If you have to drill or machine small rubber parts, it's one way to do it. Ever try to drill a hole in a rubber stopper?

The only thing is, you have to work fast!

NeoTech:
yeah i made a spade bit when i drilled in rubber.. works better then drills. I doesnt even need to be hardened.. =)

That depends... :lol: Where you live and where you buy blades.

 I live close to this one and  they sharpen some of the wood working blades I use. They have band saw stock and do pretty much the sizes you want, but it's nice to use stock size: you need one and just pop in before 17:00 and take a box from the self.

See table in the middle of the page "Varastomitat:" sorry it's all Finnish, but I put it there just to illustrate standard sizes:

Not all sizes have all tooth configurations on stock. I have 10/14 tpi and it works to about 5-6 mm thick material in my use. I have one very fine, looks like a hack saw blade, but I use it very seldom.

Ah well, Sweden is the land of the retards when it comes to get hands on industrial products..  I need to call around then.

PekkaNF:
It's pretty much the same here, but there are ways around that problem, usually you just need to ask for a"quote" and then you need exact amount of cash when you collect the stuff. But this shop is great.

Sorry, I put incomplete link on my previous post. Should have been this:
http://www.malmintera.fi/vannesahanterat_bimet.htm

I have the bog standard 4*6" band saw and it uses this blade (lenght*width*thickness):
1638 x 13 x 0,65 mm
Available tooth/inc is:   6/10, 8/12, 10/14

My saw has about 200 mm OD wheels and close to 200 mm wide cut. Throat clears close to 150 mm dia. I believe they come up with biggest  useful frame size and smallest wheels for this blade, I.E. I believe that it does not pay off to use smaller than 200 mm wheels on 0,65 mm thick blade. Two sizes up and then you are in 20 x 0,9 mm blade class. This needs bigger wheels tought.

If you know the throat you want, you'll get the location of the third wheel and there blade lenght and then choose next popular size and design on that one.

There are very many suppliers, but not all have all sizes.

This shop has lenox and list some popular sizes:
http://www.chestermachinetools.com/lenox-bandsaw-blades-5335-p.asp

Check Die Master 11 M42 Bi-Metal    13 - 0.65mm    1638mm    18    H110, HV128    BAN-B-021
at £19.24 it's pretty good and 18 tpi might be the fine tooth you are looking for. Is this size anything you are looking for?

If you go longer blades, standard is bigger blade = bigger turning radius and bigger wheels. How big throat you need?
