Josh, I used to work in a machine shop where I had to remove gears off of 
shafts. We used an acetylene torch to heat the gear fast, so the shaft didn't 
expand as fast. Using a slow heat source will heat the coupling and shaft at 
about the same rate. You want to expand the coupling faster than the shaft 
expands. Doug Mountjoysv Rebecca Leah C&C Landfall 39Port Orchard yacht club
