Here's a small info here about your band saw http://vintagemachinery.org/photoindex/detail.aspx?id=18347
That's definitely a sweet deal. I think it's a rare find.I get my blades on sawblade.com.I advise you to get their bi metal blade, cuts like lennox blade but not expensive.
That's a good deal. There's a google group for 4x6 band saw. If you'd like to know more mods and set up of your saw, it's also a good place to post/ visit. Get yourself a good quality band saw blade, I use bi metal Haltbar band saw blade.
My weekend was a little productive, I have to help my friend to move a 500lbs band saw machine. My friend rented a forklift and it was just smooth job.
By the way, how's your band saw performing?
