A Portable and Adjustable Holder for Storing Round Stock

IN shops or storerooms where rods, pipes and the like are kept, some kind of a rack or holder should be provided to keep them from rolling about under foot.

��Popular Science Monthly

���The uprights are adjustable to accommodate a large or small quantity of stock and can be moved from place to place

��Stationary racks serve the purpose well, but they cannot be changed when a dif- ferent location for the material is wanted. The holder shown has been used with success, and it was not expensive to make. The wood used was picked up about the shop and one of the men doing carpenter work put it together. One rack is required for each end of the stock.

Each standard is i8 in. long and 2 in. square, with two pieces, each lo in. long, 2 in. wide and i in. thick, fastened at right angles to the lower end as shown. The horizontal pieces are spaced for holes i in. apart, which are bored with a bit 7/16-in. in diameter. A ^-in. bolt about 6 in. long is used to hold the parts together.

If only a small number of rods are to be kept, the uprights may be pushed together, closing the space between them. When the stock is placed in the holders the weight keeps them firmly in position.

��Finishing Aluminum Surfaces on a Buzz-Planer

ALUMINUM is a metal that can be worked with rapid cutting machines, the only drawback being in holding the pieces so that they will stand the strain and resist the cutting stress without dis- tortion. The practical limit thus far at- tained for cutting speed is 150 ft., and a manufacturer of aeroplane engines has used a buzz- planer for surfacing the alum- inum oil pans that go under the engine crank-case. The walls of these cases were only }/s in. thick and were hard to hold in an ordinary fixture, so the buzz-planer was tried out with excellent results. While more cuts had to be taken, the speed with which each one was done made it possible to complete the sur- facing in less time than in the ordinary way.

��To Repair Nail -Hole Punctures in Rubber Tires Economically T is not necessary to paste a large patch on a small nail-hole puncture. Just as good results can be obtained in a much more economical way. Pick out the hole until there is a very clean perforation, then roughen with sandpaper. Apply the cement, allowing it to dry 25 or 30 minutes, and fill the hole with a small plug of tube- stock rolled up to fill the opening. Cure 5 minutes on the flat plate. The pressure will form the rubber plug into a sort of a rivet on the inside and the repair will hold just as well as a bulky patch.

��Turning Small Screws in Difficult Places with a Wood Screwdriver

TAKE a piece of peg wood, or the end of a wood penholder, or match, or similar strip of wood. Shape the end into a screwdriver-bit so that it will snugly fit the screw slot. Such an improvised screw- driver will hold the screw firmly at any angle and will drive it almost home, when the process can be completed and the screw set up with a metal driver.

��A Snowshoe Fastener Better Than Strings

^HE ordinary method of tying snowshoes may be improved upon by making a fastener like the one illus- trated. The toe-clip A is of light harness leather, with straps B for attaching it to the web of the snow- shoe. The buckles C are for the straps B and the strap D engages the buckle E. This toe-clip can be adjusted even with cold fingers, in a minute's time. — J. L. Bayley.
