The system is an A-frame type, based on instructions we found in the Catalina 22 Technical manual (the one distributed by the Cat 22 National Association). Many thanks to Dick King for his detailed instructions!
Here is a photo of the finished assembly, leaning against the boat.
The frame is made out of 3/4" steel electrical conduit, each piece about 80 inches long. The ends of each piece were hammered flat, with the opposite end of each one flattened at 90 degrees to the other end.
Holes for 5/16" bolts and clevis pins were drilled into each end, and the sharp edges rounded and smoothed.
Two short pieces were fashioned into adapters that could fit over the forward lower shroud chainplate eyebolts. The picture below shows how it all fits together.
We quickly discovered that these short pieces could not be hammered flat (and besides, hammering conduit flat takes a mighty effort). So, we picked up a massive workbench vise at Lowes (on sale for half price!--$35) and used it to flatten the adapter pieces. Simplicity itself!
Because the goal was to use the trailer winch to hoist the mast, we improvised a bow "roller" using a couple of "bar brackets" from the hardware store. These are the things you use to bar a gate with a 2x4.
Here is the assembled bow "roller". We added a piece of conduit so the trailer winch strap could slide freely.
The bow "roller," attached to the stem fitting.
I'll post more pictures later, but for an idea of how it all works, get a copy of the Technical Manual and read Dick King's article, entitled "Mast Raising." Thanks again, Dick! This rig worked like a charm.
