HELP! I TOOK APART MY CAMERA BEFORE I KNEW THE SERIES WAS INCOMPLETE! In all seriousness you're doing a fantastic job! Great videos, keep up the good work!
A fantastic series Sam, I enjoyed it very much. It delights me in a similar way to some other channels on mechanical wrist watch repair, and has that sort of Bob-Ross-of-repair-ness! The production quality was a real treat. It was very interesting to learn about how an SLR works. My personal camera repair journey has been with screw-mount Leicas and their copies/ clones / homages. It is interesting to see the similarities of the Leica focal-plane shutter to the shutter in the Pentax. I greatly look forward to future videos!
Thank you so much for the in depth explanation in your videos, I have had my k1000 back and forth from a repairer so many times I want to give up, now I feel confident to get it fixed to a decent working standard 👍👍
I had just bought the pentax k1000 and badly needed a video to understand it's mechanism when i found that you have posted just that day, i love these...
Thanks for the awesome videos. I have been getting a bit into camera maintenance myself but am still doing babysteps. My background as a technical designer is helping me a lot so far to understand how the cameras work. Your video series is one of the best I have found. You go into depth and teach a high standard and focus on longevity. I see a lot of people simply pouring oil or iso into their cameras which seems like a short term solution at best. I must admit that I am really impatient to see how you calibrate the lightmeter and shutter speeds on that pentax. Do you have any books/courses/webites to recommend for learning about camera maintenance?
Thanks for the comment. Glad you're enjoying the video. The last video got out on the back burner for a bit. A combination of fatigue and summer travel. I still intend to publish it, though. For learning materials, I've mostly used an amalgamation of service manuals, forum discussions, and UA-cam videos. Part of my motivation for making this video series was to provide a more coherent picture of what a complete overhaul of a camera looks like.
@@SamsCameraBench Appreciate you commenting! And yes, you are definitely acheiving to show a well done overhaul. I have a similar approach to finding all the information but there's often questions that pop up to which I can't find the proper information. Anyway keep up the good work man :)
Great videos! On this K1000 I just found the battery test (ISO 100 + Bulb) sends the needle upward. The rest of the time is gently vibrates around the center and doesn't move as it faces different light sources or apertures/shutter speeds are selected. So the needle isn't 'stuck' because it does move for the battery test. I cleaned and checked wires at the bottom and checked for corrosion and there was no cable detachment and no corrosion. Seems like I may have a broken element from your chart on the process of moving the needle? I am going to try a silver oxide battery despite the positive battery test when they arrive and then investigate other issues.
Based on the direction of the needle, it sounds like an open speed or aperture resistor or one of the CdS cells has shorted. If you can get your hands on a DMM, that will really help hunt down the culprit.
Hi Sam. Thanks for the great videos!! Thanks to you I managed to get a Pentax KM working. The meter that was stuck in the plus direction now works but it gives overexposed values. I compared it with a K1000 and also with readings from a phone app. Do you think we can use regular 1/4 watts resistors (instead of Pentax ones) to try to calibrate the readings like they mention in the service manual? Many thanks, again!
Hi Sam. Find your channel recently and love it. I'm just repairing my Spotmatic SP that have a light meter issue.The Needle goes up all the way and only at 1/500 or 1/1000 it downs a bit. Battery status check level functions fine and needle level off position are ok too. Also I checked resistance from the cds cells and they are reacting to light ok (8k at ev4). I think is the shutter selector, but can´t find anywhere the resistance values for this model in order to test it. Any help will be much appreciate it . Keep going with the great content.
Yeah, your Spotmatic meter is similar to the K1000 but a little different. Mainly it doesn't have the aperture resistor around the lens mount. It uses stop down metering instead (if I am remembering the model correctly). The troubleshooting is roughly the same. Check the components individually. Check for corroded wires and bad solder joints. Clean as much as you can. Then cross your fingers. I don't know the exact range of the speed resistor but I would guess that it goes from a few kOhms to hundreds of kOhms. If you can't disassemble the speed resistor, you could try spraying contact cleaner into the gap then moving it back and forth. That may be enough to get off any oxidation build up. Good luck!
Still waiting for the Part 8. Don't leave us on a cliffhanger!

Amazing details! Would love to see how you reapply the skin
This is why a CLA is worth every penny. Awesome work.

Looks easier than servicing my watches
Lol, it is.
Thanks for this video
Great explanation of how the metering system works
One time I took apart a bread toaster trying to fix it. I was sure that that mis-adventure was going to be replicated in your vid.
I zapped myself on some flash capacitors in my MZ-3 video. Maybe that would satisfy your schadenfreude, haha.
@@SamsCameraBench Haha, that was the way I figured out my Metz 60 power box was working after all.

When will be the next part for calibration will be released 😅
Has anynone ever said you sound like Matt Damon, great videos!
Haha, you're the first.
Cool video Sam! Is there gonna be a video on pentax mx repair?
Hopefully! I have one on the shelf that needs work. Just not sure when I'll get to it.

@@SamsCameraBench I am going to do just that, we'll see how it goes

Yeah, I've calibrated them with regular quarter watt resistors. Buy a variety pack and try a few values until you find what you need.
