Yn-603 o-ring solution.

Hello all, I had another thread about the yn-603 and decided it needed its own thread. I ordered two sets of these and once I realized the lack of a locking lever I started looking for solutions. Having looked at how they lock (friction based) I tried finding something to mimic how the other devices work... I went with double stacked o-rings because they compress, have high friction, cheap, and have a good amount of holding power.

Double stacking them so far has been able to hold a 580ex 2 hot shoe mounted with zero issues. It's a bit of a tight squeeze to get the oring to compress enough to allow for the 603 to slide on but I think this is due to the high friction of rubber.

I invite people to test this out, I'm hoping that people can feel safe about its use instead of using the band around the flash housing. I can't post photos up due to my laptop being sent into bestbuy due to having screen issues.... This makes three times in a row

*I'll be getting some photos tomorrow so I can post as an example tomorrow. If anyone has an questions feel free to ask.

Update with photos now:

Hmmm. I figured peoPle would actually be interested in a fix like this but I guess not lol

Well I'm interested. I'm still using the RF-602s, but the Tx unit has the same problem - no locking mechanism (why they didn't include one, I will never understand...)

What size o-rings did you use?

this is actually a very nice solution. again what size did you use? also where did you pick them up? can you just go to your local hardware store and find them?

I'll get the sizes tomorrow. These ones where from some spare Orings for my paint ball markers I have. The big thing is that you realize that Orings can go bad. You can find them anywhere really home depot, lowes, any auto parts store. I tested it out first on my yn602 so it'll work for it yoo

The Orings are 14mm diameter 1.5mm thick but you can get get thinner ones. Really as long as they fit well and you double stack them. Just make sure make sure aren't super hard Orings to allow for them to flex

Nice one, can see perfectly now. I must try and grab a few O-rings

Thanks for takig your time to make this thread. I've been thinking of a solution to this as well.

Heyyy finally a solution! :O

Thanks for the tip, will use these on my rf-602 triggers.

You might want to ask a Mod to change your title for you, so that it shows that this works with the rf-602's as well.

Title isn't that descriptive.

I just had to order mine from Hong Kong on Ebay.

50 for about £3.50 with postage.

I can do that this afternoon. This should work for the rg-602s as well, I owned a set of them and first tested it out on mine when I realized that they didn't add a lock mech to the newer ones.

Maybe this should be a sticky somewhere? No?

Btw, I didn't have a clue what o-ring was so I googled it. Now I don't know which one to buy. Lol
So many. Even amazon sells it but it doesn't tell me the diameter or thickness

Edit. Ok I found one. http://www.amazon.com …TF8&qid=1328544​579&sr=8-8

Yay?

Are these specs ok?

Inside Diameter 14 millimeters
Outside Diameter 17 millimeters
Overall Width 1.5 millimeters
