I really liked the tool they used to heat up the studs prior to removal. Have neve seen the process they used for pouring the bearings. Was not like the way I was shown in MN by one of the members of the Lady Slippers Club using the old original tools. What I did not see was them weighing the rods, and pistons to get them less that 1/2 gram difference. Did notice that they used a counter balanced crank.
