Bandsaw grief

I have a vintage 1995 Delta clone.....
I recently replaced the bearings, and guide blocks with Cool Blocks....
Put a new Bosch 1/8th blade on it, but can't get it to track right....
I fooled with shimming the wheels, and got it to track ok with low tension, but it goes out with higher tension......
Could it be the blade ??

Have you check the condition of the tires?

I have never had any luck with an 1/8 blade. My scroll saw works better anyway. Try a 1/4 or larger blade.

It's unlikely to be the blade, unless the blade was thrown off the saw while it was running and got tweaked somehow
.
Did this saw track reliably with a 1/8" blade in the past, before you performed the bearing change, or have you just started trying to use a blade that small on this saw?

Does the blade "dance" back and forth when the saw is running, but still stay on the wheels, or does it just come off the wheels completely?

I've only used 1/8" blades since I've had the saw..... It doesn't throw the blade... When it's tracked in the middle of the top wheel, it tracks to the outside on the bottom.... The saw runs ok with this condition (no "dancing") but it makes me nervous ..... I ordered a Timber Wolf 1/4" blade today from Amazon....
We'll see if that makes a difference.....

Sounds like one of the wheels needs a spacer added to bring it in line with the other.

I think Gary pedded it, sounds like the wheels aren't co-planar. Not the end of the world if they aren't, the saw will still cut fine, but still isn't a bad idea to shim them into coplanarity

wheels should not be co-planer

According to this widely mentioned You Tube by the expert Alex Snodgrass, at 6:00 into the video he states the wheels should not be shimmed or "messed with" and to leave them alone at the factory setting:

The answer to your question will only be as detailed and specific as the question is detailed and specific. Good questions also include a sketch or a photo that illustrates your issue. (:< D)

that's what you want the blade to ride in the middle of the top wheel and it will ride on the out side of the bottom wheel, but the teeth should be on the bottom wheel , make sure the blade track's ok when you saw a board and you don't have to hold it real hard next to the fence, take a board like a junk one like 2 inch thick and mark a line in the center and move the fence away , now cut about 1/2 way down the board , now use the T bevel and put it on the fence and lock it down like on the edge of the bed and the other end on the wood this gives you the way the blade is cutting, now remove the board and move the fence over , now put the T bevel on the fence and loosen the fence so that the T bevel is square to the fence, tighten up the fence, now the blade will track good when cutting , here is a good video to watch also, also you don't want the top and bottom wheel co-planer eather what this video https://www.youtube.com/watch?v=wGbZ...eature=mh_lolz

Very good video.... Thanx for posting it....
When my new blade comes tomorrow, I'm going to remove all the shims, and start over....

Good advice, in the case the machine hasn't been messed with previously. In this case the bearings have been changed and there is a chance of misplacing factory spacers or having bearings not to factory specs causing the misalignment. If.the problem contiues, as a last resort check the spacers if any.

Twolf blades routinely have misaligned welds. if you want a blade for checking a saw's issues, get a lennox from iturra design. lou really knows how to weld a BS blade. here's my now departed 18" jet with a new 1/2" twolf:

https://www.youtube.com/watch?v=LrxBP8YBKYM

note the oscillating movement of the blade, due to a defective weld. same saw, with non coplanar wheels thanks to a lousy authorized jet repair dealer, but with a 1/2" lennox from Iturra:

nuff said?

there's a solution to every problem.....you just have to be willing to find it.

I get Timberwolf blades from Grizzly

I buy 6 at a time to minimize shipping. I have no issue with misaligned welds. If I did Grizzly would take it back in a heartbeat..... Good Customer Service.


The Timberwolf site:
http://timberwolfblades.com/


I weld my own blades also. I know it's not easy to get straight welds, but I do it routinely with 1/2" and 3/8" blades. I can weld 3/4" blades but those are the ones I get from Grizzly, it's just easier and I don't have roll stock in 3/4" wide.

I'm sure Iturra makes a fine blade also. I use Lennox roll stock and Starrett for my 1/2", 3/8" and 1/4" blades. They last a very long time. I also have 2 metal cutting bandsaws and weld those as well. There is nothing worse than a broken blade smack in the middle of a project. The welder has paid for itself many times over.

I should have worded my original post better.... I only changed the thrust bearings, guide blocks, and the blade..... The wheel bearings are fine....

Timberwolf blade came this morning..... I set up the saw per Alexs' video, and I was able to track the new blade ok.... Still not sure if it was the Bosch blade, or me paying more attention to the setup.... The new blade is much sharper than the Bosch, and cuts better than any I've used in the past....
Thanx, everyone for your thoughts.....
