I made a simple circle jig for my band saw and it works great for thin stock but when I try to cut something thick like a 2×4 it pulls the blade sideways when I feed the wood into the blade. What am I doing wrong thanks

How wide is your blade? For small circles use 3/16th blade or a 1/8.

-- Live to tell the stories, they sound better that way.

Same issue last night. Using my 1/2” resaw blade. Works great on thin stock and even 3/4” MDF. Tried it on 3/4 plywood. Nope!

Thanks.

The center of the pin must be aligned with the leading edge of the teeth….............. Jerry (in Tucson)

Karda, I just made one last year, and until I figured it out, I had the same problems you are having. If you aren’t centered properly, it won’t cut your circles without a lot of binding…....... Jerry (in Tucson)

How are you supporting the wood to the left of the blade? If I understand your jig design, the dowel is the center of the piece you are cutting. So, that piece extends some distance to the left of the blade. If it is not supported, it may be tilting down toward the band saw table and pulling your blade with it.

Note the circle jig I made, which can be seen at the link below. Note the plywood extends all the way to the support shaft. This does a couple things: 1) It causes the sawdust to be carried down into the dust collection system, rather than dumped on the table and in the air; and, 2) It offers support for the wood being cut and to the left of the blade.

Bigger wood, bigger blade

I vote for Nubsnstubs’ idea … probably the location of the pivot.
Starting with a work piece flush up against the blade could also be a problem. Try cutting into an oversized work piece. Another words get wood on both sides of the blade before you start spinning the work piece.
That looks like a piece of PT decking. Looks like its an inch thick. Check your blade tooth count. You should try and have about 3 blade teeth in contact with the work piece.
