Yup, I can't be the first person to do this. I've not seen it done anywhere, but it's pretty basic. I just wish I'd done it a long time ago. The deep frames are far more challenging than mediums or shallow when doing any form of foundationless. I've tried several methods and this one is by far the best.
I've got no time or use for frames like this:
This is the quality of comb I get whe trying to go totally foundationless. Ugly-right up to the time it fractures-even with wires. Unreliable. No consistency.
Here are some of my other attempts:
Even in a strong mating nuc they don't reliably make good comb with a generious starter strip
Same frame after I hacked out the ugly. I found anything larger than wire encourages large cell building
Actually, any horizontal break or change seems to encourage drone comb
This a beautiful..right up until the time if falls out of your frame.
Even though this was attached top and bottom, it still fractures easily.
This was the inspiration for this design. A cut out installed in the center of a frame
drawn out and worked
I've fooled around with several designs. Who would think they would draw out the foundation before foundationless?
This on inspired my cell builder frames for times during the flow they want to built comb all over my queen cells:
It helps me avoid this:
Heres a frame of new grafts goin in the starter with a light draw on the foundation from the last batch. I get no comb on my cells with these frames.
Type depends on placement within the hive and flow rate.
