Hi,
I bought this bands aw some time ago and now ant to get it operational. It's approximately a 20 inch unit. There was no motor when I got it so don't have a clue except for a bolt hole on the side. If anyone recognises it and has pictures of one with motor attached I would appreciate a peek.
Cheers,

Appears to be a bracket- missing for the motor. Drawup a bracket and get it welded. If your not visual, make a wood template to work out the placements of the base for the motor You have the opportunity to add a 1 or 1\2 how motor. Just make sure it turns the right way. New tires, perhaps bearings, roller guides and a little paint, you'll have a great band saw. Tom kQuote:

I think that saw needs a base made up, and the motor will sit in that part.
Hooroo.
That looks very low to the ground.
I wonder if the motor would be in a box-type base which the saw sits on.

I think you are right and probably the way I have to go. Just want to try and make it mobile.Quote:

Looks like a very nice bandsaw :)
Mounting the motor underneath is probably neater and more practical but it can also be mounted to the side like my Paulco was by its original owner. When I refurbished it I decided to keep the side mount design.

I agree with the posts above about the motor being quite separate to the saw. Given the size, I suggest no less than 1.5Hp, better more, maybe even 3Hp. You would be looking for a 1425/1450rpm (4-pole) motor. Possibly using a larger driven pulley than the one in your picture. That looks way too small to transmit even 1.5Hp with a single belt.
Looks like a well made professional bandsaw!
I have one exactly like it! Best I can tell is it is either a war finish Crescent or a Wartime copy thereof. Mine has no nameplate on it. Mine has a motor plate at the rear, although I suspect the others are correct re. the motor mounted separately on a base and mine has had an add on.

Is it because of the existing pulley?
I've heard a company selling bandsaws claimed less draw or more torque with a four pole when questioned why they'd chosen that Vs competitors
Or is there some other reason that makes a four pole more motor, perhaps a looser belt considering the distance?
Or could it be the rpm to suit what's possibly poured Babbitt bearings?

Very nice unit, Nick!
I'd consider your motor bracket to be swung off the wheel base.
I have a big (32" ?) 'Premo' (also by Makers Unknown), that needs re-motoring. I swing between fussing over pulley sizes to get the internet's favourite blade f.p.m, and splashing out on a V.F.D. / V.S.D. combination...
Looking forward to see your progress.

Looks like you have a very substantial band saw there. It's certainly well worth the time & effort to get fully operational again. That saw may have originally been driven by overhead shafting.
Have a look at Wolfenden and Wadkin band saws of similar capacity for guidance on motor 1ph or 3ph, size, power and mounting set up.
A word of caution - being a very solid cast iron framed band saw it will be very heavy, and will have a high center of mass - which means that IF you make it "mobile" it will have a very high probability of toppling over.
The only way you can over come that will be to make a very substantial base frame with a large workshop foot print - which then sort of defeats the "mobility" option. Once that unit starts to topple, only the Hulk would have any chance of saving it, or lots of damage!
I have a Woodfast BS500 which is a fabricated frame design on a manufacturer supplied "mobility base" and even it is twitchy on a good floor surface.

If the wheels are 20", (using photos) then the pulley is 4 - 4.5" in diameter.
A (4 pole) 1440 rpm motor with a 2" pulley will then turn the 4" pulley at 720 rpm.
720 rpm x the circumference of the 20" wheels works out to about 3500 fpm which is about right for medium size bandsaws, and I would not go much higher than this for this saw
So - if you went for a 2880 rpm (2 pole) motor you would need a 4" pulley on that one to maintain the same band speed.
