Everybody thanks for the help it is appreciated.
Pearl, that is a good idea and I might give it a try if nobody makes one for sale. I am lacking in the metal working skills and tool departments. However, I do have several subcontractors who I think could make it happen.... For the right price.
Bamboo, thanks for the contract information. I have Jacks info and have communicated with him via email when he came out with his book. Back then he refused to sale his sleeves.
Wolftrail, thanks for the options but I have built bows with most of the systems on the market, including Big Jim's fiberglass, the sleeves mentioned above (as well as Pine Hollows), Robertson's Connexion, round metal and fiberglass sleeves described in early Primitive Archery articles, and a couple with the Bow Bolt. Before you ask, yes the Bow Bolt works in selfbows, both the 68 and 65 pound bows are still in use seven years later.
I had one of Jacks Harrison's bows around fifteen years ago and had forgotten how well his sleeve system worked. I was mostly looking for a machined sleeve like his and wanted to see if I could make it work as slick as he puts them together. So far the Bow Bolt is my favorite but the handle ends up a little big for my liking, but then so is Harrison's.
