Topic tags/keywords: bandsaw guide post loose tool band saw

I just inherited an old “generic” Delta clone 14” bandsaw. It will need work to get up and running, and before I sink any time and money into it I have a question about one issue that I have noticed right away:

The guide post is loose and despite how much I crank down on it’s tightening knob, the post still wiggles around. Don’t get me wrong; it is held in place (vertically at least) so it’s not moving up and down, but I can still wiggle the post around. It would appear that the casting that the post rides up and down in is worn, or possibly was just never a good fit from day one.

I don’t have any experience with bandsaws so I don’t know if this is unacceptable or even repairable.

Any ideas?

Thanks,

Chris

Sorry for the delay, but I just noticed your post. Here are a couple of thoughts regarding the loose guide post. On my seven year-old Delta, in the frame an inch or so below the tightening knob, there’s a set screw assembly designed to take the ‘play’ out of the guide post. When set correctly, the post will still slide vertically, but otherwise has little ‘play’. If yours has such, try that. If there’s only a threaded hole there, the assembly is missing. If there’s no type of play limiting device at all, you may have to ‘invent’ one.

If you don’t have a manual for the tool, try searching for one on the Internet to download. You may not be able to find one, but if you do, it may provide the answer. Even if it doesn’t solve that problem, it will be helpful in many other ways. Good luck!

Here’s another thought. Although I’m not familiar with the exact saw you mentioned, on my Grizzly there is a slot that the knob tightens down against. Might have to enlarge the slot if it’s pinching shut before tightening down on the shaft. Hope you know what i’m explaining. HTH

Thanks for the two replies so far.

The saw I have doesn’t have the set screw below the tightening knob… that certainly might help. Of course, to go along with that is the fact that my guide post doesn’t have a groove/channel in it either. It just has a ‘flat’ along the side of the otherwise round post. I think my next step might be to get a channel machined in the existing post, or alternatively purchase a 7/8” post from another saw manufacturer and see how that fits.

Thanks,

Chris

try flattening the end of the tightening screw ,
it may have a round on it ,
making it wobble .
you can do this with a file or a grinder ,
or hit it on a disk sander ,
easy does it .

Just an update (in case anyone cares….)

I’ve found a machine shop that will cut a ‘V’ groove down the length of the shaft. Another thought was to just order a guide post from another bandsaw that already had the groove in it. However, I believe there are some variations in sizes (some bandsaws may have 7/8” guide posts, others have 22mm posts) and with my luck I’d end up with the wrong one. So anyways, I went the machine shop route.
