Dress them clear and clean with a good 

 sharp plane. Now mark them as just 

 described. Make six brass clips, of No. 

 22 or 24 gage brass, as in Fig. 3. Also 

 make six as shown in Fig. 4. 



The bolt in the clip on the upright 

 should be tight enough to pull it into 

 the wood, and the wires on the trans- 

 verse stick should do the same so that 

 clips will not slip, but at the time 

 avoid bruising the wood more than 

 necessary. The twisted ends of wire 

 can then be turned in, and soldered. 

 The ends of each stick should then be 

 wrapped with several turns of wire, 

 keeping about % in. from the extreme 

 end. These wrappings should also be 

 soldered. The ends of the cross-stick 

 should then be notched for the bow- 

 string, as in Fig. 7. The bowstring 

 when applied should pull the cross- 

 stick as in Fig. 8. Always leave the 

 bowstring so it can be slipped. The 

 distance X should be about 6 ins. for a

Finally

 each stick,

on the upright. Then take a string, 

 strong enough to stand consider- 

 able pull, and pass around the frame 

 through the saw cuts. Make a slip- 

 knot where you join and hold in your 

 hands or fasten temporarily. Square 

 your frame by measuring this string 

 till corresponding parts on each side 

 are exactly equal, moving the sticks 

 in relation to each other till you get 

 the frame true. The cross-stick will 

 now be exactly at right angles to the 

 vertical, and the bowstring should 

 pass about 10 ins. behind it.

must cross exactly 18% of the length 

 from the top of the vertical stick. Be 

 exact if you want your kite to balance. 

 So, 72 ins. X 18% = 12.96 ins. = distance 

 from the top. Mark 13 ins. with a 

 pencil, and shade this slightly upward. 

 Now mark the exact center of the cross- 

 stick. 



The best material for making the sail 

 is known as silesia or cambric in the 

 dry goods stores. Any combination of 

 colors can be used if desired, but they 

 must join in a straight line up the keel. 

 Blue and yellow, white and red, green 

 and pink, etc., are all strong contrasts. 

 However, the colors seen most distinctly 

 at great heights are red and white, 

 black and white, orange and red, and 

 blue and white. Whatever the colors 

 you select, and plain ones are as good 

 as any, start by marking out on the 

 floor with chalk the four points of your 

 frame. Sew your cloth firmly on a 

 sewing machine, and lay it out as in 

 Fig. 9-
