I recently built two top bar hives to go along with my large Langstroth hive in my backyard.
On May 15th I drove over to Navasota, TX, and picked up two packages of bees with health young queens . I installed them that same day and left them pretty much alone for 9 days or so. I inspected to ensure that they were building straight comb and in the orientation that I wanted. “Yessiree they were doing good.
Today, June 1st and I opened them up again to see how they were progressing. I am again impressed. They have built out to the 5th bar on both hives and appear to be happy. Below is a picture of bar 5 in my hand.
On most of the top bars a routed a 3/8 inch wide slot about 16″ wide, centered in the 19″wide top bar. On 6 bars for each hive I switched to a 1/4″ router bit and did the same. In the 1/4″ groove I used some beeswax cell material cut into a narrow strip and used hot beeswax to hold it in place. It appears that they are using it as a reference. I spaced out the bars with the base material alternating the standard bars with the 3/8″ grooved. On the3/8″ grooved bars I have a 3/8 X 3/4 spline glued into the groove and painted with melted beeswax. It appears to be working.
Top bar number 4 is really looking good! Sorry about the washed out photo….flash was a bit too bright.

Nearly full width and deep into the box. Sun was a little bright and the flash washed it out a little.
The second TBH was almost identically drawn out so I didn’t photograph any of the comb. The next photo shows the top of the hive with the corrugated plastic roof removed.

The bars fit flush across the top made of standard 1X2 lumber so replacement parts won’t be a problem.
The bees were gentle and quiet. I did use my hood and a little smoke but no gloves. Soon…I will share a story of my stupidity and a veil filled with angry bees. Wonderful lesson learned.
Tomorrow is my planned day to open the Langstroth hive and extract honey. The two top medium supers are packed full and I should have a bountiful harvest.
