Re: Rollex Patent Film Holder

Hi everyone!

How many turns would it take to move from one frame to the next (using 6x9). I figured that the reason for my light leaks on the Maximar is due to the fact that I peep into the red hole counter of the rollex.

Thanks.

The number of turns varies as the film is advanced, because the effective diameter of the take up spool changes as more film is wound around it.

So basically, each successive frame requires less turns of the advance knob than the one preceding it.

Edit: Do you have an example of the light leak you could post here?

 

[sevo]

As he said - it is variable, so counting turns won't do! But there probably is something missing from that Rollex - black paint, a piece of felt or the entire light trap - which might be fixable. What type and generation of Rollex is it?

Peeping the red hole should not cause an issue unless there is a crack..if so then go look for some red see thru thin plastic to replace or glue over. But servo is right, the normal issue is the felt after all these years.

If u can't find anything wrong and want to experiment....

If u keep the same number of turns all the time, the gap will get bigger between frames plus u need to count the number of turns to the first shot. All that being said u could end up w/ frame less for the roll.

Just use another roll thru the camera and count to first shot and to next. It may turn out that the amount of turns though is not a full turn, so pre-mark your turning nob with at least quarter rotation marks.

Good luck

Thank you for the replies. Here's a sample of the light leak



and the rollex patent that I'm using.

Clearly not the red window, then: look at the shape and location of the leaks. If they were through the 'ole, then the location of the 'ole is where they'd be. My vote is for worn/missing light trap velvet, or even bent metal, the latter probably as a result of the back having been dropped at some point: as I recall, those Rollexes were pretty thin sheet steel.

Cheers,

My vote goes to light trap related as well. I c at least three distinct possible light leak locations.. Red window issues are usually centered around only the window area.

Thanks everyone. I'll do a flashlight test for light leaks and try to fix the seals or buy a rada/suydam, which are supposedly better(?). Cheers!

Rollex are worse than late Rada holders, simply because they stopped making Falz mount standard holders in the fifties while Rada/Plaubel continued into the eighties or beyond, modernizing them along the way. If you want a modern holder with little wear and a counter/transport system that is accurate with current 120 film, a recent Rada is the way to go. In period 1920-40 holders there is not really much difference - Rollex look more quaint and coarse, and have a tendency to warp (due to their thin sheet metal middle section), but they are less likely to have a broken pressure plate spring (and the counter on counter-equipped pre war Radas is useless with modern film)...

Hi all,

I got a Rada and it worked really well with the Maximar and the set up is very straightforward (unlike the Rollex). Thanks again for the help.
