Author Topic: Simplex single lens holder "play" John Walsh Film God Posts: 2490 From: Connecticut, USA, Earth, Milky Way Registered: Oct 1999 posted 10-13-2000 11:36 AM                     I have a question on the regular, single lens holder used on the new Simplexes. On the two I'm using, the focusing knob is loose. You have to turn it about 1/8 until it starts to move the lens holder, and it does the same thing when turning it the other way. It makes it a litte harder to focus it quickly. How can I tighten it up? I'm sure it's not the knob itself; I've tighten the allen set screw on there. I've seen the exploded diagram (in the parts book,) but I couldn't see what would cause the "slop." Also, ours has the little lever to move the lens over (for mag or optical image centering.) When you are looking at it from the front, the lever can go to "12:00" position to "3:00" position. Which position is for optical, and which for mag?  |  IP: Logged Greg Mueller Phenomenal Film Handler Posts: 1687 From: Port Gamble, WA Registered: Jun 99 posted 10-13-2000 05:45 PM                        Watch the lens from the front. Move the lever from one position to the other. When it is the furthest away from the operator (and the analog track) it is in the optical position and when it is closest to the operator (and analog track) it is in the mag position ------------------ Greg Mueller Amateur Astronomer, Machinist, Filmnut  |  IP: Logged Brad Miller Administrator Posts: 17775 From: Plano, TX (36.2 miles NW of Rockwall) Registered: May 99 posted 10-13-2000 06:12 PM                     Much easier way. Remove the aperture. Rotate the lens so the image is pushed as far "projected right" as possible (so the analog track shows). That's your magnetic setting.  |  IP: Logged John Walsh Film God Posts: 2490 From: Connecticut, USA, Earth, Milky Way Registered: Oct 1999 posted 10-14-2000 08:47 AM                     Yes, of course. I should have guessed myself. Both ideas are easy to do... This particular problem is that it looks like the tech did not put the lever to optical when he filed the aperture plate. Now, you have to look at the screen and adjust it on the fly when changing formats.  |  IP: Logged
