A’ve got a Minolta Autocord (without light meter) which has a leak problem, it looks like this:





First I thought that was a problem with seal so I replaced that, nothing changed. Then I replaced seal once again and pasted over clefts with black, non transparent tape, nothing changed again ūüė¶

Now I don’t know where might that leak come from,

Thank you for any suggestions.

I think it is a shutter issue.

Any chance that the focus scale on front is missing a screw on one side or the other?

, your links don’t register as actual links. I cut and pasted one, but that’s all I’ll do.

Check for any other missing screws. Spool knobs, focus hood. Check the feet for bending and cracks.

Important question with any light leak- does the effect stop at the edge of the image frame, or is it also in non-image areas? This tells if thel ight is coming from the front of the light box- shutter, lens board, etc.- or if it is from elsewhere.

Also open the back and put the film against the opening as if it was being exposed. See where the leak falls inside the camera. Including at the upper or lower film spool area- most often film gets fogged before or after it is in the gate for exposure. From what I remember of oyur shot (nope, not cutting and pasting again) it had the look of a film spool being the cut-off for the lower part.

From the squarish shape in the middle of the frame, and the position of the bright spot, my guess is it’s the bottom spool release knob or close to it. Does it show up on the last frame?

Ddandan is right there is a missing screw on the front, it took 5 films to figure out ūüė¶

Thank you very much!!

I will shot another film today to verify.

About right, five rolls. I think it took me four to figure it out when it happened to me? I had simply not re-installed the plate after doing some work on the camera. Drove me crazy. Tried new seals, taping the outside of the back in different areas, etc.

Great news.

I need to remember this for future reference.

There are many holes in TLR bodies that were drilled all the way through. These provide easy access to light if the screws are removed. You can see the holes inside the film chamber, etc. In the mirror box are other holes that come through.

For manufacturing, this makes sense. Drilling all the way through is quick, allows the chips from tapping to be blown out easily, etc.

Everything is OK now, I am happy.

What I did to find the leak:
I took a few LEDs from my bike lights, wired them with little bataries, put everything into the camera and checked in dark room to find if I can see some lite.

Big Set of Yashica 124G

Saw this big set of Yashica 124G on ebay… very complete system and truly speaking, I never saw such a complete set. The accessories are in very nice condition.

description by the ebay seller:

Where to start.This is the biggest complex set I’ve ever seen.If you want it all with one stop shopping, this is the set.

Camera is clean with all covers and buttons working,and there are many.

2 triggers for an option to use either to operate the unit.

Nistar Flash works and has 2 leads, 1 is coiled and flashed bright when triggered.Also has original direction book.Contacts are clean and non corroded.

There are viewing lenses 1 and 2 with their own leather cases and in plastic bags .

Yashinon  Wide Angle set of 2 lenses in leather case.

Yashinon Telephoto set of 2 lenses in leather case.

Alpex light meter #44456 was registering light readings and has leather case.Flip up light meter door works great.

Camrex Cambron Polarizer Filter B-30 looks great.

Peak Mono Tone Viewer very nice medium dark brown lens.

Yashika Square attachment I think is for field reduction and light/glare reduction

Metal mount,not sure what it is called but attaches where tripod does and has a vertical fist type grip with safety strap,shown in mostly folded for storage.

There is the Yashica original complete instruction guide/manual.There are so many papers on what to set camera at for specific subjects,what films to use and where and why,what speeds to set for different shooting modes and actions,Helpful hints and tips,what lenses, filters to use where and when.All kinds of information and I didnt get all papers into the pics,there wasnt enough room.

There is a brand new battery that I removed from package to test unit and then put it back into package.

This huge set is 20 pieces counting the carrying case but NOT counting the lens covers and such.

DIY Replacing Mirror in Old twin lens reflex cameras

This time, replace the mirror surface (mirror surface reflection) is the name of the domestic machine Ricoh flex VII.

Twin-lens reflex, so it is most similar to the structure, time does not change the Minolta auto code in Rolleiflex.

Mirror surfaces are then extracted in this way is usually degraded. Focus position is not changed even by changing the mirror surface of the structure because it is pressed against the stopper plate spring on the left.

To which the mirror surface is available, those sold for repair camera is generally very expensive.

  • This shop Kaleidoscope¬†House “Kaleidoscope old days”¬†were obtained by.¬†300mm √ó 300mm √ó 1mm ones (with seat) is ¬• 1,890.¬†There are also other stores that deal.
  • JUZON STAINED GLASS MARKET¬†are also covered.Sputtering mirror 300 √ó 300mm ¬• 1090 (reflector surface).
  • Since there is a possibility that you can get a close, we want you to search using the keyword kaleidoscope mirror surface (mirror surface reflection).
  • http://www.kaleido-japan.com/make/material/¬†I think it may also be helpful.

Cut glass is in the hardware store. It is sufficient for the cheapest ones.

It is a simple glass cutting than I had expected. I think the bend while pulling on both sides put the scratches in the glass cut it hang. Can not peel off the protective sheet until the end of the blue.

Repair of dozens of twin-lens reflex is possible with a single mirror of ¥ 1,890.

No doubt because it is so you do not put a face sheet of blue glass cutting shed.

You have put a protective sheet surface of the front side blue.¬†I’ll leave this up to the mounting surface of the sheet, so very weak.
This is a Ricoh flex, it is exactly the same procedure in the Rolleiflex.
The mirror is fixed by simply pressing plate spring. Then, peel off the protective sheet of blue.
Shiny. Brightness of the finder was felt more than doubled to experience.

I want to try so very simple. Finder of the old twin-lens reflex is to regain the glow of the time.

This flex Aires automat (with Nikkor).

Hood focus of many twin-lens reflex depart with four screws.

Severe degradation of the mirror surface. Is how the mounting plate is pressed against the stopper in the spring as well. Even if there is no movement of the focus to be replaced.
We cut a new surface mirror. Since the tip of the cut glass is not stable at normal scale, I will use one that does not slip if there is a certain thickness.

Cutting units of 100-yen shops, this is also useful as a mouse pad actually.

Here but have to peel off the sheet, those who do not have good peel.

So I tried to put Fresnel incidentally here buying.
