In case you haven’t figured it out yet, the 4 x 6 Horizontal/Vertical Bandsaw is a partially finished kit. Yes, it lops off bits of metal, but do you like the off-square cuts? If the saw’s accuracy meets your needs, don’t waste your time reading this article. But if you would like your cuts to be closer to square, I might be able to help you.
If you are interested, please see
Your comments are welcome. All of us are smarter than any one of us.
Thanks,

Thanks, Rick. Your email informed me that this group exists, and I bought a Taiwanese version, vintage 1983 or so, from Craigslist a while back. It needs a bit of restoration, which I'm not ready to start quite yet, and I figure while I'm waiting I should read everything I can lay eyes on about improving them. I saw mine run for a moment, until it tripped the inverter the guy was running it on, but it doesn't seem to want to run now. He'd been storing it outside in the rain, I've had it in the shop drying out for several weeks now, but the motor doesn't even hum. I did find a megger on ebay a while back so one of these days it's going to get tested. Trying to get cleaned up and organized, so I have a place to work, and can get to the stuff I need to work on. Seeing progress in that, which is good as I've acquired several other projects recently. Thanks!

Bill, ? The 4x6 is a great saw and well worth the time to tune-up. Good luck with that motor! If I had to replace my motor, I’d be tempted to put in a DC motor with controller from an old treadmill. ? Rick ?

Tom,
My guess is to get as big a motor as you can find. Hopefully others have a better answer.?

What motor would I look for to mount on my bandsaw?
Thx. Tom

I second the "as big as? you can find" suggestion.
I got one on ebay with the controller years ago for my mini-mill.? It's still just a mini-mill, but its a much better machine than how it started out.? I made a pair of 3 speed pulleys for it, but I never need to change it from the middle speed.? It has enough power to go whatever speed I want from the middle speed.? That's the big advantage of an overized DC motor.? You can achieve all the variable speed you need the dial instead of the belt.

I have a couple of wheelchair motors I just found when clearing up my workshop. Forgot I had them and not sure why I have them. Would they be suitable on a bandsaw, do you think?

Hi All
Thoroughly recommend you look at Ricks article?for setting up the saw for squareness (and copy for your files).?
I had a hand in reviewing it for Rick and its sound.? Follow what he's says and the the saw will cut square.??
Some bits are just brilliant, like the set-screw in the back of guide assembly bracket on pg21 - so simple and easy. I'm guessing that not 1 in 100 saws will have this stop, which makes setting the back guide roller-to-blade distance independent of the blade twist setting, which is a major part of setup for squareness. I'm doing it to my machine now to replace the clunky stop I had.??
This is one of those posts like John Pitkin's 'Blade adjustment and tracking' doc - jv.

I would vote No.? Although they could probably be made to work, they are probably made to operate off of a battery in the 9 to 24 Volt range.? So you would have the additional expense of reducing the line voltage to the battery voltage and the additional expense and I-Squared-R losses inherent in operating at a significantly lower voltage and higher current.? ? ?

Robert,
The controller that comes with it supplies the power. You just need 120 VAC.?

Hey Rick, I'm not sure, but I think you might have missed the reference to "wheelchair motors".? ?
