I am new to beekeeping. I've always wanted to do it and finally decided last summer to get started. I decided I'd use the time between then and spring to research and build all I could so when spring came I'd have plenty of hives to fill and be an expert beekeeper. The woodwork is coming along well but the expert part seems just like college. It seems the more I know the more I know how much I don't know. On to the point. I purchased some used equipment from the widow of a club member who had unfortunately passed before I joined the club. Most of the supers had spacers in them and the lady explained that those were to use 9 frames in a 10 frame super. She explained that the bees would build the comb out further if you do that. So now I have two questions. What is the advantage/disadvantage of doing this? If I do decide that the fact that I enjoy working with wood is enough to prompt me to build my own frames (the cost savings certainly wouldn't do it) can I just make the sides of the frames a little wider to eliminate the need for spacers?
