Thanks, on my way to get some. > be sure you dont want it back off before you apply as heat is about the > only way to get it off I'm aware of that, it takes around 485F to 500F to soften or loosen most of that stuff. If I ever have to take it off, it would be to replace the bearing behind it, so telegraphing heat wouldn't be that much of a concern since the bearing will likely be toast anyway. My problem would be finding the heat, thats a BIG chunk of cast iron compared to my heat generators. Cold out today, but I did rig a dpdt switch so I could try out various braking resistor schemes, and stumbled over a 5 ohm 200 watt wirewound, a surge limiter out of our old NTSC transmitter that seems about right from about half speed its about 3 or 4 seconds to a dead stop. And if I can find another 5 or 10 ohm like it, I maybe will stick a 25 volt avalanche mode zener in series with a 24 volt relay coil so it uses the series combo at high speed, then shorts the 10 ohm once the back emf gets down to 45 or 50 volts. I measured at the motor and its back emf doesn't noticeably drop when shut off at speed, so from full speed with about 89 volts, it falls off from that at about 2 volts a second until it has stopped. Excellent generator IOW. Actually, the thought just now crossed my mind to check on making a constant current load, with which to draw say 8 or 9 amps regardless of the voltage. I wonder how many hexfets that would take... I have some very large heat sinks, but this would be a surge load, meaning tightly coupled cold MASS to heat, might be doable. I'm thinking. Novel idea that, but it would sure speed up the stop times by making the decel much more linear. > http://www.loctiteproducts.com/p/t_lkr_red/directions/Loctite-Threadlock > er-Red-271.htm > > here is a vid > http://www.youtube.com/watch?v=Z9zFgB8lTNM > Thanks everybody.
