Frames and Slides
We hold the philosophy that you must strive to be the best in the world at what you do. Our frames and slides are the foundation of a Cabot Gun. So we created our own unique tooling and fixtures. For us, it takes over 30 hours to build an extreme precision frame and slide.
The Ultimate Receiver
A Cabot Frame by Penn United Technologies involves array of state of the art technology is employed. Our machinists employ multiple axis CNC machines involving 85 separate operations. And that’s just the first step. Next we put our Wire EDM operators to work on aspects of the receiver.
Cabot Frames are then sent to our CNC Grinding Department. CNC Machining technology allows for accuracy in the 1,000’s of an inch. CNC Grinding technology takes precision to another level where tolerances are controlled to the millions of an inch. Our grinders, many of which are trained at our accredited school (LIGHT – The Carl Jones Learning Institute for the Growth of High Technology), and using our own CNC Grinders (Parker Majestic), grind our slides to exacting standards. The hand art of our frames is now involved. We employ Hand Metal Polishers, who work diligently under microscopes over hours of painstaking detail. Lastly, our bluing is done in our own bluing facility we constructed so we could control the process from beginning to end. Control freaks? Perhaps. Perfectionists, to be sure. Did we mention we use CMM machines accurate to 40 millionth of an inch to inspect and verify tolerances throughout the process and chamfer every edge of the gun?
Slides are more complex and time consuming to build than receivers. Each slide is built from 4140 billet. Decorative elements such as slide serrations, checkering and our Trinity stripes are not machined but rather performed using Sink EDM technology. Precision CNC Grinding using our in-house constructed Parker Majestic Grinders is employed to perfect tolerances and finish areas. All surface areas, exterior and interior are finished by our hand polishers. Markings are not rolled but rather engraved.
The art of the hand polish is at the heart of a Cabot Gun finish. Each Cabot Gun is finished with extensive hand polishing. Hand polishing is a skill passed down from father to son, master hand polisher to apprentice. Our hand polishers are dedicated to only that craft. Day in, day out. Varying degrees of polish take place with our Mr. Jones 1911 exhibiting the highest level of finish, followed by the CGI Classic, RangeMaster and GI Classic.
There’s no mystery why our finishes are what they are. The meticulous hand polishing allows for optimal surfaces to blue where flats are true flat, without broken edges, and rounded areas are true round. Of course, as control freaks we built our own bluing facility so we could control the process from beginning to end.
