hi, All. I swear I researched this last night, but I couldn't find exactly what I was looking for. I've read Michael Bush's recommendation on using the top bar of a standard frame and affixing a comb guide to use as top bars for a TBH. I just re-read that post (on the "Using foundationless frames" page) and I think I misunderstood the first times I read it; that is, that recommendation is for going foundationless in a Langstroth hive, right? Not a TBH, per se. I realize that the bars my husband and I made are simply not good enough, and I'd like to re-do all of them -- at least get rid of the 22 they haven't used yet! I thought of simply using the top bar of a standard frame (an inexpensive option), but it looks like the actual dimensions of that bar is only about an inch wide? (Because the bees crawl between the bars to access other frames) That would mean they are too narrow, and I should just find a friend with a table saw? The circular saw just didn't do the job.
