I've looked and cannot find the thread. Somewhere in this forum is a thread with pics of a stern mast support made out of wood, 2x4's and 1x4's with the 2 vertical 1x4's set in a V such that the ends rest in the trough at the stern and do not hinder tiller movement. I just wanted to thank that person. I'm going to post pics of what I threw together for my next mast drop, and I wanted to give him credit for the idea.
First is a 2x4 with grooves cut in the ends to slip over the stern rail so that the board is flush with the transom. Next are the two 1x4's set in the V pattern mentioned above with the bottoms angled so they sit flat on the floor in the trough, not blocking the scuppers, and the boards are just barely touching the adjustable back stay wires at the 2x4 level. These are held together with bolts and wing nuts for easy tightening. Next is another 2x4 cross piece set so it is a little higher than the bow pulpit. In the middle of that piece is a metal bow roller bracket holding a 4" bow roller. The bracket is secured to the 2x4 with 2 regular stainless bolts and nuts, including fender washers, and the other 2 bolts are stainless eyebolts with nuts and fender washers. The fender washers are not stainless, couldn't find them at HD. I used eyebolts to provide a tie-down anchor point on each side of the bow roller. The whole thing can be removed and collapsed without taking it apart.
Now to go get the pics I forgot yesterday.

I still need to paint it, probably white. The upper bar would also be a good place to dry life preservers, towels, etc.

I plan to use a piece of adjustable conduit with pintles welded on. Since I won't travel with the rudder in place, I'll just slip the conduit/mount where the rudder goes. Then put a keel roller on the top.

Heh, basically Catalina Directs mast stepper. Only it'll cost me around $50, not $210 shipped. ;)

I actually got the idea from my father's 77 Santana trailer setup. He also has the same mast holder on the trailer's bow stopper.

I've got the metal Mast-up device for both boats, and use it regularly on the C-22. My thought here, as I'm sure it was with the guy who came up with this plan originally, was to set up a temporary/semi-permanent, inexpensive device that would not hinder using the tiller, whether negotiating under bridges in a canal or getting the boat on the trailer. Once on the trailer, I'll remove the rudder and put the Mast-up in place.
I already had the lumber, so all I needed to purchase was the roller/bracket and the nuts, bolts, etc.
Edit: Ultimately, I plan to install the stainless pipe rig to the stern pulpit supports that DavyJ uses and is featured in his video, but that pipe is expensive.

Sounds a lot like my setup... http://littleboatiris.blogspot.com/2011/04/it-is-spring-again.html

I think that when I posted about it here, I suggested teh verticals be 1X4's. Then when I looked at my setup I realized I had it backwards. The transom scupper will take a 2X4 nicely. You may want to swap out those 1X4 uprights for 2X4's.

David - we raised our mast today, and during the process I got to thinking of your support system. When you do your lift, you will find that teh spreaders are barely forward of the wooden frame. Keep an eye on your shrouds, forestay and backstay to be sure they don't hook on the frame or the wood you left sticking out either at teh transom or on the upper board.

Thanks. The forestay shouldn't present a problem as it will be taking a load very early on. I'll definitely need to watch the shrouds and backstay.
I may be able to shorten the forks on the stern rail 2x4, have to wait and see. I may also trim back the top 1x4 so it is flush with the vertical 1x4's on each side. At a minimum, I'll probably trim them so the ends are parallel with the vertical boards. And I plan on adding a vertical piece on each side or the roller, angled inward.

Sounds good - hope it all works well for you.

I do like the way you locked it onto the pushpit. I wonder if conduit clamps could do the same without the ends sticking out. We just tie ours on with whatever we find lying around. You have a much more professional look than we do. I have never even considered painting ours.

When we went to raise the mast, I got out our knock-down A-frame and was going to take pics for you, but never did. A bunch of guys showed up to lend a hand and we just lifted the mast into place by hand. With 4 apes willing to help, it was easier than the A-frame.

I cut most of the material for the stern rail grooves with a circular saw, then trimmed it up with a jig saw. Made one goof, I should have left in the curved cut made by the circular saw blade instead of squaring it up. Might have snugged up to the rail better.
