Planing Rough-Grain Boards
The surface of a board having a grain that runs both ways is very hard to smooth with a plane. By sharpening the plane iron to a keen edge, then placing it in the plane with the cap reversed and set about 1/32 in. from the cutting edge, I find that with a light cut the plane will smooth regardless of the direction of the grain.—Contributed by William Rollins, Wichita, Kansas.
Braces for Aeroplane Frames
In making model aeroplanes or gliders the brace shown will serve the purpose admirably. The size and strength of the metal used will depend on where it is to be used. The metal is bent into the shape shown with the use of a vise. The manner of attaching the braces is clearly shown.—Contributed by Francis Chetlain, Chicago.
The Braces are Cut from Stake Iron or Sheet Metal According to the Size Machine being Built
A Puzzle Purse
The puzzle purse is made of four pieces of chamois, two of the pieces being merely flaps, one on each side at the upper edge. One of the pieces forming one side of the purse extends upward for about twice the height of the purse part. The part above the purse has a number of slits cut in it to make the width of each strip 1/8 in. These slits should be accurately cut in order that the purse may be opened easily. The other half is only the size of the purse proper. The upper edge of the latter piece and the flap on that side are stitched together to the flap on the opposite side, the threads of the stitches running between the strips of the long piece. These stitches are made on the line AB and around the edge.
