Article from the American Bicyclist from December 1975. Article is devoted to repair tips, shorcuts and tools. Enjoy it :-).

To avoid collecting dust in the nozzle and cap when storing your paint gun, put about 2 inches of cleaning thinner in the cup; store the nozzle cap in it. Then place an ordinary kitchen-type plastic bag over the gun.
A paint gun is a precision instrument that justifies better care than many of them get. Care of the gun is primarily a matter of keeping it clean. Running clean thinner through it and wiping off spilled paint with a thinner-soaked rag will accomplish most of the cleaning job. If the air cap, or nozzle, gets plugged with dried paint, soak it in thinner.

Welding safety
Don't remove a cutting attachment from a combination welding-cutting torch and start welding with a small tip without readjusting the oxygen pressure. You may get by with this many times, but it could be the cause of a serious flash-back and fire or explosion in the welding hoses.
For cutting, the oxygen pressure is adjusted much higher, and many servicemen learn to adjust the flame on a small tip at this pressure and leave the gauge alone. This is fine, unless you get a flash-back and fire gets into the torch body. If there is an excess of pressure on the oxygen side, it can mix into the acetylene hose, and if fire gets back that far, the results can be disastrous.

Erasing rust spots on a bicycle's finish is easier and neater than sanding them away and can be done with a woodcovered eraser of the type used by typists. Chuck the wooden end into the chuck of an electric portable drill and whisk the rust particles away quickly. Chuck the eraser in so that only about 1/4-inch is sticking out. This gives the unit more strength to allow you to apply pressure.

Magnetic tool holder
Acro-Magnetics has introduced a magnetic tool-holder, designed to hold large and small tools, making them easily accessible. The Tool Magnet never loses its grasp, according to the company. Large wrenches, screw-drivers,hammers, pliers and other tools are said to be readily accommodated. Product is 24 inches long, with mounting holes 16 inches apart for easy installation.

Impact-tapping assist
With impact wrenches in common use, here is a helpful tip for tapping or cleaning threads. Use of a 1/4-inch SAE nut on a 1/4-inch tap; 5/16-inch or 5/16-tap, etc. Simply put the nut on the drive end of the tap and press on in a vise. The tap square will cut into the thread of the nut and should you put, too much torque on the tap, the nut will spin before the tap breaks. It's also handy because nuts use the same size socket as used for the bolt size being worked on.

Easier splicing
When doing repair work, should you find yourself with a severed wire whose ends are just too short to splice, make a fast repair by fitting a small piece of copper tubing over each bared end; crimp tubing tight, flow in some solder where possible as insurance against loosening from vibration, and wrap with electrical tape. If the standard wires are of very small gauge, snip off a piece of the brass tube from an old ball point pen to make the repair.

Insure pivot action
When you have two or more pieces of metal or iron to rivet together on a bicycle repair so that the joint will pivot, place a thin metal washer on the riveting block and let the rivet head rest on it. This permits the head to space itself from the joint so that there is only minimum friction between the parts.

Tighter drill chucks
Some hand-tightened chucks on hand drills and drill presses, which won't close tight enough to hold small drills, can be made to do so by using a flat hex nut. Unscrew the chuck and drop nut into the threaded hole in the chuck; then screw chuck back onto its spindle. The nut lengthens the threaded portion of the spindle, which forces the chuck jaws together more tightly.

Washing stainless steel
Before washing stainless steel parts on a bike or on one of its accessories, add baking soda to the wash water. The solution is non-abrasive and gives quick results.
