Frames update

Four new laminated frame ends have been built, and number 29 has been installed. (pictures coming) Each frame end is scarfed to the upper frame and the half-lapped scarf is secured with a bronze strap. A bronze flat head machine screw goes through the doubled layer of planking, the frame and the strap, secured by a bronze washer and a heavy nut. The end of the bolt is cut to size and punched to secure it.
The same scarfing procedure has been followed for the forward frames, numbers 13, 15, 17 and 19, except that the shape of these frame ends is straight enough so they can be shaped from ordinary planks, instead of multi-ply laminations.
In summary, the status is that all the floors from 24 to 12 are now fitted in place; those from 29 to 23 are fitted, but are being temporarily removed, one or two at a time, for ease in installing the frames. The odd frame ends are being installed first; 13, 15, 17, and 29 are done.
We are now held up because of a shortage of glue. Snediker recommended that the frame ends be laminated using Aerodux-500. Apparently, though, the only US supplier is in California and not too responsive. At any rate, we have used up T&S's supply and are awaiting more.
