hi guys, i have a new 16" rim ,s/s spokes,standard 40 spoke front softail hub and was trying to install the shells into the hub- a friend said "put the shells in freezer and heat up the hub"- i put the hub in the oven at 150 celcius for 1/2 hour and then removed with my old bike gloves and then proceeded to tap the shell as evenly as possible using a large socket but only managed to sink the shell into the hub till it was level with outer surface and then decided to put the whole kit and kaboodle back into the oven and set the temp to 250 celsius,so while thats happening i figured i will ask you guys if i have messed up or maybe the heat wasnt enough on the hub in the first place,cheers in advance-nick.
