special order bushing for rope wrench

[ssurveyor]

I have posted this elsewhere and thought I would post it here also. I have had a machinist make me a dozen sheaves for the singing tree rope wrench, at a cost of $20 per sheave. I am willing to mail them for anyone interested in having one (or two) to try, for my cost plus shipping ($5 US, $10 worldwide). They will work with the 5/16 quick release pin also. I could supply the steel link, or SS 5/16 bolt and lock nut, but that would be extra.

Thanks, Gordon

Dogbone RW

The sheaves pictured are sold out. Here is my latest prototype mid-line dogbone RW I designed/made, which has a sheave at the lower friction point. The roller chain link swivels back to allow the rope to be installed (Dogbones not for sale) The RW concept is Kevin Binghams invention.
