Just picked up a 1976 25 trade wind locally, found on craigslist and we are in the discovery phase of AS ownership. I won't complain too much about floor rot, roof dents, leaks etc. but I did have tremendous luck in straightening out the entry door which I wanted to share. It was an inch or so out top and bottom, I think from opening while being towed.
I removed the door and laid it face down on a table holding up the top and bottom up with blocks of grey high density urethane foam left over from my kayaking days. Then I got a big c clamp and held the door to the table near the latch, protecting the door with a piece of wood under the pad of the clamp. I proceeded to tighten the clamp making sure that the door didn't dent from the foam holding up either end. I then picked up alternatively each end of the door bending it back to shape. The cool part is I used the screen door to check my progress after removing the clamp. It is now 95% correct and closes perfectly. No inner skin removal etc. Sorry for no pictures, it was over in 10 min.
Our next adventure is a ton of roof dents, we just removed the inner plastic cowl inside the front of the trailer and tomorrow I hope to have a lucky session at least with the simpler dents. I do have admit my wife and I are metal smiths and I think that its why we were drawn to the AS, as it is a work of American Industrial Art, especially tho older ones.
Thanks for the great forum,
