Show t HANDICRAFT FOR BOYS AND GIRLS ! Br j- ,! A. NEELY HALL and DOROTHY PERKINS -. (Copyright, by A. Keely Hall.) A I'EDALMOBILE. Fig. 1 is about the most satisfactory pedalmobile that a boy can make. The front axle of the pedalmobile is straight (A, Fig. 2) ; the rear axle has two drops in it (B, Fig. 3). Fig. 4 shows a large detail of the rear axle. You will probably have to secure help at a plumbing shop or machine shop In preparing this. If you have the axle that belongs to the rear wheels, the bent portion of axle B Bhould be made of a length of gas pipe just large enough to admit the threaded ends of the wheel axle. These ends should then be cut off and riveted in the gas pipe ends as indicated indi-cated in Fig. 4. If you haven't been able to get this axle for the rear wheels, it will be cheapest to have the new one bent out of a piece of round iron, to the shape shown in Fig. 4, and then threaded on its ends for the axle nuts. The dimensions in Fig. 4 allow a space between the wheels of 22 inches. Fig. 5 shows the framework of the wagon bed. Make crosspieces C and D out of a 2 by 4 of the length &f the dimensioned portion of the rear axle B (Fig. 4); and cut horizontal piece E from a 2 by 4, and pieces F and G from a 2 by 2, each 4 feet 1' IJjglglll 1 1 IK I ' 1 ' long. Spike pieces B, F and G tc crosspieces C and D. Staple front axle A to an axle block H (Figs. 2 and 6), and pivot the blocl to the wagon bed with a carriag bolt (I, Fig.. 6) long enough to extend through a hole bored through pieces E, C and H (Figs. 2, 5 and 6). Blocl H must be deep enough so when th wheels are mounted they can turn en tirely under the wagon bed. Notcl the under edge as in Figs. 2 and 6, t( provide for the bolt head. Spiki blocks J, K and L to pieces E, F an G (Figs. 3 and 7), and staple rear axh B to them. The steering gear consists of i broom-handle post M (Fig. 5), stiicl at ., S a T I through a hole in piece E, with crosspiece N (Fig. 6) Bcrewed to th lower end, and a handlebar O (Fig. S screwed to the top. Uprights P an Q, and block R (Fig. 9) support th steering post. Bore a hole throug R. for tbe steering post. Screw a pal of screw-eyes Into axle block H, an another pair into crosspiece N. nea Ue ends (Fix. ). ani connect thr. with pieces of chain or rope. All that now reroali. to complet the pedalmobile Is tho Utachment ' the treadles S and T (Figs. 10 and 11 Make these of strips 1 Inch thick an 8 Inches wide, and hinge their fo vard ends to cro6Bpiece C with stra taJDtes (Figs. 11 and 12). FOR A HERBARIUM. You have all gathered wild flowers, but I wonder how many of you have a herbarium, or collection of varieties, varie-ties, with a record of both the common com-mon and botanical names, location where found, kind of soil, and other data. A 25-cent letter-file is better than a book to keep specimens in (Fig. 1), and the heavy, light yellow wrapping-paper wrapping-paper Used in butcher shops, cut up into sheets to fit the letter file, is good material to mount specimens on. In addition to the herbarium file, you must have a press. Don't use a yl - pile of books. Make yourself a regular regu-lar press, or ask brother or father to make one for you. Figs. 3 and 4 show' a practical press easy to construct, con-struct, and Fig. 5 a working diagram. Make base board A 12 inches wide and 1" Inches long, and nail the three cross strips B to the under side, one at each end and one in the center; and make the upper board C 12 inches square. Cut the hinge blocks D 6 inches long, three-fourths inch thick, and one and one-fourth inches wide, and bore a screw hole through each one-half inch from each end. By means of these blocks, hinge board C to A, being careful to locate all four blocks in exactly the same relative positions so they will work together. Mount a flatiron upon board C. This 1 can be done so it may be removed or . ironing day, by driving nails mtc board B at the sides of the flatiroi s . so the heads come down upon th I base, as shown in Fig. 3, and provid , tng.a nail to drop in a hole at thi l flat end, as shown in Fig. 6. The flat , iron can then be slipped between thi nails, endwise, and locked in placi ( by dropping the loose nail into thi j hole made for it. Double pieces o cardboard or tin, beneath the nal , heads, will hold the flatiron bette than the heads alone (Fig. 3). Tb flatiron not only provides weight fo pressing, but serves also as a handl 1 for operating tbe press. Nail bloc' i E (Fig. 5) to one end of board A as stop for board C to strike agains when the press is opened. Newspapers are good for placin specimens between for pressing, a they are sufficiently porous to absor Rap. A half-dozen or so sheets ar none too many to place beneath an above each specimen, a When ready to tranefer from th e drying papers to the herbarium sheet: ) daub glue here and there along th d under side of each specimen; then la e the specimens upon the sheets In s h natural positions as possible. Karro r strips of court-plaster lapped oer th d thick portions of stems will hnlp hoi r tdem securely. e Th name, place of finding, and ot! r data, may be written or printed I the comer of each sheet, as Indicate i In Fig. 2. Glue index tabs to th T. ddges of your sheets, In the same wa d that letter-file Indexes are put on, o r- which to letter the name of each g p nua, f) simplify the finding of spec mens. |
