Its been a while. Sold all my darkroom equipment. Gonna "focus" on 8x10 and 4x5. I have no room in my place and no more garage. Anyway, my 8x10 Korona front tilt is on 2 little button/ball like things. Makes sense, until the hole wears out after 100 years of use (no...I'm not that old). I stuck cardboard in there to keep it from loosing its tilt. Anyone have any suggestions on how to make this more usuable? Wondering if any of you woodworkers out there can give me a suggestion.
