  1. Re: Schneider 150/265 Compur Missing Locating Screw

    Thanks people. You set me straight. If I bought that I would have just another repair project on my hands. I already have a backlog of projects. Besides I think I'd rather have someting older like a...
  2. Re: Schneider 150/265 Compur Missing Locating Screw

    Thank you. Honestly I don't have the lens yet. Before I pull the trigger, I notice it also doesn't have the mounting ring. I bet finding another ring would make this lens a bad deal by the time I...
  3. Schneider 150/265 Compur Missing Locating Screw

    I have a Schneider 150/265 convertible Symmar Technika in Compur shutter. The shutter is missing its lensboard locating screw. The one that has a shoulder on it that sticks up to drop into a little...

    Re: Gossen Luna Pro Repair Question

    As a final addendum on thee Luna Pros, here's one thing I've learned. On the low range in a room with only a 60 watt equivalent CFL bulb, or in a dimly lit daytime room with no lights on, the...

    Re: Horseman 8x10 Homemade Tripod Block

    This project turned out exceptionally well. I'm convinced it is sturdy and operative. In retrospect there is one thing I would have done differently. The question being, can this brittle plastic...

    Agreed. Although good luck finding hobby shops any more. Might have to go to Hobby Lobby, although last time I was there looking at hobby wood it was piddling poor pickings compared to what hobby...

    Horseman 8x10 Homemade Tripod Block

    It's been about 6 weeks when I did a little research and got an Ender 3, the plain basic one, open-box for about $150 maybe. Had never seen a 3D printer before. So I got busy studying Freecad. I...

    Re: Gossen Luna Pro Repair Question

    No need. When I first started checking out the meter a few days ago, I noticed all the readings were about 1 stop over-exposed. And the battery check was about a quarter of the way up into the red...

    Re: Gossen Luna Pro Repair Question

    Got it calibrated perfectly for 357 batteries that had some use on them and were down to about 1.45-1.47V. Since it has no voltage regulation, it will swing between about 1.3v when the batteries are...

    Re: Gossen Luna Pro Repair Question

    Thank you Brian. Thr schematic is so small on screen I can't get a good look at it. But I am prone to take your word. The meter is off when the switch is in neutral, which is what I'd hoped. I just...

    Re: Gossen Luna Pro Repair Question

    Thanks. I've already seen that. As far as I can see it says nothing about the "switch" being anything more than to un-trap the needle so it can swing for a reading. It gives no hint that it actually...

    Thank you for this link. If I understand it right, most common red LED's are 620nm and can fog paper. But apparently if the red is 660nm wavelength, then this is about as pure red (and safe) as a red...

    Re: What's With the Rodinal? Can't Find Any

    Here's what I don't get. So, the story is Agfa went out of business. Then Adox acquired the rights to the formula. That implies exclusivity. So why would Rollei or anybody else be producing the EXACT...
