Band Saw Blades
An older Craftsman 10" band saw on a stand. Not a giant, not a high priced ubber accurate saw, but a really good deal for $10 delivered. After a little research I discover the blade length required is 72 5/8". No problem. A quick check of the local big box, nothing. Check of the local hardware stores, nothing. Check of the local Sears outlet, nothing. Check of the big Sears 45 miles away, nothing. What to do now? The local big box has a 93" blade for $10 so I thought I would try to weld my own. After several different attempts and trying different bonding agents, I finally come across a method that works pretty well for me.
Then I use the belt sander to taper the ends forming what is essentially a scarf joint. I shoot for the taper to be about as long at the blade is wide. I then put one end in the jig and wipe it with acetone.
The key to the whole operation is the right amount of heat and the proper bonding agent.
Then it's time for the fire.
