Hello, Looking to make tbh swarm trap and nucs. Any advice on how many 1 1/4 and 1 1/2 frames and length of box would be great. Thank you for the help.
you might try one like Robo's design using a sonatube just modify the measurements to fit your topbar length.

I'd go with 1 1/4" spacing since you will be expecting them to put brood in first.
