Quick question, would you steam bend part of a new stem or cut to shape?
I have steam bent completely new stems, but for a repair of about 1 foot of the stem or less, I have cut the curvature in a board. Take a look at "The Wood and Canvas Canoe" by Stelmok and THurlow, page 166. TM..
Depending upon how tight the curve of the stem is, you can usually safely splice in a section 6 to 12" long shaping it out of a straight board. The splice repair shown in the book does work but its not as good as it could be.
The attached photos kind of show how I now do most of my stem splices. The red coloring is just to make it easier to see the laminate that is used to reinforce the relatively short splice that is used on the stem. Its all glued together and makes a very strong repair . If you feather the edge of the laminate, match the grain of the old stem, and stain the color to match, the repair is extremely hard to see.
I got my 1913 OT Charles River CS on Nov. 1 and picked up gunwales and other materials for Jerry Stelmok and tools from Rollin Thurlow in early February. I slipped into Maine on a Saturday so we could all social distance and I didn't have to quarantine on my return to Vermont. I started working on the stems in mid March when I bought my first 8 foot length of Ash. I have 4 feet left of my second 10 foot board. I relied on The Book, these posts, and the video by Mark at Nomad Boat Building at . My latest iterations are far from perfect but they do connect where they should and may be as good as I get. Nothing's glued or nailed together yet and I can still tweak things a little to get a better fit, but I'll take any suggestions for ways to improve on this. Just so you can share my pain, I've attached a shot of earlier attempts that I threw out as I learned. Just to be clear, I'm confident that the technique Rollin lays out in the above post is much easier, more precise, and doubtless just as strong.

I could never get the bird’s mouth correct. I just started doing this.
Basically epoxy and screw a thin piece of wood to be epoxied to the inside of the stem. I also toenail a screw through the angles of the repair piece and stem.
I have done dozens of them and no failures.
Rollin, that is awesome!!!!!!!!!
