Re: comb honey without special frames???
The benefit to the Ross Rounds system is that once the bees finish their part, you can pop the comb out of the holder, just add the top and bottom caps, and you are ready for market. If you don't use the Ross system, (or a competitor) then there is more work for you to do to prepare cut comb for sale. Of course, you need to weigh time vs cost to decide what is best for you.
If you chose to just use foundationless frames and are concerned about supporting the comb, some users here have recommended wiring the frame using fishing line. You can then easily cut the line when harvesting cut comb and then pull the line out of the comb.
