Cheapo blade guide, zero-clearance insert, and tires on a little bandsaw
I got a little 10" bandsaw for $20. I don't have a "real" bandsaw still, and this thing was so cheap, I figured why not. It has come in extremely handy for rough cutting prior to the router table or whatever, even at its small size, and it cuts much better than a jigsaw.
However, there were no inserts, the lower blade guide hardly worked, and the tires were extremely worn, so the blade kept falling off the wheels.
I ended up making a UMHW plastic lower blade guide and an oak zero-clearance insert (both out of scrap I had laying around) and re-covering the tires with grip tape.
The results make it a pretty usable little saw for what it is, and it was worth the grand total of $3 and 1-2 hours I threw at it. I'll eventually get a nice 14" ridgid or something, but in the mean time, here's one way to handle this.
