The original title of this topic was “Venting about my Bandsaw… I NEED HELP!” but I decided to change the title because there is so much good information here that it should be a reference for anybody with bandsaw problems. If you read the thread, you will find a goldmine of tips for fixing and tuning a bandsaw and how I got mine working again.
Here is my original post:
VENTING ABOUT MY BANDSAW… I NEED HELP!
sorry, but I AM TICKED OFF AT MY BANDSAW!!! ...ok, just had to get that out.
The sad old fella: (we have a love/hate relationship right now)
I have tried everything. I have read every book on “tuning” a bandsaw. I don’t need to be told to make sure the wheels are in the same plane, use a dollar bill between the blade and blocks, etc. I have done all of that. AAAAGGGGGG!!! ...ok, still venting.
The Bandsaw: Delta 14” with riser block. Actually has “Delta, Milwaukee, Rockwell” on the tag, which gives you an idea of how old it is.
I am just trying to “resaw” my lumber, like I have always done. It has never been perfect, I have always suspected that the saw was not perfectly true. I am pretty sure my problem is a wheel that is not true. But they are soooooooo expensive. Almost not worth the repair.
The problem(s): It rocks when it turns on. I don’t mean vibration, I mean ROCKING. I have gotten used to that. But the main problem is that it won’t cut straight. I am getting an ”S” curve cut through the wood. The blade enters and exits the wood in a different place.
It’s just soft 1×6 Philippine Mahogany. I’m not asking that much of it. I don’t force it… I go really slow.
I started using my resaw fence… then my “single point” attachment (both home made but very effective and even adjustable). But you can’t account for “Blade Drift” if the blade is DRIFTING IN TWO DIRECTIONS AT THE SAME TIME!!! ...still venting… That’s right, it’s actually twisting in within the board.
It drifts left in the upper part of the cut and right in the lower part. WHAT!? Is that even physically possible?! What universe is this bandsaw from?!!
The further I cut into the wood the worse the “S” curve gets exaggerated. End result: eventually blade just burns the wood, won’t cut, and pisses me off. (sorry)
I was having problems several months ago and I actually spent $150 on the Carter bearing guides thinking that might help. It sort-of did for a while but it seems to have gotten worse lately.
By the way, the blade is 3/4”. I have tried tracking it in different places on the wheel, further forward or back. The only other thing that I am wondering about is the possibility of blade tension being wrong?? I donno. I have tried all different tensions also. ‘They’ recommend setting the spring a little higher than the scale size (past the suggested 3/4” mark).
The blade itself is actually a pretty good quality blade. It is made for resawing.
I wonder if my saw is just twisted like a hunchback? Maybe it’s just got a little bit of scoliosis like me. It seems like such a good saw but I just can’t get it do cut.
I’m mad and sad because I really like this old bandsaw (and can’t afford another anyway). Please help me, LumberJocks! (Any advice or new bandsaws you can give me are appreciated.)
