tbh , how big of a crack is to big?

[jpelley]

Made a tbh out of scrap wood and it looks alright except for the seam around the bottom board. There's a hair to an 1/8th in gap and was wondering if it would be OK. Figured the bees would fill it with propilis if they don't like. What do you all think?

1/8th inch will be filled with propolis. 1/6th inch may be used as an entrance....

I agree that the crack is unlikely to bother the bees. If it bothers you, squeeze/drip/brush some glue into the crack, cover it with a liberal amount of sawdust, then use your finger to moosh the sawdust into the crack.

Thanks guys, like the sawdust idea!
