I was rootin’ around the basement yesterday when I came across some long forgotten toys. I retired from the engineering department of Modine Manufacturing. While I was there, every time we redesigned a machine or process, we would end up with perfectly good parts that were discarded or sold to employees at auction. The 8 foot slide was only 2 weeks old when then discarded it (they payed over $20,000 it and was just going to be thrown in the scrap metal bin to be melted down. My plan way back then was to build me a large CNC router/laser when I had some extra time. Ten years later I’m still looking for that spare time.
3 foot slide
4 - 4 foot slides (2 with steppers)
4 foot pneumatic slide.
Not pictured are 4 - 2 foot slides and 1 - 8 foot slide.
