25 dollar craigslist bandsaw.

[KraftwerkMk1Jetta]

I bought this Taiwan made bandsaw for 25 bucks this morning, it works, but I'd like to slow it down for metal. Is it as simple as swapping out the pulleys? Does it matter which pulley of the two? Here's a couple pics

No, yes.

Just an idea could you put a step pulley on the motor to make speed change a little easier. That and the blade.

 

[KraftwerkMk1Jetta]

No, yes.

Thanks for the insight.

You will likely need a jackshaft to be able to get the drive ratios to a point where the bandsaw wheels will turn slow enough. A blade speed of 125-200 linear feet per minute at the teeth will work fine for most things. If you do not know about the pulleys, you will need to do some reading about gearing ratios to get a good grasp on it. Something like below. Motor turns jackshaft to produce lower output speed. Jackshaft turns saw to produce even lower speed.

Thanks for the insight.

You're welcome. You asked, I answered. This gets discussed on a weekly basis. It just gets old.

Then ignore the post and keep your mouth shut.

Got ya, thanks for the help!

Look back at edit of post number 5.

Old furnace blower fans are a good source of larger diameter pulleys. Bearings for jackshaft would be called pillow block bearings. All parts available on Amazon.

Cool, I might play around with it this winter and see what I come up with.

Right on !

It will be difficult (probably impossible) to just change the 2 pulleys and com up that that slow of a speed. That is why you need a jackshaft and a second belt and set of pulleys.

Once you have an idea of pulley diameters, shop eBay or look for surplus places online.

One last question, would getting a motor from a horizontal metal cutting bandsaw and swapping it into this one work?

 

[zkling]

Not unless you find one that has an integrated gear box.

Last question, no. If you don't want to try the jack shaft method, you could get a gear reduction box like in the link below. You will need to get on a google calculator to find out what speed you are currently turning to determine what gear reduction you would need(ie 40:1, 50:1 etc).

Kraftwerk how many amps is the motor on that bandsaw.

Thanks fellas!

If you have a free riding lawn mower transmission or trans axle that could be adapted here.
