I have an old (1946) 14” Delta bandsaw that I just made a couple of improvements to. I replaced the tensioning spring with a “Cobra Coil”, and replaced the tensioning knob/shaft with a Big Horn crank. In doing these, I found that the upper hinge piece is becoming deformed (apparently a common problem), causing the upper wheel shaft to be quite loose. The blade still tensions up OK & tracks as it should, but this hinge piece will get worse before it gets better, so I want to replace it.

I see that Mike’s Tools lists one for about $9.00 + shipping, and an Ebay seller has one for $27. And I’ve also heard about an improved version from Iturra.

Does anyone have any firsthand experience with any of these? I guess my question is should I spend the extra $$ on the one from Iturra, or is something equal to the original OK? I’m thinking maybe the improved metal used today might be stronger/better than what was used in 1946, making the original design OK. (Or maybe today’s metals are worse…)

Thanks!

I’ve ordered from wmprice before, but I know the guys from Accura/ToolSupermarket. Both of them sell import replacement parts. I don’t know anything about Iturra, nor does he advertise online.

Replacing that spring and adding a ‘crank’ is most likely what caused your problem. Those brackets can easily be bent from over-tensioning and exceeding the machines design. It should not cause the upper wheel to become loose though – so that may be an indication of another problem somewhere.

Oh, I have that same crank on mine and I like it. I agree, don’t over-tension with the heavier spring.

The hinge was already deformed when I disassembled the parts to install the crank & spring, and the axle is loose due to the deformed hole in the hinge. I think all will be well after I replace the hinge.

The upper wheel axle is loose by design and does not fit sung into the hole in the bracket… when you remove the nut holding the upper wheel on, it will flop around like a fish out of water – which many people incorrectly interpret as being broken or damaged. Tightening the wheel nut will pull the shaft against the pivot pin and secure it, removing the slop.

Interesting; I didn’t realize that. It does tighten up & square up OK. Maybe it doesn’t need replacing after all. The saw works fine, maybe I’ll let it ride for a while.

Thanks!

You have me wondering what mine looks like. I have an old one too.

I can not get the upper wheels bolt off. I broke my tension bracket and need to replace it but I can’t get my upper wheel off? Any suggestions? I’m just trying to learn how to use these machines so any help would be greatly appreciated.

Nancy- What make/model is your saw? On my old Delta, the subject of my original post in this thread, there’s just a nut that holds the upper wheel on its axle. Remove the nut & the wheel just slides off. Are you saying that you can’t loosen the nut, or that the wheel won’t come off after you’ve removed the nut?

As an aside, you may want to start your own new thread with your question. It’ll likely get more attention that way.
