I have a watchdog 2000 enduro computer. I am borrowing it from a freind, the last time he used it he lost the magnet off the rotor. The instuctions say to drill halfway into the rotor with a 3/16 drill, and epoxy the mag on. My question is is this how you guys are doing it? He did not drill into the rotor and I dont want to but if this is the only way to keep it from falling off then so be it. I guess any info on magnet mouting tips would be greatly appreciated. I can get the rare earth magnets from work and I can easily grind them to size if need be. I emailed the company but havent got a reply so I figured I'd see what you guys have to say, Roselawn is 5 days and I hope to get this thing figured out by then. Then the only problem will be trying to recalibrate the tire size with snow chains on It :laugh: Thanks Jeff
