RE: Spun bearings
Scot,
I use Loctite 620 Retaining Compound for my prop hubs and bearings when I have an issue like yours. Depending on how bad the bearing surface is spun you may need to look at Loctite 603 which is for press fits in parts that have a .005 gap. This product also is oil tolerant which you may need to consider. Not a lot of oil in there but you have gaps and oil can break down the sealant.
