In general all fastenings are to be bronze wood screws or bolts and are to be of ap­proved sizes or as shown where required.

Wood Keel, Sternpost, Stem and Deadwood

The keel, sternpost, stem and deadwood fore and aft are to be of white oak, sided as required, to provide proper back rabbet for the planking and molded as shown on Lines and Offsets, Dwg. No. S-610-1. All faying surfaces are to be painted with thick white lead and oil paint immediately be­fore bolting together. In addition all parts after being set up shall be given two coats of linseed oil to prevent undue drying out or checking. Soft pine stop-waters, ⅝ in. dia., are to be carefully fitted at all necessary points as shown, which is the intersection of the back rabbet and seam. Entire assembly to be well smoothed and then well coated with Cuprinol or equal wood preservative.

Outside Ballast

The outside ballast is to be in the form of single lead casting weighing approxi­mately 1,600 lbs., fastened as shown to the wood floors and keel with 9/16-in. dia. Tobin bronze bolts. The finished outside lead casting is to be checked for weight and before bolting together a felt pad soaked in thick lead paint is to be placed between the lead and wood just before bolting up. Also about 200 pounds of lead ballast in 15 or 20 pound pigs is to be provided for trimming purposes.

Frames

The frames are to be white oak, sided and molded ⅞-in. selecled stock, steam bent and spaced 7 in. centers. The heels of the frames are to be boxed and fastened to the backbone. They shall also be fastened to the floor timbers with at least three 3/16 in. dia. bz. bolts. Where severe bends occur as aft in the vicinity of the deadwood and it becomes impractical to use a solid frame, the frame may be split in a fore and aft direction from the bottom of the frame to just beyond the point of extreme bend. In such cases the plank fastenings are to ex­tend through the outer member well into the inner member, drawing the two tightly together.

Floors

The floors are to be white oak, molded as shown or to have a minimum length of 7 in. measured along the center of the frame, whichever is the larger.
