11 inch Band saw

[SteiniesStuff]

Hi all,
I bought an 11 inch Magna Band Saw at a yard sale, I think it is a 1959
model. It uses an exterior motor, which I don't have. What size motor do
you think I need?
Any help sure would be appreciated

The bigger the better. That seems like an odd size. The speed is more important when replacing the motor. It also depends on the blade you use. I have a 2 1/2 hp motor on my larger bandsaw but with a 1 1/4" deep blade with 3 teeth per inch even more power would be nice. But then I also use a 9" bandsaw and I think it has a 1/2hp motor and within reason it works fine.
Check around for a simmilar size saw and see what they use, most adds will tell you the HP or amps used.

Hacksaw you may want to Google it and find out exactly what size it takes , for I know you want it to run right . Or maybe someone on this site knows exactly what size of motor it will take . I wish I knew more to help you , Good Luck on your findings !!! Marshall

Hacksaw, your magna bandsaw could have been an accessory tool that came with an old model Shopsmith. The shopsmith was sold with I believe 5 different tools that worked off of the main motor by a coupler. That could explain why it did not come with a motor. A lot of Shopsmith owners would mount the bandsaw, belt sander amd jointer on a stand, put a pulley of the stud that was meant to accept the coupler and mount a motor underneath the stand with a belt linking the tool and motor.......Mike

Thankyou Mike, you were right, This is a Shopsmith Magna 11 inch
bandsaw, Now I need to find me a motor for it, I believe it takes a
3/4 horse.
Thanks again

A 1/2 hp or 3/4 Hp will do a small band saw like that just fine I doubt it will handle any more power. I have 5 band saws and I have a 30 year old Rockwell/Delta and it only has a half hp motor and it has cut everthing I have put to it. I have been rebuilding machines for 45 year. As for all of you that do not know there are 3 ways to rate horspower look it up.
On 120 V the max HP it will run is a 2 HP motor. No more. Any more hp rating for 120 v is false. You can not get any more amps to run more than a 2 hp. It will not compute. You need a 1750 rpm motor. The pully size will make the difference. Seed should be around 3200 rpm. I am not going to post all the charts for speeds. You can look it up on the internet. You can find all the charts you will ever need for voltage, speed and feed, and more. Do your home work.

I always wondered how companies get away with claiming "3 1/2 HP 15A" motors. For those who don't want to spend all kinds of time looking this stuff up - in a nutshell, 1HP = 746watts or about 6.5amps. In reality, without boring everyone with all the details, it takes around 10 amps to deliver that at the tool. I don't really agree though that the max you can get with a 115V service is 2HP. With a 25amp breaker and the correct wiring you should be able to get right around 2 1/2 HP (though who or why anyone would want to is a whole other question).
