A year ago I bought a lens that required the use of a flange. Since I had a Cambo at the time I had a friend enlarge the metal lensboard hole and drill 4 small ones for the flange screws. He took a loooooong time to get it done, and when I got it back I found that the screw holes he drilled were too small. Rather than wait another month or two, in my impatience I bought a tube of silicone aquarium sealer and used that to bond the flange to my lensboard. Now I need to mount the lens to a wooden board for my Ansco 5x7 and it turns out that the silicone does an absolutely fantastic job of bonding the flange to the board! SO good, that I can't get it off. Heading the flange and board over a candle flame does not melt the silicone to any appreciable extent so at this point I'm quite literally stuck. MPEX wants $25 plus shipping for a new flange, which I would gladly pay if it were not for the fact that I'm very cash-strapped for the next month or two. Is there anyone here who knows how to separate two metal items bonded with silicone aquarium adhesive? Alternately, is there someone who is willing to send me a flange for a non-Kodak Ilex Acme-Synchro #3 for the price of postage?
