self made strap lug

neck strap, attached by usual way was not comfort for me.

I need neck strap attached at left side of camera.

so, I make strap lug from paper clip (steel nickel-plated wire 1.6 mm OD), and attach it to the grip body at the left.

now right side of the camera is free of strap, so it does not disturb me then I shoot portrait.

That's very neat. Just make sure it is strong enough!

Sorry, I would not trust my camera to a paperclip. I have been doing mechanic work and metalworking all my adult life. One thing I know, paperclips are some of the worst Metal available. if you want to make a strap lug for your camera, use a better piece of metal. drill rod, 01 or A2. And harden it. But not a paperclip, And Not on my camera.

Also, although there are some very good plastics these days, some of which are approaching the strength of metal, I would not trust my camera strap when it was connected to a piece of plastic. I would want something more substantial. the plastic was never designed to hold a lug at that point. I think more of my equipment than that. I Would rather put up with a little bit of inconvenience, for better security.

original lugs has a 1.5 square mm section cut (1x1.5 mm), and 1.6mm OD steel wire has a 2 square mm section cut.
so, paper clip is factor x1.7 stronger, than original lugs (ha-ha) (strengths has a quadratic dependence of section cut)
Yes, this steel rod possibly soften, than original lugs, so let's thing it is AS strong AS original lugs.

so, lets think, that this wire NOT from the paper clip, but regular nickel plated steel.
sounds more better?

used this kind of clip, but bigger one
http://myoasisofficesupplies.com/test/productimages/double-clip-15mm-small-.jpg
wire was bent as П shape and inserted in to drilled holes.
after that ends of П shape was bent as C shape, bur square, and hot-embossed in to plastic of grip body. some CA glue added and upper plate of grip returned.
upper plate make impossible to disassembling of lug.

it is really strong and tested.

it DOES hold 18 kilograms. (18 liters of water)
I will never test it until it breaks, because I have only one, but it really strong.

1.6mm OD, 4 times, 90 degrees, 1mm bend radius bent, 45mm long, drill rod?

That's not a paperclip. It's a binder clip. Huge difference.

Now you know why i was so surprised when you said you used a paperclip. what you used was equivalent to what I suggested. just because two pieces of metal are the same thickness, it doesn't mean they have the same strength.

I don't think you'll have much luck. Paperclips are intended to be fairly flexible, and they're typically poor quality metal that breaks easily. I used to break them all the time while being stuck on conference calls, just for something to do with my hands.

Drill rod, 01 and A2 are materials that have high strength when the forces are parallel to length of the material. The are very brittle when subjected to side forces and even more so when heat treated. Just think about that .030 diameter drill bit that you accidentally snap when drilling with a hand drill.

Grip for K-30 - I make it by myself from K-7 grip. (also see my signature below post )
it has D-Li109/D-Li90 or 4-to-6 AA compatibility (3 type of battery,yahhh )
but to be honest - I'm not using AA, only lithium.

also grip has a shutter button.

see the link below
