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.htmI 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.aspCheck 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?
