I'm building my first ktbh and I have read so much over the past few weeks I can't remember it all or where I read it.

I think I need a spacer between the end of the tbh that has the entrance in it and the first top bar but I can't remember

how large this space should be. I think I read somewhere 3/8 of an inch but that seemed small. I tried searching the forum

first but had a hard time finding what I needed. I see where M. Bush used a similar space as an entrance but I'm drilling holes

in the end of the hive due to my roof design. I just want a piece of wood there to hold that first comb in position off of the entrance.
