The queer handles ha\-c carved grooves that slip into the end of the side-[)ieces on the order of the old- fashioned wooden bedsteads. The wooden standards are "square pegs in square holes," and serve as rests for the barrow. They have an extension running up on the inside of the barrow, where they are bolted in place. The wood selected for the front wheel should be at least lyi in. thick in order to afford stahilii\-. The sides are sawed in such a shape that the iron rod from the wheel passes through the center of his clownship's palm where it is secured with

��Constructing a Sidecar for a Bicycle or Motorcycle

THE accompanying illustration shows the construction of a simple sidecar for a bicycle, which may be enlarged for motorcycle use. The frame of the side- car should be strong, light and well made. Bass- wood will be found very dur- able for a light sidecar for a bicycle. The joints at the corners arc lap- ped with a small bolt run through them to hold the parts tighth- to- gether as at .1 . The frame is rect- angular, 30 in. long and 16 in. w i d e, made o f pieces i^:^ in. wi(h- and % in. thick. The sides of the body are built up of }4-in. boards fastened vertical- ly to the frame, and a side rail

��placed 15 in. above the frame, which is used for supporting the seat and also as a means of attachment for band-iron braces to the bicycle. Screws should be used throughout for fasten- ing the boards to the frame and rails. First fasten them to the side rails, then draw the curved line at the toj) and cut both sides out at the same time after clamping them together. Before fast- ening them permanently to the frame, lay a floor of ^4- in. boards. A single board 16 in. long placed on the side rails makes the seat. The back is put on in the same way as the sides.

The side wheel, which is an ordinary front bicycle wheel, is attached to the body of the side- car with braces of band-iron i^-g in. wide and 3 16 in. thick, the forward one being fastened over the side rail and the other to the upper rear part of the body. The inside end of the hub-axle is supported by a piece of the same band-iron shaped as shown at B and bolted over the side boards to the frame back of it.

The same sized band-iron is used for attaching the sidecar to the bi- c\cle, one piece connecting the body to the bi- cycle frame be- tween the large sprocket and the small one, and the other between the side rail of the b(3dy, through the boards to the tube connecting the seat and the rear- wheel hub. This is shown in C and D. The bars of tlic last attach- ment must be twisted slightK', as the drawing shows, to allow forthe slant of the bicNcle tube.
