The frames are built, the strongback is assembled, the chines are 80% done, and now I need a bunch of things to move forward.
First on the list is wood for the stem and transom. The plans call for white oak for the stem and mahogany for the transom. The stem is 2 1/4" wide, or 10/4 material....a look at the local hardwood vendors proves to be fruitless for anything that thick as a single piece, some guys have some 8/4 but that just won't do. So the only choice is to glue up two or three pieces to get what I need, the problem is that oak is not a good candidate for gluing with expoxy because of the high tannins levels. This leads to a long investigation into the merits of the various glues that are appropriate for below the water line useage. Turns out that the choices are limited to epoxy and resorcinol.
Resorcinol is the glue that is used to make marine grade plywood and what everyone complains about is the dark glue that it leaves and the fact that it is not a gap filling glue, in fact the surfaces need to be well-mated and clamped for the glue to do its stuff. On the positive side it can be used with oak and no one has any horror stories to tell about failing joints--even after 20 years.
Okay I'm in, resorcinol it is then. Here comes the spinning my wheels part...turns out that resorcinol is not easily available around here so now I'm back to square one. But a little more knowledgable on glue!
Decided to try out a local hardwood wholesaler called PJ White that I had heard will sell retail also. Turned out to be a good move, as I was pulling up to the yard I see a guy driving a fork lift with 8-10pcs of mahogany out to a contractor's truck. Beautiful looking boards all between 10 & 14" wide, 4/4 material each board 16' long. They carry two types of mahogany, african and honduras, african is about 1/2 the price of honduras. Ended up buying a single 11" wide plank, 16' long with nice figure (thought it will look nice if left bright on the stern of Willy) that I cut in two with a handsaw in the yard before loading it into my Volvo wagon.
The 4/4 material turned out to be closer to 5/4 so my plan is to plane a little off one side, glue them together with epoxy and use one of the 8' mahogany boards for the stem. I will have to find a use for the remainder of this board. But, the price was so good from PJ's that I can't go wrong--about 30% cheaper than the other local suppliers.
