Rear standard and base frame for 5×7 conversion back. I use a stone ‘reference’ table to check parts for flatness. The Lie-Nielsen rabbet plane in the back is perfect for truing up small parts. Excuse the crappy 5am picture…@_@
I came close to selling my first home made 5×12, but instead decided to make a conversion back for it so it would see some more use. I missed using this camera and have always wanted to try 5×7, so I started making a new rear standard for it this past weekend.
