Hey Guys;
I have a 24" Delta Rockwell bandsaw that I got at a school sale for $400. Too dangerous for today's kids I suppose but good for me. It had a lot of lookers but everyone seemed to be shying away. I looked and figured it was because it was 5 HP, 3 Phase. Being an electrician that was no problem for me. The real problem was what I did not see. The bottom drive wheel was missing. I looked at the top but not the bottom. A friend of mine who has a large gap bed lathe and always likes to do something out of the ordinary volunteered to make a wheel. Delta wanted $910.00 for a new one. In a couple weeks I had a better than new machined and balanced, not cast, drive wheel.
We went to a local bearing store that sells belts and got a piece of ruff grip conveyor belting. After applying a heavy dose of barge cement to both wheel and belting, we let it dry/cure for about 3 hours. When we rolled that wheel to belt they became one. You won't get that belting back off. To be sure I put two pop rivets in both ends of the belt. Barge cement is what shoe repair people glue rubber or leather soles to shoes with. Tough stuff.
Slow speed for metal cutting was obtained by installing a VFD. Having employees, I tried to keep things simple. Three selector switches, 1) METAL WOOD
2)SLOW FAST, 3)OFF RUN. The drive then picks one of the four programmed speeds and I don't yell at people trying to cut bar stock at full speed!
When we first turned it on we could barely keep a blade on it. If it could be adjusted, those school kids adjusted it. Replaced a couple stripped bolts, 1/2 of the blade guard, and two ball bearings. Last was to fabricate some missing adjustment screws for the blade guides. Except for stickers and graffiti the paint is not in bad shape. The rip fence, if it ever had one is missing and being fabricated now.
Love restoring guns and old machines. Someday someone is going to own a bunch of both!
