Joining the Two Pieces.
Take a thin metal sleeve—this is merely a hollow tube of aluminum or
brass open at each end—8 inches long, and slip it over either the
tongued or grooved end of one of the frame timbers. It is well to have
the sleeve fit
Splicing Beam With Metal Sleeve.
[Description: Black and white illustration: Three-part diagram of splicing
beam joined.]
Push the sleeve well back out of the way. Cover the tongue thoroughly with glue, and also put some on the inside of the groove. Use plenty of glue. Now press the tongue into the groove, and keep the ends firmly together until the glue is thoroughly dried. Rub off the joint lightly with sand-paper to remove any of the glue which may have oozed out, and slip the sleeve into place over the joint. Tack the sleeve in position with small copper tacks, and you will have an ideal splice.
The same operation is to be repeated on each of the four frame pieces. Two 20-foot pieces joined in this way will give a substantial frame, but when suitable timber of this kind can not be had, three pieces, each 6 feet 11 inches long, may be used. This would give 20 feet 9 inches, of which 8 inches will be taken up in the two joints, leaving the frame 20 feet 1 inch long.
