BUSCH PRECISION Aluminum Straight Edges are made to the same tolerances as Cast Iron Straight Edges (in five additional sizes). Starting with a cast aluminum alloy body, this series is specially treated for stress-relief and stability. After pre-machining, the top and bottom faces are fitted with cast iron wear plates which are then bonded to the aluminum body with super strong space-age adhesive. At less than half the weight of cast iron, these aluminum straight edges combine light weight convenience with the wear qualities of cast iron. Available in 10 sizes with precision ground or hand scraped finishes with faces parallel and straight within the tolerances indicated.

BUSCH PRECISION Dovetails Straight Edges are widely used for checking the alignment and scraping in the dovetail surfaces of machine tool ways and slides. Made from specially treated, close-grained castings, these tools are finish machined and hand scraped to flatness accuracies of 0.0001 per 12” or better. These “scraping masters” are normally supplied with a standard 45° angle. Other angles can be furnished at a nominal, added charge.
