Re: How much do you spend per year just on wooden ware?
I use a lot of plywood for other stuff, chicken coops, etc., but when I hired someone to make my boxes (didn't have time) I bought pine - 1x10 for deeps I think. Solid wood handles weather SO much better, especially if the cross-cut edge is not painted and is going to see ANY weather.
I dropped what, $300 or $400 on woodenware & tools last summer. Spent $60 on the wood and swapped out the labor for 4 nucs and 2 deeps, slightly imperfect ones, no fancy corners, but better than what my hive came with.
Bees in winter - new phenomenon, but I've got them... So far so good.
