Goal- To remove old epoxy or Loctite from the end caps of a set of Weyless roller drums.

I am having these rollers refinished by a local powder coater (and the durability of PC in this application will be a question, but things can't look much worse then the way the OEM finish does now). In removing the bearings and through shaft one of the drum's end caps partially pulled out of the drum's end. Si in for a penny in for a pound... I tapped off all the end caps (not hard at all to do) and find the residue of a bonding material. Brown and hard with drips running down surfaces. So this material was a liquid on it'a application. I was able to scrape (with my Swiss Army knife blade) the residue inside the steel drum's outer area enough for me to feel good about this being ready for reassembly. But the end caps are Aluminum and the residue is MUCH harder to chip off. Much harder. So my thoughts were to try a solvent.

Any thoughts or suggestions? The last set of Weyless rollers that I re bearinged (but didn't refinish) didn't have this end cap coming adrift issue so I have never dealt with this aspect.

BTW the PC guy thinks the sand blasting and paint will run about $45 including any masking needed. But now that the situation is different (I showed him the complete/assembled roller) I'll revisit him for his preference to what state of disassembly he wants to work with. Andy.
