I read your excellent post about modifying your Bell & Howell into a single-focus unit. Inspired by what you wrote I have ordered a Bell & Howell in hopes of replicating your modification. I was hoping that you might be able to provide some additional info on the customization you did. Particularly details on the 'multi-start thread' front housing you had fabricated in order to reduce the number of rotations required for focusing. Did the machinist you worked with create any schematic or CAD file? I am grateful for any/all info you could provide, or just any advice or observations in making & using your B&H lens. I'd like to document the process it and post it back to the EOSHD forum (provided I can do it successfully). Thank you for your time and consideration!
