I’ve found various suggestions online, but none seems to have been from anyone who has actually used the puller. I would be extremely grateful for any suggestions.
I haven't tried your specific combination of tools and components, but in cases where the extractor tip bottoms out against the arm before engaging the spindle, I've found placing a 5/16" ball bearing (as found in Ashtabula-type bottom brackets; 1/4" is too small) on the end of the spindle and then having the extractor push against the ball will remove the arm. A dab of grease on the ball will hold it in place on the spindle end while you engage the extractor.
Bon chance!
