Trumbly 38 mast This shows strips being glued to a mast member, held down with lead drafting ducks until the glue dries. The mast shown here does not seem to be part of the same mast as shown in the following photos. I believe that this was the mast for the Trumbly-38. Before the four quarters of the mast are assembled, strips must be glued to two of them to hold the members in place. The mast is only glued; no metal fastenings are used. Note that the mast tapers and is raked aftward toward the top. The wood used in this mast was clear, vertical-grain, air-dried Sitka spruce, which is strong but light. Solid spacers are added at the ends of the mast and one or two in the middle span. Solid spacer between ends. Glue being applied before addition of the fourth side. Note that electrical wires for a mast light have been added, as well as crumpled aluminum foil. The function of the foil may be to make the mast more visible to radar, though I am not sure about this. Clamping the glued mast. Clamped mast. Clamped mast. After clamping, the mast is wedged to ensure tight seams. Mast clamped and wedged. Prev. Next>
