I was given enough foundation to last a long time but when the time comes, I was wondering if you could not just make a casting with plaster of paris. I think I saw something about a hinged box with molded plaster of paris both sides. seems like that would be simple enough.
"Keeping Bees" by John Vivian explains and shows the mold you describe.
but nothing is ever as easy as ity seems when you try it.
You hit the nail on the head, I messed with try to build one (actually 3 by the time I gave up).
Thanks to Michael's insite, I think my foundation days may be over.
