(See Figure 2 - G for the dimensions and details of this piece) . Drill the holes for the pivot pin of the cross arm. This piece should work freely, but not have any excessive play. When completed, cement the part over the opening on the floor of the car. Figure 2-F shows the details and dimensions of the cross arm. A tin can is the best material for making this. Cut out two pieces, as shown in Figure 2-E . The tab on one end of each piece is used in assembly. Drill all holes and bend to the shape shown. Four small blocks of wood are used for the spacers. Two of them are 7/16" x Va" x V and the s" s" x Va" x ?i ". other two are V Assemble all of these parts, using cement and bending the tabs over on the ends. Be sure that the holes on the sides line up. A heavy stiff wire may be used as the base of the handle bars. This is pushed through the holes in the ends. "Radio spaghetti" tubing or heavy rubber insulation stripped off of heavy wire will make the actual handles. These may be held on with a touch of cement. Install the cross arm on the car and insert the pin through the holes, making sure that the cross arm has free movement up and down. The two pins used as bearings for the connecting rods, are next pushed into the holes on each side of the cross arm. The connecting rods should be made next. These transmit the up and down motion of the cross arms to the cranks of the wheel axles, thus moving the car. Place the car on its wheels. One axle crank must point straight up and the other straight down. This means that one set of wheels is a half revolution ahead of the other set. The cross arm must lie perfectly horizontal. Measure the distance between the center of the crank axle and the pin on the cross arm. Using stiff wire or a fine rod, bend up the two rods with the loop on each end. A bend i n the center of the rod is necessary, as shown in Figure 2-H. This is to clear the flow of the car when the crank of the wheels is in its outer most position. (Cranks point out to ward end of car) . A little experi mental work wiII be necessary as these parts may not fit or work perfectly at first, but with a little \'laUence and care you wi\\ be able to

arm, pins, and connecting rods may be removed and painted separately. A dull black paint is suggested. The name of the railroad might be added in white lettering on the side beams of the car. Steps and grab irons can be added for interesting detail.

thumb-tacked t o the underside o f the panel, with the tacks spaced between each hole. This holds the celluloid slides in place. A bulb from a car headlight, mounted in a long, flat tin reflector to cover all the holes in the bank, furnishes the necessary light. This arrangement eliminates indi vidual bulbs for each toggle. Neat code letters appear above each light hole on the panel. Small fiber blocks press spring contact points against a buss bar on either side to ground each circuit to the transformer. A Va" steel rod runs through all the fiber blocks to form the bearings. Figure L shows the details. My next venture is to perfect a turntable that is operated entirely by solenoids (five in all ) . For this I am using a 70 tooth ratchet wheel that ratchets completely around in either direction by double solnoid coils. This, also, was salvaged from the pin ball machine. It is a "bang up" idea, still in the experimental stage.
