Hello Gary -- Following another blog post, I tried making a replacement for the paper/fiber bushing. A white/translucent Fuji 35mm film "can" looks just about right. Cutting a strip carefully to the right size, matching it to the existing fiber bushing. It's a great replacement for the paper/fiber bushing, perhaps a little thicker, which should help those who cannot lock the center column.
