Problem Re-shafting a Second Time

Hopefully you have not taken off too much shaft to use an extractor.
Slow and patience is the key

Huh? This thread has nothing to do with backscrews. My inquiry is how to break the bond created by modern epoxies.

Most epoxy breaks down around 250 degrees.
Use a torch to heat a 1/8" steel rod, red hot , wait 5 secs., insert the rod for 10 secs. pull the rod, and with the shaft clamped in your vise pull the head STRAIGHT off.
You may need to do this several times. Patience is required here.
Another option is to drill the shaft out. This is also difficult because you have to drill perfectly straight.
Hopefully once a graphite shaft is installed in a wooden head it is permanent.
