used at ordinary room temperature, as received from the manufacturer, thus eliminating special
equipment, precautions, and preparations required for efficient use of hide glues.
LEA POLISHING COMPOUND
Some of the compositions used with these wheels are abrasive powders, Lea Polishing Compound,
and, glue to bind the abrasive powder.
All polishing wheels, no matter what method of setup is used on them, should be broken up. This is done
by striking a blow to the face of the wheel with a round bar at a 45" angle to the side of the wheel. By
striking a blow every 1/2" completely around the periphery at this angle, and then by striking another
blow every inch at 90 degrees to the first blow, a diamond pattern will be formed, which is the ideal
pattern for good polishing.
Breaking up of a polishing wheel, after it has dried and just prior to its use, also serves to localize any
tendency the bonded abrasive might have to rip off if a sharp corner of the piece being worked is thrust
against it too quickly.
The cake lime, which comes molded in containers, is excellent for putting a high polish on rubber butt
plates, fore-end caps, plastics, and non-ferrous metals.
Emery paste is used as a lubricant and cutting agent on wheels coated with abrasive. Emery paste
comes in a molded paper container and is made in grit sizes from 90 to 180 inclusive.
Lea Compound, is one of the finest compounds that I have used. It is a greaseless composition that
comes in a round solid bar about 10" long and 2" in diameter, and enclosed in a hermetically sealed
metal foil container. In addition, although it comes in various grits and grades, the grade "C" (200 grit) is
best for all around polishing on guns and gun parts.
Where applied to a revolving wheel, the frictional heat causes the compound to melt at the point of
contact with the wheel and to transfer. It immediately sets up and dries on the wheel, forming a dry,
grease-free, abrasive-coated wheel. After a gun has been Lea-buffed, it need not be cleaned with a
