(Fig. 6) The square may be placed on face of building-board between the frames and checking from the center-line on building-board, adjust backbone until By CHARLES H. FARLEY (EDITOR’S NOTE: This is the fifth of a series of several articles on the subject by Mr. Farley, a nationally recognized authority.) 21. SETTING UP FRAMES ON BUILDING-BOARD (See Fig. 16) HECK up line of sheer, using light batten, and see that the inwale notches line up in a fair curve. Try the backbone on the frames when the latter are screwed in place. Trim and bevel mortises to allow the backbone to lie snug and fair in place, and so that the center-line of frames coincides with centerline of backbone. Do not fasten backbone to the frames yet. 22. BEVELLING FRAMES The outer edge of the frames may be perfectly bevelled with a batten about 34″ wide and two or three feet long, to which a strip of garnet-paper or garnet- cloth has been glued. The bevels can easily be made by bending the batten and moving up and down, or back and forth, on the edges of the frames and taking in two or three frames at a time. Mark a heavy pencil line right on the sharp (face) edge of each mould, as a guide to prevent accidental sanding away of the true moulded shape. 23. TRUEING UP KEEL-APPENDAGE and SKEG. (See Fig. 6) One of the most important opera- tions of all is to have the keel-append- age and the skeg absolutely plumb with the transverse axis of the hull, and even a slight variation of the keel-appendage or skeg from the vertical plane will f, | ii make the boat sail differently when changing from one tack to another, and to act erratically before the wind. Lining up on a flat surface as described in Paragraph 2 makes sure that the fin and skeg will be plumb with the backbone, but in mounting the latter on the frame-assembly, unless the mortises are absolutely horizontal, the backbone will thrown the fin and skeg ant_of the vertical nlane. the fin and skeg are perfectly plumb. If the fin is not shaped, and is still the same thickness as the backbone, the task is simplified. If, however, the fin has been cut to final shape, then its center-line should be the point to work to. A piece of thin metal, serving as an extension may be clamped on the square, and manipulated so a determined point just touches the center-line of the fin, and of course, working from the building-board center-line also. Reverse and check other side. If fin and skeg do not come true, pare off mortises until they do. A still better plan is to have the lead cast. then mount it in position before planking, and true it up as already described. In this way you will be certain that the keel-bolts will not throw the finished fin out of true.

They come in mighty handy for reference, Right now, I wish I could see more articles on scenery and layout work as I have reached that point on the construction of my own miniature railroad where I need such guidance. You fellow-modeleers may be interested in knowing, too, that I have partially completed a Great Northern elec- tric type locomotive, which was featured in the blueprint insert of MC in Febru- iets ary of 1940. I recently joined the Bridgeport (Conn.) Society of Model Engineers, and the fellows there seem to be quite pleased with the equipment on my HO road.

CRAFTSMAN MAGAZINE wishes to make it clear that it has no tangible connection with the proposed association. This publication desires merely to aid in the formation and operation of such an association in the hope that the promising hobby of tether-flying will become a more important factor in the near future. It seems to us that line-flying can and will do much toward preparing its enthusiasts for the handling of prototype airplanes during the coming few years—and there’s no doubt that airplane trans- portation will be THE transportation and address to show that you are interested in a national banding together of line-fliers for the good of the sport. Obviously, it would be useless for any national magazine to attempt coopera- tion in a project which failed to find interest on a national scale. So, if you’ll signify your interest by mailing us the coupon, or a facsimile, we’ll know whether enough of our readers are ready to forge ahead in this thing. However, we’re ready—and we believe you are. Watch Monet CrartsMAN MAGAZINE in September for further developments. (Continued from page 46) solve the problem. Of course, tether enthusiasts would be free and welcome 24. FASTENING BACKBONE TO As a suggestion, there could be different divisions of contest flying— such as spot landings, acrobats, speed, endurance and utility (utility flights would include weight-carrying, skywriting, aerial photography, etc.) Engine classes could remain the same as in current free-flying, and other rules now used with gas models could be utilized in tether work. Let us_ have your opinions. There would be no dues, no entry fee, no expense involved in the proposed association. The entire project would be held firmly together by your enthusiasm, willingness and co-operation. Mopet CRAFTSMAN MAGAZINE stands ready to offer prizes in the various classes in State and National competition as soon as standard regulations Cable Tracks FRAME ASSEMBLY Having made sure that the backbone fits into the mortises of the frames per- fectly, and is not twisted or warped, and having checked up plumbness of fin and skeg as described in Paragraph 23, we may proceed to fasten the backbone to the frames. Thin brass screws and waterproof glue should be used to hold backbone and frames together. Screws are put right through the backbone rabbet and into the frames, two screws to a frame. (Fig. 15). Where the stock adjacent to the rabbet is too thick to employ this method, then a small brass angle may be used, or blocks glued to backbone and frame. (Fig. 17). Mortising the bottoms (small ends) on frames into the backbone is not recommended, as it is apt to weaken the backbone. 25. INWALES (or CLAMPS) The inwales, often called clamps, may be of spruce, mahogany or hard pine.

Leave the upper face of the inwales project slightly ABOVE the line of sheer as marked on the frames, to allow for trimming to the proper line of the deck-camber. The inwales generally twist, and if they are put in without this allowance, there will not be enough stock to land the deck on properly. MYRAA PUBLISHES GREAT YEAR BOOK © LR Good Friend, C. H. Farley, sent us a copy of the Model Yacht Racing Association of America’s 1941 Year Book — we received it just before going to press. And we want to tell you yachtsmen that it’s a great book, full of information, including a racing qalendar and directory of officers and clubs, it’s attractively made up, with a red, white and blue cover, and there’s a fourpage center spread showing the burgees of MYRAA member clubs in full color. The book is illustrated throughout with photos of yachting activities and officers of the various clubs. Editing is the work of Mr. Farley. If the inwales tend to twist abruptly, where they butt into the stem or stern- piece, it is better to boil the ends of the inwales in a covered pan, borrowed from the kitchen, for an hour or so, and they will be found quite pliable. Bend slowly and carefully over some rounded object to the desired curve, then brad, clamp, or tie in place in the notches until dry, after which they may be fastened permanently, using brass screws and glue. Don’t for- get to countersink for screw-heads. Bevel off inwales on outer edge, so the planking will lie fair and snug across inwales and frames. nt. A complete line of model railroadin equipme form.
