View Full Version : Need manual or info - Jet JBS-14MW band saw

Bought this older Jet band saw last week.
It has 6 speeds via 2-stage pulley system.
I need to know what the factory speed settings those 6 are.
I suspect even the slowest will be too fast for anything but aluminum.
Before I spend time and money slowing it down I'd like to know the starting point. If it's in the ballpark I have a slower motor I can use.

Better yet, does anyone have a PDF of a manual for this machine?

Speed calculation is pretty simple and required if you're going to slow the old girl down. An even easier way to is cheat and use a calculator.

Well, I can't cheat with that calculator because mine has an intermediate pulley. But someone did send me a manual.
turns out it's just 3 speed, and the slowest is 700 FPM. Even replacing the 1725 RPM motor with an 1100 RPM version won't get me but to about 400. I need about half that I think.
I do have a 60 RPM gearmotor with a big pulley on it. I'm going to eyeball that next time at the shop.

Why not ask Jet about it? You can try this site for manuals: http://bandsawmanuals.com.

I think the manual I was sent covers any questions I have that jet would be able to answer.
interesting link, but it did not cover my older model.

I did repair and reinforce the blade guide casting. I'm looking at ways to add side roller bearings to the guides instead of the hard plastic blocks.

At this point I'm trying to decide whether to spend time on it or sell it and buy something closer to what I need.

Remember to always consider your need. Give a little more patience, maybe later, someone will pop out and say he’s got the manual you need.

Got the manual now. If anyone else runs into this, email me for a copy.

thanks for the input.

That’s good! Where did you get a copy of the manual?

Actually found it on a wood router forum. Only place I found it, and had to register to get it.
Felt bad about that as I probably will never go back.

I guess they have a manuals’ section in that forum. I hope mods add one here too!

Calculate the speed of the intermediate shaft and repeat using the resultant RPM as input to the next calculation for the rpm of the final output shaft. If the result is still too fast (SFM blade speed), swap the motor for a larger three phase unit and use a VFD.
