I purchased a Mastermill 1-22 from HGR, Nice machine but as with most machinery there it has a minor problem. The quill spring is broken! I started contact just about everyone I found that make similar springs, one referred to another and so on but I found nothing. Looking in McMaster Carr I found the same thickness spring stock 2" wide. Mine is 1.875 wide. I managed to cut it to size with a carbide endmill, it was smooth and even, I was surprised on how well I was able to trim it! I measured the length, made an arbor and wrapped it. Looks very much like the original. Inserted it in the housing then in the mill. I have all the manuals having purchased the 3 on ebay. Removal and replacement is easy! BUT when I adjusted it to just about hold the quill at the top of the travel with nothing in the spindle the amount of force need to move the quill down is somewhat more that I am accustomed to. I have a Cincinnati Tool Master, the pressure needed to move the quill is constant, don't seem to increase or decrease. When I remove my hand the quill remains in place, don't move enough for the hand feed to engage.
My question is did I make the spring wrong or does the 1-22 spindle return like one on a drill press? The pressure needed is about the same as a drill press and quill returns like the ones on drill presses. Not much force to bring the quill down but constant increase is required, is that normal for this machine?
