Topic tags/keywords: jet jet 710750 18” 18-inch bandsaw

Hi – I picked up a Jet 710750 18” bandsaw used the other day. It had a rusty table, which cleaned up nicely with 220-grit, a carborandum stone (coarse then lots on the fine), then 0000 steel wool, with WD-40 to loosen it all up. It has very few hours on it.

But it has a small problem. One side of the lower rear bearing guide has a bit of rust on its riding surface… enough that you can feel it with your fingertip if you reach inside to it. It looks like it had a drip through the guide plate. As you probably know, getting that table off is going to be a job, and required an assistant of the male persuasion (muscles). I know I SHOULD replace it… can I get away without replacing it? Or should I have my palms smacked for even thinking such a thought?

I have the manual, so it isn’t like I’ll be going in totally blind. My only excuse is probably that I am reluctant to take on yet again something TOTALLY FOREIGN to me. Scary, you know! And it is another project among the many that go into restoring an old house to its former glory.

Thanks in advance. {ducking}

Evening M. Not sure if I’ll be any help…But If you have the manual you won’t be going in blind as you said. That’s a beaut band saw and the table looks big but not massive.
A little WD40 on the bolts on the trunnions and wait a bit and they should come loose.
Try a google on the part number for the table and see if you can find out how heavy it really is. Might surprise you. Never give up. :)

Thank you Mark. Encouragement is good! The bolts and all are actually not dirty or rusty at all. This bandsaw had about 30 minutes of use on it. All these items sat in their shop, almost never used. Oh, and it’s rear fence rail/guide is slightly bent. I’ll have to apply some judicious pressure. :-)

They bought it in 2005, and gave it to me for 1/2 of that price. They sold me 5 items, and the aggregated cost was 31% of today’s Amazon price. Only the planer had any hours at all. That bandsaw, other than that rusty guide and the “cold one” partial ring on the table, is CLEAN. Original 3/4” blade with no wear at all. All because a poster on LJ or Creek recommended placing a wanted add on CL. Funny thing was I got everything but the TS and DC I was looking for! But these were items I was fretting over about not having. And never having enough $ for. So again, many thanks to that poster, whoever he was!

If the bearing turns freely I would put a little oil on the surface try to clean the rust off as well as possible without getting anal and try it. If the blade runs smooth underload you’re good to go. If you can feel the blade hit the rough spot then change the bearing.

It turns out I called JET support today about aligning the wheels, and making them co-planar. I asked about that guide as well, and he said pretty much exactly the same thing. He also enlightened me about the whole alignment and co-planar thing as well. Interesting world we live in!

Have your say...
