last year I had 140 lbs of finished rendered wax. from cappings. I normally let those cappings drain for a day in capping trays. then the cappings are washed and rendered. My thought was to press the cappings then render.(cut out the rinsing part) Also all the slumgum can then be pressed also. Then if Im feeling overly ambitious I would make another for old wax, and the slumgum.
One thing about my conversion from 10 frame supers to 8 frame, as more supers go to 8 frame I have seen a consistent drop in finished wax. Also add to this my daughter does the uncapping by hand and she has also gotten better at it so that might have to do with the drop also.
