I'm building a new generator and read Dan B's comments about balancing mill components. He was having problems balancing a new mill and changed the all thread to stainless steel to prevent cogging. Without a lathe or plasma torch to cut the 1/4" plates for the rotors, I used an oxygen/acetylene torch, very carefully. After grinding, mounting magnets and pouring the resin around the magnets and saying "I wonder if...", I built a balancer.
- Get a sturdy cheap plastic bowl that's about 2" at the bottom and 6" top and drill a very small hole in the center. A cone shape might work too as long as it doesn't stick above the rotor by more than an inch or so.
- Thread fishin' line through the hole and tie a bead on the bottom.
- Put the bottom of the bowl through the rotor with the magnet side down and attached it to a fishin' swivel.
- Measure the distance from the inverted rim of the bowl to the bottom of the rotor. Get this measurement as close as possible.
- I put a line level that's flat on the bottom on the top of the inverted bowl to level the rotor with 1/2" washers for weight on the rotor as a guide. Grind some on the opposite site of the rotor and rebalance with washers...
Any ideas on improvements will be appreiciated! |
