Re: uncapping for 100 hives
A chain uncapper, fed into a cappings spinner, drained into a heated, water jacketed, settling tank (sump) works rather well, although the cappings tend to become drenched in honey all too soon. I have all Maxant, but have never incorporated my chain uncapper (a mentor did).
'Hot knife gets really old with 60-75 hives and 2-300 supers. Cappings get drenched, all the same.
Nice concept, though...If I were building UP, I might dust the uncapper off...
After 40 years of beekeeping, I've come to realize that the bees can fix most of my mistakes.
