Replacement Center Column Bush for Marchioni

From: Richard Karash, Feb 14, 2010

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.

However, your headless column has a slightly larger diameter, so I have the opposite problem: I need a thinner bushing. After trying several approaches, drawing the plastic tightly over the sharp edge of a good scissors planes off a little at a time.  After a dozen strokes, I have a new plastic bushing that is just right...  I can slide the column up and down, but a moderate twist of the knob locks it down tight. Thanks for the excellent support of Tiltall. -Rick

As is, it should help those with slipping center column.
