Truth be told, in all my years and messing about as a hobbyist, I am unaware of anyone with such a wide range of intricate knowledge and ability. Rock on!
Thanks for the fond (now at least) memories of working on this kind of stuff in the 80s.... the 1", the D2 machines, the awesome Digi-Beta , the SX , the many Beta & Beta-Max..... daily stuff i powered through on a daily basis for my employer in a TV station. It felt so good to pile in an endless stash of new parts and stuff on the mech deck & after an alignment the thing fantastic great pictures and sound again whereupon i'd write up the machines log knowing i'd see it again maybe a year later. Those days we didn't have to think of being given the "you're position is disestablished don't come Monday" speech and the thought oh hell how to pay the mortgage.... Yep i like this gear and the Panasonic DVCpro stuff some of the Current Affairs dept shot on.... its all a memory now and the place is now cutting over to cloud storage so we won't even have to ever replace Raid hard drives on a regular basis.... i guess they'll come to me soon with the same old "you're position is disestablished don't come Monday" again any day. Mind you the mortage is paid now & i guess i can do something else till the pension kicks in....
For just these cases, I made a small switch box with two momentary DPDT push buttons - cross coupled, with a PP3 9v battery. I could then drive the loading motor forward and back at will. In some cases, removing the head drum gave a better view of the transport mechanism. I also used a test tape with the flip-up removed. Foreign bodies such as a grain of sand in the mech was quite common especially with the overly compact DV camcorders with their paper thin plastic gears, and metal levers little more than tin foil ... problems just waiting to happen. A jamming mech can be a nightmare, usually solved - eventually, by just staring at the damned thing until the 'not obvious' becomes apparent ... you're then left wondering 'why' it happened, because under normal circumstances, it shouldn't have.
My Sony EV-DT-1 Trinitron TV with Video 8 recorder has the same tape mech. The only issue mine had was when ejecting the tape it would slip on the rollers and not come out all the way. I had to adjust the metal plate which then made the rollers press little harder on the tape. Seems to work fine now.
I had this exact model, but it was beyond repair. I also have the camera that came with this unit and the tuner. I really want to get another EV-C8 just because I like portable VCRs and such
I work on bicycles for a job at a bike shop and at my house, I'm currently working on a "Walmart" bought bike with cheap grip shifters I'm in the process of receiving a set of vbrake trigger shifters to make it shift properly like it should
I still can't help but admire this technology. Tortuous and flimsy but also elegant in the level of precision achieved that is required for it to work. One can't help but be amazed that it works so well e.g. how the tape manages to stay exactly on the path it's meant to be and the rotating head manages to track the data tracks. Data tapes are still being used and continue to be produced so this technology may yet resurface, who knows?
Similar thing just happened to me. I had this Kenwood DAT unit that was put up in the closet in the top shelf for probably 10 years and I totally forgot what the symptoms were when I quit on it. Sometimes you have to take a break and come back to it otherwise it is going to get thrown. Just tried it again about a week ago out of curiosity and the tape went in and loaded half way, then the sound of gears stripping. Then I remembered why I had stored it. Was not worth the time to fix since what worth is it to me if it was fixed? Kind of like an 8 track player.
I have a question and would like to ask you about to restore a GE floor tube radio nearly 90 years that I cannot find a schematic diagram. Any advice of your is greatly appreciated! How can I send you a photo?
Do you do commissions? I watched your video on the dvl-700 laserdisc player on replacing a belt. I can't even get my tray free so I can't do the rest of the tutorial. And I'm afraid I need help. If not, is there anyone you'd recommend?
@@12voltvids do you see those pins on 12, 4 and 8 o clock around the video drum(pins almost touch the o ring gear) ? the pins had tiny plastic rollers that hold the big o ring (gear) centered/in place , i think those broke and went missing
@@12voltvids another thing that would come to my mind is , you know once the ring is in loaded position there is a tiny *nub* that moves into an indentation of the O gear to lock it in position, maybe that engages too early (missalighned teeth) and that stops the O gear from its rotation
It will come right in the end but I agree sometimes a fresh look after a rest helps . Why bother it’s the Hunter gatherer in us we want it to work again.
Sometimes it's better to just leave it on the shelf until you are in the right frame of mind. I'd have got so far and said F it and tossed it in the bin...... I have a shutter to change on a canon EOS, the shutter is on it's way from china, I've watched the tear down video 9 times. Let's hope I am in the right frame of mind when the shutter arrives....
Second floor open window... Designed not to be repaired. It looks like surgery and we are in the gallery. This is going to bug you until you figure it out!
What this little pos? It hasn't worked since the late 80s when some rocket tried to clean the heads with a qtip. This was actually a rental unit from the shop i worked at and it was tossed

Because you are just like me. You like fixing things. I am with you brother. I totally get you. Cheers from Portugal.
Summed up perfectly, Rafael. We just can't help ourselves. 😊
I actually feel bad for the factory workers that had to assemble these. The miniaturization. The amount of screws and cables.
Probably put together by robots.
Sir you have the patience of a saint ,great channel 👍

Don't lose faith Dave. You have the ability to diagnose and fix it. Thanks for sharing #StaySafe.

WOW, I hate compactification, it makes things soooo very difficult to work on!
Spare a thought for watchmakers. They've been doing surgery on tiny mechanics since the 16th C.

Watching you take apart and repair old technology is oddly satisfying.
I still can't help but admire this technology. Tortuous and flimsy but also elegant in the level of precision achieved that is required for it to work.

Busted gear anywhere?

It's like PCB origami.
have you ever repaired a 1974 Goodmans module 90
Because we love Meca-Electronics. I love your videos because of that, I am entertained. Thank you.
Because you'd go nuts without something to work on.
if you really want to fix it and cant get parts , the ccd-v8af camera has the same tape mechanism and its not super expensive on ebay
I have a v110 which is the same mechanism too.

@@Dr.-Smart the rollers are there. I had them all out to inspect them. They appear to be ok but the loading ring still sticks.

I hate that. Especially youtube. I support you to the fullest.
Could it have some piece missing? It is strange how it jams.
Or something broken.
Why You bother is because You help me see the importance in life, Fixing stuff enjoy learning.

Sense of accomplishment when it does work again. Even though it shouldn't.
Weird. He just posted a new video, and it's set to private now. Something about, "You Gotta Be FUGA Kidding, " whatever that's supposed to mean.
It's not private. Go watch it
love your stuff

I understand.... btw, I admire your patience. I would have thrown it into the bin right away.
It would be neet to get it running just to watch it load the tape. I don't really have any use for it. Some day i will waste more time on it.

Thats an over-engineered piece of equipment
Repairing stuff is our addiction.
Dave i'm sure you like torturing yourself lol.
It's likely full of dead capacitors, not worth it.
Remove the heads and show it the bin.
Looks like a handful of bull$hit to me!!

@@lesoram6236 it was in a box in my storage unit. Its next stop could be the recycle center.
