I am new to nice bandsaws. The first 25 years of my woodworking I have always had old and cheaper BS’s.
A couple of months ago I bought a Jet 14” with the high riser.

I have a couple of questions, After use, do most of you take the tension off the blade? And please tell me your experience with a BS auxilary table. I have the Rockler, and I am wondering if I should get rid of it and get a Kreg fence…..any and all advice on any BS issue is appreciated.
Thanks

On the tension issue, absolutely ! I never leave the blade under tension while the saw just sits. A lot of the 14” saws now have a quick release system on them. If not, guys like Carter sell a good add-on.

Yes, on releasing the tension. I have the Kreg fence on my bandsaw and I love it. Easy to set up easy to use.

Whether or not I release tension depends on how long it will be before I use the saw again, if it is within 7-10 days I don’t bother. The thing you avoid is flat spotting the tires, it is more of an issue with small bandsaws like the Jet (and all the other Delta clones) that have thin tires, less of an issue with larger saws that have thick rubber tires.

The Kreg fence is excellent for the money and since the Jet uses side removal insted of back toward the front prevents any issues.

Why release the tension? I have never understood the reasoning behind it. I see the quick releases as good only for blade changes. If you release the tension now you are setting yourself up for other issues, tracking problems come to mind. Mine is always left in tension. After all, bandsaw have been around a hundred years or more and they didnt have some nifty quick release on them. My opinion is set the blade and forget it.

I have no experience with good quality woodworking bandsaws, (I have the HF one) but I’ve been around metal cutting bandsaws my whole life and no place I ever worked even thought about loosening the tension on a blade unless it was being changed out. So, I’m of the camp that says leave the tension on. (at least until someone comes up with a logical reason for releasing the tension.)

Oh, and MedicKen, I absolutely LOVE your sig line! Your kids and mine can go to the same therapist and maybe get a volume discount. :-)

Thanks guys—
I have been using it a fair amount so I guess I might leave the tension on for now anyway…the flat spot thing makes sense.

I worked for a 78 year old furniture company for almost five years, and they never, never took the tension off the bandsaws. From 6” up to the big dogs, those blades stayed on there and in tension until the rakers started falling off. (Cheap private ownership) I was the head of maintenance, and only once did we ever have to change out a tire, and that was probably 20 years old. The workers were on piece work, and they ran the crap out of those machines.
When I spent my 16 months in Shanghai for the chinese division of the same company, they made the entire frame on bandsaws, not having CNC. Never took tension off ever. Come back after Chinese New Year, (12 day shutdown, start them up and cut, cut, cut. No difference. And these were cheap chinese saws I never heard the name of, mainly because it was in chinese! Might snap blades while cutting, but never took the tension off.
As far as the flat spot thing, the blade is on full tension for about 150 degrees of the wheel, so where exactly is this flat spot? There is no flat spot. Just my humble opinion after 42 years of woodworking.

@Tennessee The issue is not industrial machines, old US big iron nor European saws their thick high durometer rubber tires are not effected in my experience. Where a long tern issue can develop is on smaller hobby sized saws with thin low durometer rubber tires (less of an issue with urethane) that are designed for use on a crowned wheel. Even though the pressure is distrbuted over most of the 180* the band touches the tire it is not distributed equally and is higher the closer one gets to the top of the tire. I have seen this in examples of smaller used machines that have been sitting with tension on the band often for years, it produces a whoomp, whoomp sound that is very distinctive and in the worst cases can throw tracking out of whack, that said it is not an issue ANYONE needs to worry about unless they have a small saw with thin tires and leave it idel for long periods of time. There is a reason the best bandsaws do NOT have a quick release of any sort, it is a phenomenon of the low end.

I installed a crank handle to de-tension the bandsaw. It is so much easier than the stock Jet handle, and they only cost $6. As far as tables, I just use the stock table and an outfeed roller for long workpieces.

I sold my Kreg fence yesterday as I could never use it in way satisfactory to me. Instead I built my own table with a miter slot on the bottom (toward me) and one the the right side to use with my miter fence.
I found this solution working much much better for me especially for resawing and the price is a fraction of the Kreg fence.

I also i have the crank handle, it works very well.

can you please post a link to this?

we don’t take the tension off of the 36” Tannewitz BSs at work…

but I do on my 14” Jet at home…. mainly because I have a Timber Wolf blade on it and they say to.

If I don’t do it immediately after I’m done…. I’ll forget for sure.

I worked in a machine shop where we never released the tension, although we used it on a regular basis and changed blades frequently. I think that sounds like something you would do if your going to store it or not use it for an extended time. My opinion for what it is worth.
