I was describing my new home
made frame perch tool design to a friend and he furrowed his brow
when I mentioned how I used wood instead of metal. He was concerned
about a full frame of honey being too much weight for such a "light
duty" structure.
That possible problem was fixed easily with the next size down L
bracket being secured in each corner. You might need to chisel out a
groove for the bracket depending on how much wiggle room your frames
have to move back and forth while still staying snug.
