The Steel Ball is Not So Easily Run Into the Hole as It Appears
To Start the Ink Flowing from a Drawing Pen
In order to keep the ink flowing readily from a drawing pen it must be kept clean and not allowed to stand with the ink in the nibs. A good plan is to have a small piece of velvet fastened to the drawing board or upon a small block, conveniently located where the pen may be drawn across it as in making a line. The tuft of the velvet will clean out the partly dried ink between the nibs.—Contributed by H. L. Woodward, Washington, D. C.
A Pencil-Sharpener Stick
Do not discard the sandpaper stick or pencil sharpener used by a draftsman just because all the abrasive sheets have been removed. Make use of it indefinitely by fitting a wedge in one edge, as shown in the illustration, to hold fresh sheets of sand or emery paper. The wedge should fit tightly so that the ends of the abrasive sheet, when wound around the block, will be held tightly. Worn sheets can thus be removed and new ones applied when necessary.—Contributed by Chas. J. La Prelle, Flushing, L. I.

Splice for Round Belts
Sash cords or round belts are easily spliced with a coil spring, and for belts this joint will run smooth and noiseless. The coil should be a close fit on the belt, and after turning one end halfway into the spring, the belt itself is twisted in the reverse direction as many times as there are coils remaining in the spring, before the other end is turned into it to meet the first.—Contributed by F. S. Cummings, Detroit, Michigan.
