Rh shaped as shown in Fig. 221. Steam the plane thoroly over the teakettle and place it under pressure until dry and it will remain so bent. The plane is also tilted up a little by means of a small wedge.

The spine is made of spruce and is ″×″×12″. The large plane has about ″ camber and is bent as shown in Fig. 222. Lay a strip as thick as the desired camber on a board that you can nail brads into. Steam the veneer for the plane and lay in the ″ strip in this case about one-third the distance back from the front edge, bend down until the edge touches the board underneath the strip and drive brads in slanting so as to hold it down. The brads can be bent down a little after they are driven in. By using brads on both sides the veneer can be held down until dry. The outline can be cut away before or after the bending. The decoration of course is not essential, but it is interesting to beautify it a little. The anchor block for the propeller shaft is of wood ″×1″×1″ and is glued and nailed with brads to the rear end of the spine. A piece of tin ″ wide is bent about the top of the anchor block, f, Fig. 223. The hole in the wood should be larger than the propeller shaft while the hole in the tin should make a good fit. In this way the bearing is on the tin instead of the wood, and reduces the friction to a minimum. After the tin is on, the block should be wound with linen thread and coated with glue or shellac.

The propeller shaft is made from a bicycle spoke, Fig. 223; two of these can be purchased for a nickel. The long nut,
