I don't use the spring operated hold down, it works as intended, but I found it just got in the way and cut down on visibility of what I was trying to cut.
IIRC, they were solid cast iron with rubber feet so it would not damage the thin gauge brass/Stainless steel surfaces, it was one accurate shear, had adjustable back stop, even the blades cutting gap was adjustable.What was on the bottom of the hold down on the HACO? Just metal, or some hard rubber feet or?
The problem with the 3n1 is doing 3 very different processes in one machine. The original Polish or Czech machine it was cloned from was not very well received either. Every multipurpose machine I’ve ever seen was a jack of all trades and master of none.I like the idea of a thread related to all the mods on metal forming and shaping tools.
Where I worked years ago they had 10 foot long HACO shear with foot operated hydraulic hold down, it gave me the idea of using some type of pneumatic cylinder to replace the plate shear hold down but then I thought it would be an overkill for a 12" shear.
