Big Machine, Big Improvements
An anecdote about this rebuild. This one is fiction. Our customer called to inquire about refurbishing their Pines #2. It was a well-worn machine with years of use, but the major components were still good.
Our team performed a comprehensive tube bender evaluation, and the refurbishment included a new Comptrol Controller, Refurbished Stationary and Swing Arm, New Hydraulic and Electrical components throughout, and a thorough clean and paint job to give this machine a new lease on life.

“The greatest improvement on this machine is the linear rail and pressure die holder with the outboard support because I can move it in and out with one hand.”
