Wanted to ask, is there any bearing race driver kits you guys would recommend? I know it's been a couple years since this thread was originally published so didn't know if there was something new to explore. I have the el-cheapo HF kit for the smaller stuff, but don't have anything to drive a 4in ID race.

Did the ole' oven trick for these bearings, which works great, just time consuming with the heating and cool down stages.
