Topic tags/keywords: bandsaw

Hi,

I am new to woodworking so I do not have a lot of knowledge yet. I have just purchased a Ryobi 9” Band saw mainly because it was cheap and I am on a strict starter budget. It came with a 1/4” blade on it that worked pretty well on a few band saw boxes I tried but I heard you could get tighter turns with an 1/8” blade so I went out and bought a decent one not a real expensive one. I followed the changing the blade instructions and also watched a few videos on how to change one on YouTube before I changed it. I got it to track in the middle of the wheel like the instructions said to do and put the guides where they are recommended to be but every time I try and cut through something the blade pushes back behind the two side guides and to the side of the bearing wheel. I tried adjusting the tension but it didn’t seem to work. I don’t know if the blade is bad or what. I have limited knowledge. Any help would be appreciated.

1/8” blades cannot ride between the side rollers/guides. They must be set to work with the rear guide, and properly tensioned to work without the support of the side guides.
The exception to this (you knew there had to be one) is when you are using soft side guides such as a wood or phenolic block. These guides can be set to cover the sides of the blade (think pinching the blade between thumb and forefinger).
Crank up the tension little by little while you run some practice stock through the saw.
Good luck.
Bill

Could it be that it is put on backwards? The teeth should point down. Otherwise, it is normal for the bearing wheel to turn.

Keep turning the top wheel by hand; adjust the tilt until the blade tracks in the middle.Turn it on and make sure if it stays there . If you’re satisfied with the tracking, set up your blade guides. You can use a paper bill to set accurately the distance of the blade and the guides. If the blade is damaged, it won’t track well ; most likely jump off while cutting and you better start with new blade and set up everything right from the start.

Did you also set the thrust bearings distance correctly?they are the one that prevent the blade from moving too far back,I think you should start from scratch to set up your bandsaw just like surfside said above,loosen the tension on the blade ,make sure the upper wheel is not tilted,move the thrust bearings/guide blocks back,then increase the blade tension. Turn(by hand) the upper wheel counter clockwise while adjusting the tilt so the blade tracks in center of the upper wheel,then setup the bearings/guide blocks.

I agree with Ken. The thrust bearing should be adjusted to keep the bade from getting pushed back during a cut. Unless this little Ryobi is designed differently from all the bandsaws I have used.
