A carpenter's tool expedites the cutting of lengthy boards into shorter segments of uniform length with a hand held power saw or the like. The angled tool has a linear board guide member that is abutted against a side of the board and a saw guide member which extends across the board and defines a surface along which the saw may be traveled. A stop member extends from the board guide member for abutment against the end of the board to to fix the length of the segments which are cut from the board, the position of the stop member along the board guide member preferably being adjustable. The hand of the operator which grasps the board guide member during a cutting operation is held at a location away from the saw by a thumb grip which extends between the operator's thumb and forefinger. The tool may also be provided with rulings for measuring distances in a building framework or the like that are to be spanned by the board segments.

This disclosure relates to a method and apparatus for manufacturing zinc coated steel tubing from zinc coated steel strip. The zinc lost by volatilization during welding of the seam is replaced in a two-stage metallizing process. In the first stage an aluminum alloy is spray atomized onto the tubing. The alloy contains from 0.45 to 0.95 weight percent iron, no more than 0.10 weight percent silicon, and the remainder aluminum with associated trace elements. Thereafter, in the second stage, zinc is spray atomized over the aluminum alloy-coated substrate.

Galvanized tube welded seam repair metallizing process

Metallic tubing is manufactured from galvanized steel strip by forming the strip into tubular shape, welding the edges together and replacing the zinc lost in welding by atomization metallizing the weld zone first with an aluminum alloy containing from more than about 0.30 to about 0.95 weight percent iron and then with zinc.
