I can second Roy's retaining compound recommendation. I bought that after some tips for some bench sander rollers I made, and had to use it for something else recently which I foolishly thought I needed to disassemble afterward (forget doing that). Mine is actually the 680. Those Loctite products are weird. They actually dry from a lack of air, unlike every other adhesive that needs it. If you squeeze some out on the table, it'll sit there forever.
