Just picked up this neat old 12" bandsaw at a flea market. Didn't know what it was but it looked good, the price was right and my wife didn't argue, so I paid the man, stuffed it in her car, and hauled it home. Posted a pic on OWWM.org and had an answer in three minutes... it's a 1930s vintage Blue Star. Primarily a wood cutting bandsaw, although it works as is my thought is to change out the 1929 vintage GE motor for a treadmill motor with a variable diameter pulley for speed control and use it for light metal cutting, since I already have a small bandsaw for wood. It needs a bit of attention but nothing serious. Now to put the 10" Shopmaster bandsaw on CL to free up some space...

Very solid looking piece. Great score. Mike
 
here is my craftsman 3 wheel, i changed it over to a treadmill motor,works good on steel and wood, just change the blade. I silver solder my own blade for metal cutting out of doall bulk material, I had a 14" 2 wheel before this that i did the same thing to, bit took up too much floor space.

Yeah, a lot more solid than the Shopmaster.

Any advice on blades? It came with two blades, an 18 pitch and a 10 pitch, though the 18 seems rather dull. I want to use it primarily for aluminum, 1/16 to 1/2" thick. Is it unreasonable to want a single type compromise blade? Looking at Lennox Diemaster blades, which I can get in 10/14 or 14/18 variable pitch from bandsawbladesdirect.com.

make your own blades, have been for years, silver solder them together, google it. Do all bulk blade material
 
Looks like a nice score! I am currently doing a speed reduction on a vintage bandsaw, Brino kindly posted the link above. I went a different route but the treadmill motor approach sounds good.
 
18 tpi blade will be a bit coarse for 1/16" aluminum, I would usually run around 24 to 32 teeth for stock that thin. On the other end of the spectrum, 6 tooth skip was my go-to for 3/8" and above, again in aluminum. A 10 or 12 tpi is also quit acceptable for the thicker range and cuts a bit smoother. So the short answer can you make one blade do the range? Yes, but not effectively nor efficiently.

Others may have different preferences, these are just what I found to work well for what I was doing. Nice saw, by the way! :encourage:

Hmmm, I can get a 24 pitch in carbon steel with a raker set... in bimetal I can get 14/18 or 10/14 variable. Probably I should get a 1/4" wide 24 for anything under 1/8" and a 3/8 or 1/2" wide in one of the coarser pitches.

Gonna have considerably more tied up in blades and tires than the $50 I paid for the saw (yeah, nice score) but that's the way it goes...
 
I have 4 for my horizontal: 24, 18, 14, and a 10 on the way
Mark
ps and I might also get a 32
