In 50 years among the Bees CC Miller used wood sticks also. He did not drill holes in the frames. He simply cut them just short the hight between the top and bottom bars, then to secure these by dipping them for bit in bees wax then someone put some pressure on a board and press the sticks into the foundation a bit. He used 5 or 6 of these 1/16 by 1/16 "splints" on each frame. I plan to try this useing the bamboo sticks.
