How strong are they?


  Wrist strap, Lug-mount 

VOIGHTLANDER, of Rangefinder Forum, ordered a couple of straps from me and asked the following:
"A question ... your strap is it made from a continuous loop of leather or both ends are tied/hidden within the waxed thread. I need to know if it's the latter cos i will take care not to swing the camera around as the strap ends may just came loose."

There is a glued and stapled joint under the waxed thread. I've really pulled on these with my hands to test them, but I've been thinking about something a little more measurable. VOIGHTLANDER's question prompted me to do a test to see what the limits are. I first hung a vise and hammer that totaled 17 pounds. That worked fine so the only other thing heavier I had was an old monitor. It weighs 25 pounds. It hung there just fine, but the split ring was starting to deform.

At this point I didn't want to add more weight because I didn't want that much falling if it failed.

I think it's safe to say that if the camera you are carrying is starting to deform the split ring that you might not want to swing it around.

 Wrist strap, String 

I also have been asked "How strong is the string?" on my string attach straps. The string  that attaches to your camera is the material as the wrapping cord. I use a "monkey trap" design: The monkey wants something inside a jar, but when the monkey’s hand fits through the hole his clenched fist can’t fit back out. I use the same concept to keep the attach string from pulling through.

 The attach string is double knotted and the wrapping cord traps it in place. You can carry a fairly large camera with this arrangement. (Apologies for the slightly blurry pictures. I was using continous lights and a 1.5 second exposure. The camera was hanging free and was moving slightly.)

The strap is strong enough to carry my 5x7 Burke & James Commercial view with a 10" Elgeet lens.

I also simulated a camera drop with a 15 pound vise, which is actually heavier than the 5x7.

To test the strength of the attach strings I attached it to my 5x7 Burke & James with it's 10" Elgeet lens. On top is a Zeiss Icon Box Tengor and hanging in front is a Nikon F3 HP with motor drive, a Honeywell Pentax H1a, a Leica IIIc, and a Ricoh Diacord.

The total camera weight is around 20 pounds. I would recommend if you're going to carry all of your cameras with one neck strap, that you also purchase a neck pad. Just a suggestion.
