Looks pretty good.
Matthew stole your show. Cute kid.
Two problems I think you will run into. One, with that gap which looks like it is about 1/8", a bee can flatten out and craw between it. I don't know if they can craw all the way threw but I have pulled live bees from gaps less than 1/8". They were propalising the gap.
Which brings me to the second problem, with a gap, they will propolis the frames together.
On my OH, I have my frames hanging in slots. After the bees have been in there a while it takes a hive tool to pry each one out and there is only one inch of glued wood to hold it in place. Not 18" of propolis glueing them together.
Good luck with it. Hope it works for you and I know you will learn a lot from it.
