Here is a modification that I made to Kevin's idea for the use of a pin to make the Rope Wrench mid-line attachable because like previously mentioned, all my ropes have spliced eyes on both ends so set-up was difficult.
The pin idea works well but I didn't like the force of the rope on that smaller diameter pin. One idea would be to install a larger pin, however, one would have to drill out the shoulders to accommodate the larger diameter. Another idea I came up with was to machine a bushing to go over the pin that did two things, 1) it maintained the original diameter and 2) it created an even weight distribution or shear force across the entire diameter of the pin. The latter was my biggest concern and it was solved by the bushing. The bushing fits tight therefore it cannot rotate and with a rated pin, i.e., known shear force, this is a much stronger set-up than a pin alone.
Two points, 1) yes this adds another piece of gear and something that you can loose, 2) I will be replacing this current pin with a rated pin of a know shear force. Bottom line, I'm fastidious enough to be careful with my set- up to hopefully not loose that extra piece of gear, i.e., bushing, and this gives me a much stronger set-up vs. the pin itself without the bushing and lastly all is midline attachable.
