New gun - shaft/wishbone question

This one for the loop

For the wishbones, I don't know the name, but I think it is clear at the lower pictures.

Here you go:

here is a terrible paint diagram of how to tie that knot...the blue is the loop, the red is the wishbone and the last pic, the green shows where to pull the end through...very very simple knot..i like to burn the ends of the wishbone so they form little balls, that redices the ability to slip to just about zero

it works like a charm actually... i have a few stories like Marco's where i was able to change a wishbone or whole band in the water in no time...I keep about 3 extra wishbones in my dry bag and one tied in a square knot to my float line.

Sometimes I carry an extra band tucked in my wetsuit or clipped in my float.

The knot to tie the wishbone to the loop is the sheet bend.

There's also the double sheet bend, depending on how big of a loop you have to tie to.

Both work well, I usually do the double.

Does anybody have any experience doing it the other way around - i.e. the loop is of a thinner cord material, and the wishbone is thicker?

I don't recall what size dacron I used in this picture, but the loop is 600 lb. spectra. The dacron wishbone is about 2X the thickness of the spectra. I got the materials from Phil H., maybe he'll chime in.

That's the way I used to do it and it works fine. Loop 1.8mm, wishbone 3mm. If you think about it the loop has to be of thin diameter, because it's doubled up and tied in a knot which is inserted into the band. If the line was any thicker the knot would be too big to insert.
