So here is an improvement to the Lynx. I replaced the rubber nubs with a machine screw and friction nut, so that the friction at the top arm can be dialed precisely for the rope dia. The bottom tending arm and larger bollard improves tending and keeps rope on the correct enter/exit path...
The 9mm I have is stiff to tend, until it is flattened a bit by the Lynx, I would say it is not quite as grippy as the beeline, but will do SRT if some tension is held on the rope below the device.
Here is a 3 arm OAR I forgot about, and found on rope when I was searching for the 9mm. You...
11.7 is too fat for the lynx, however I did make a device 10+ years ago using the next size larger link, which was essentially a ZZ with a proprietary adjustable headstock which did SRT/MRT on Tachyon.
The beeline is a very tough rope, which holds its shape well. My short piece has been...
These size 60 ss links lend themselves to the 10mm beeline. The top rope wrench style link is 30 thousands narrower gap than than the lower links, which causes it to engage well.
I remember seeing gas at 18 cents per gallon in the later part of the '60s, but that evidently amounts to over 3.00 dollars in todays valuation. In fact it is remarkable how stable gas prices have remained over the decades, when you factor in inflation. We are exporting less from the Middle...
Based on my experience making a link device, I would think a stronger top spring could resolve this problem. The "Pulley Rack" I made did not in fact rely on a spring, but rather an adjustment which moved the top link against the rope.
