What length blade?

My father in law gave me an old 14" bandsaw. It runs well but needed tires so I bought some, now I've realized the top wheel rubs the guard and the blade isn't even tight yet. What length blade am I supposed to get? He said this one is 93.5. It's a Frejoth model wa-14 serial 8852

Post a picture. For length, 93.5" for a 14" sounds about right.

I bought a new 93.5" blade thinking the old one was stretched, but it's maxed out on adjustment and still not tight enough. As you can see it rubs on top, I got it with the top bent up like that. I did use it and it does work though. But I can tell the blade needs to be tighter since it's not a smooth cut.

try this

You say it's "maxed out" on the tension. Make a mark on the fixed part of the sliding assembly to show where you are now. Then lower the wheel and slip the blade off and see if you can push it up any further than the mark shows. If so, that means your at the end on the screw/spring travel. You need to add additional height to the spring by adding a spacer on the threaded rod. It's kinda backyard mechanics but it's worth a try. Your other choice is to get blades 1" smaller in dia. and those would probably be a non-standard size.

Another approach would be to add a spacer between the lower assembly on the neck and the upper assembly. Probably about 1/2" which would take up 1" of the blade length. The spacer could be made of hardwood and just use longer bolts. More backyard mechanics, but we're tryin' to save your arse here and not spend a lot of $$$. bill

Grizzly has some 93" blades: http://www.grizzly.com/products/cate...spx?key=165994

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)

If you think the 93.5 is too long, why not try something shorter? How about taking the current blade off, loosening that tensioner as far as it will go and putting some string around both wheels to get an idea of the shortest blade you can shove on there.

You can get blades custom made to length, but there are some standard sizes just below 93.5 also - 92, 92.5 etc. They're just a smidgen harder to find than the others. Hartville sells 92.5, that's an inch less than you've got now. If the string shows that would be too tight to start, then you can try ordering a custom 93.

Insert witty signature line here.

The adjustment screw is maxed out and it doesn't have a spring. I thought of adding a block to push the adjuster up more but as you can see in the picture the top wheel is already riding on the guard which is also adjusted as high up as I can get it without drilling new holes for the mount. I'm at work now so I'm not sure if I can move the whole upper assy up with spacers, but thats a good idea, I'll look when I get home. I didn't think of measuring the length with string either.

Thanks guys, with that advice I'm sure I can figure it out now. From the little I can find I guess frejoth is an overseas brand that hasn't made bandsaws in years, can't even find an old manual or good info. Thanks again!

Good idea! Just use a string that won't stretch or a length of wire.

Dumb question here: Are you sure that the blade is actually 93.5"? As Mike said, 93.5" is the "usual" size for 14" band saws.

Use the right tool for the job.

Those who say it cannot be done shouldn't interrupt the people doing it.

If the tensioning spring is missing then that could be where your troubles are.

no spring?

Now that's more like it. Go to page 30, part no 43 coil spring, here to see what parts are needed from the exploded parts diagram:
http://manuals.harborfreight.com/man...7999/67595.pdf

Sounds like the upper wheel is at it's limit of travel since it's rubbing on the cover. That 93.5" blade may be an inch too long. THat's why I suggested, if you want to keep that size blade, going with a 1/2" riser spacer on the throat. Another less "pretty" way and I've only heard of this being done, is to wrap the tires with some friction tape which will slightly increase their diameter. That's real "backyard" but it may work, I donno?

You can order a spring from HF if your's s missing. bill

Dang, I do have a spring, I just never noticed it. I can however add a spacer. But I just did the string idea and it measured 92.5" at it's smallest setting. Ill order that size blade and should be good. Thanks for all of your help. Adjusting the throat on this seems like too much work to save my $11 blade lol

Thank you for that manual though! It looks very much like mine.
