I just built our first Warre. There is a picture of it on our website under the "News" tab. I'm making top bars today and want to know if they should be attached or not. I've read that some people do and some don't. I was thinking of cutting a slit in each end of the bar that would sit down on a small finishing nail driven at the correct spacing in the rabbet. Or is this necessary? I know the bees will glue them down pretty fast. Advice? How about it, Cacklewack?
