Abstract: MASKING COMPOSITIONS FOR CHEMICAL MILLING AND METHOD FOR APPLYING THE SAME                 ABSTRACT A method of coating a metal part with a peelable mask which is resistant to attack by the strong acid and strong base etchants used in chemical milling is disclosed in which the metal part is surfaced with a layer of polyvalent metal salt, such as calcium nitrate, and then immersed in a high solids content anionic emulsion of coalescent rubbery particles heavily pigmented to contain at least about 45% total solids content and at least 20% pigment, the pigment to binder ratio being from 0.75:1 to 1:0.57.  The salt-surfaced metal part is held in the anionic emulsion until the desired coating thickness has been anodically deposited thereon, and then the coated part is removed and baked to complete the formation of the mask.  The rubbery particles are preferably constituted by an anionic polychloroprene homopolymer emulsion which is used in admixture with a curing Anita for the homopolymer, like zinc oxide, and a polyvinylidene chloride latex.  Sodium bichromate is included with the polyvalent metal salt to enhance corrosion resistance, and a silicone release agent is included to control adhesion to the metal substrate.

Abstract: Abstract of the Disclosure A brake lathe for drum and disc rotor brakes for grinding the inside cylindrical surface of a brake drum and machining the opposite parallel surfaces of a disc rotor.  The lathe includes rotating spindle output shaft extending along an axis of the lathe housing.  The spindle is driven by a motor which translates an endless belt over a V-belt pulley.  A pair of cog belts respectively connect an intermediate pulley to the V-belt pulley and a taper lock bushing mounted on the spindle shaft. This arrangement reduces the motor speed to the desired spindle output speed and eliminates the need for an idler shaft.  A first cross-feed slide is mounted in a direction transverse to the axis of the brake housing on a first side thereof for advancing the inboard and outboard cutters toward and away from the opposite parallel surfaces of a disc rotor concentrically mounted on the output shaft.  A second cross-feed slide is mounted adjacent the axis of the housing and parallel thereto on the opposite side of the housing relative to the first slide and is adjustable from the first side of the housing.  The second slide advances its cutter against the inside surface of the brake drum visible from the first side of the housing   Accordingly, an operator need not lean over the axis of the housing when adjusting the depth of cut of the brake drum.
