Doweling Ash Keelboard

The Keel board of my small sailboat snapped along the grain during some rough handling... oops. Anyway it is broken in a non load bearing area and I am considering using dowels to get it back in action. Ash dowels are however hard to come by so I am looking for recommendations on another species that will pair well. The joint does not need to be overly strong but will be under some tension load when in use. Any suggestions?

welcome to the forum. i think any hardwood species will suffice, since it will be covered up. expect the glue and finish to be the greater issue. i'd use a good waterproof glue or epoxy, and whatever best finishes for wooden boats. a good clamping jig may need devised to apply good pressure while the glue dries.

Thanks, the clamping jig may be the hardest part assuming I can get the dowel holes aligned.

Is there a lot of sheering force on the keel too?

Steve- Yes there is tremendous shearing force but the area in need of repair will see none of this. This is a swing keel and the bit that broke is simply there to offer a place to tie a rope to hold it in position. I am not at all concerned about the strength of the bond.

We have an introduction section where you can say a few words about yourself. If you fill out your profile in your "User Control Panel", you can list any hobbies, experience, occupation, or if retired…from what, or other facts. You can also list your general geographical location which would be a help in answering some questions. In doing that your location will show under your username when you post.

What is the thickness of the two mating sections?

It may be easier to cut a crossgrain spline out of hardwood. It can be ¼" wide by whatever length you need. Then you don't have to match up holes for a dowel, but rather cut a slot (which can be a tad longer than the spline), and use TB III, or a urea-formaldehyde, or phenol-formaldehyde glue. You can drill holes to start the slot, and do a cleanup with a chisel.

And thats why I am on a woodworking forum, Thanks for the idea. However with the limited tools I have any advice on how I could rig this up to be cut with a circ saw or I suppose my dremel may be able to do that. There is a posability my dad has an appropriate router bit but I doubt he has anything that would cut deep enough. Suggestions?
