Lancaster Porto Shrinker / Stretcher (1 body, 2 cartridges)

The original machine designed and made in Pennsylvania USA in 1939 and the only shrinker stretchers still made in the USA. All other machines that look like this are from the far East. Some are very well made like our STA105's but if you are using day in day ouit this is the boy.

US made sheet metal shrinker / stretcher. Used to shrink and stretch metal to create compound curves or for creating inside and outside angles in angled material.

All individual parts are available separately down to the last nut and bolt.

The body of the machine are made in cast iron and the jaws are hardened alloy steel. This combination, backed by over 70 years of tradition, make the Lancasters and lifelong tool. Each unit weighs just over 12lbs and comes ready assembled. Often copied but never equaled, these shrinker stretchers are the choice for any serious metal shaper.

All Lancaster shrinkers and stretchers are engraved "Lancaster" so you can tell you are buying the real deal that Charlie Beard designed for the Charlie Beard Tool Co. in 1939 that went on to become Lancaster Pump. See the history of the tool at the bottom of this listing.

A History of the Lancaster Porto Shrinker Stretcher

C-B Tool is located in the heartland of Lancaster County Pennsylvania. Along with the lush green rolling countryside and the Amish community, Lancaster has a prosperous variety of industrial concerns. One of these is C-B Tool Company.

C-B Tool began in 1939 as a jobbing machine shop and the manufacturer of a variety of automotive tools. It was started by an innovative and creative man by the name of Charlie Beard but after December 7th, 1941 the company focus changed.  C-B Tool quickly became involved in the war effort. Production during the war years was 24 hours a day, 365 days a year making equipment for the ships of our Navy.

After World War II ended the company went back to its original mission of machine work and tool making. The company made all kinds of tools, including: metal shrinker and stretchers, rivet cutters, a tool designed to help position tongue and groove boards, hole punches,  crimpers, cable splicing blocks, and more.  All that remains today is the rivet cutters and the shrinker and stretcher tools.

One of the first tools manufactured by C-B Tool Co. turned out to be the best. It was the shrinker and stretcher metal forming tool. It was a difficult tool for Charlie to perfect, but the final 1939 version is virtually the same tool today. The tool shrinks and stretches metal for inside and outside turns. No more cutting and welding. You work the metal to the perfect angle. It is an easy to use quality built tool that continues to grow in popularity.

Charlie Beard is long gone, but his legacy of premium workmanship in his shrinker and stretcher remains intact with the third generation of family members. His metal forming tools are now sold worldwide. His invention has helped those in auto restoration, the aircraft industry, and automotive body shops for nearly 70 years.  It’s a great tool that is literally ageless.
