For a few days I will probably take a bandsaw. I havent see it yet but it has 12-14" wheels and 6" opened mouth for wood inserts. It is strong construction but do not have electromotor. Is 1,5-2 kW motor strong enough for this bandsaw?
-
My 14" saw has a 1 horepower motor on it. It doesnt slow down for anything!

Druid
That should be fine !

1.5KW is approximately 2 hP and should be sufficient for a 14" bandsaw. You'll also want to make sure you have the motor speed (RPM) close to correct for the saw (or figure out how to step it up or down) Can you determine the manufacturer? are they still in operation? Perhaps the power and speed specs for the appropriate motor are in an online manual somewhere.
Also a suggestion: See if you can get specs on blade length in advance and find out if your machine uses stock sized blades or if you'll always be purchasing custom blades. Maybe not a deal-breaker, but something that is good to know going into the purchase.

Advice is find Timberwolf bandsaw blades for what ever saw you end up with. If you really want more horepower find a decent plimp.

If you buy one off of craigslist make sure it is not three phase if you do not have three phase...

Its hard to see on the pics but are there some kind of adjustable guides for the band above and under the workarea?
It will be hard to make precise cuts if you dont have good guides.Preferably with some kind of ballbearings supporting the back and sides of the band.

Not sure what you have there, looks like most of it is missing !
-
dbb, I have to make guides and a lot of smaller parts.
Now I found on internet that on wheels small like this blade should be thinner than on bigger wheels because compression stress. How thin I need for these wheels, 0,3mm (1/80")?
-
Druid, Looks like it should work. I have an older bandsaw that I refurbished as well. It has 10" wheels. It works with standard blades but they do break down faster because of the flexing. I would start with a regular blade and see how they do. Sometimes I'll get 20- 30 staves roughed out with a $10.00 blade and other times may only be half a dozen. ::) I have thought about getting bigger wheels but since I'm not roughing staves everyday I haven't worried about it
-
Keenan what is standard blade? Some experts said that for 12" wheels 0.02" thick blade is right.

Good question . I'll have to see what it is that I am buying ::)

Druid
Mine are .025"
They work fine on my 12" wheels
Guy
-
Well, then I hope 0.02" will be enough thin for me.
-
If I wanted advice on band saw blades, I'd ask the good folks at Suffolk Machinery. They are on the web.
-
Me again with one more question: I found 2 kW motor but I do not know what is its speed, yet. With bandsaw I describes how fast should be motor (Rounds Per Minute), any datas from yours bandsaws?
-
We don't get much of a choice in the states ,most motors for bandsaws are 1750 rpm !
The slower the better in my opinion !
We pulley to suit us !
Guy
-
Thank you Guy, thats information I was looking for. I think this one is about 900 rpm, is it too slow?
-
druid
I am sorry I don't have time today to give you a proper answer ,but if you are mechanically minded you can get about anything to work ! will you be able to pulley it up a little ?
I will try to remember to get back to you when time allows !
Guy

Druid, did that saw come with a motor at all? If it did, and you knew its rotational speed, you could go by its pulley size to determine the new pulley you'd have to use. For instance, if the old one was 1750(1800 rpm), with a 2" pulley, you'd want to go with a 1" pulley on the 900rpm motor. This gives you the same speed on the blade.
For what it's worth, I don't think you'd have any problem with a 2kw motor having enough torque to be able to under-pulley it.
Motor speed is not nearly as important as torque, as if there is enough torque, you can run multiple combinations of pulleys to achieve the blade speed you want.
