I've been doing comb honey for over 20 years. It is faster to just turn the wedge strips up and put a few 5/8 brads in them than using popsicle strips and there is no need to add wax. They last for years of reuse. The main thing is to have your hives level from side to side. Also the have a copper baster made for wax and it stays warmer longer in several beekeeping catalogs.
This is water cooled beeswax foundation press. I got it long time ago from Latvia. It makes beekeeping a lot easier for sure. There are also silicone molds that make beeswax foundation. You can check Ebay or Amazon I have seen them for sale there. Thank you
