blade is wandering through the wood, the saw will always bog down when pushed harder before anything worse happens.

It sure seems like something is snagging on something.

Can you make a clean pass with the sled when there is no log on it?

Have you tried stopping the saw at the sticking point and taking a closer look at what is happening?

Maybe you hit a nail and dulled the blade??

Your insert (round thing that surrounds the blade, set in the middle of the table) is lower than the table. Happened to me before. Scratched my head for a second and then it dawned on me what was happening.

I am not going to be at home today but as soon as I can I will check on some of the things you guys mentioned and take some pics. After I couldn’t get it to cut right I just started fooling around and started to wedge the log trying to get it to split. I was just cutting the log to see what the inside looked like. The Elm is still green, and I think it is very moist because it is heavy for its size. I think my blade is set up right but I will take some pictures. I don’t think i ever hit a nail, I have cut other wood and logs and never seen any sparks or anything that would make me think I did.

I watched this video and followed this guys advice for set up of the bandsaw. https://www.youtube.com/watch?v=wGbZqWac0jU

I’m thinkin either your sled or the log is hitting something that stops it. Maybe raise the top guide bearing assembly? If your sled will glide through without the log, the log must be catching on something.
