If you're like me and don't have sponsors or deep pockets for high end shop tools and equipment, then you've probably shopped at Harbor Freight. I had purchased their shrinker stretcher with stand, and while the tool itself seems to work OK (I'm saying this not having used high end equipment to compare against) but one thing I quickly noticed was a poor design of the pivot point for the foot pedals. All they provided was a single bracket which won't last long before it starts tweaking and motion is lost due to the pedal moving in directions other than where it should go. To fix this I boxed the bracket with some scrap metal I had laying around and now it works much, much better.
Future plans may involve adding a thread or coupling nut so I can make the rods adjustable for tuning the shrinker/ stretcher tools so they will activate sooner.
