This has been done and posted before... http://www.jalopyjournal.com/forum/showthread.php?t=90824&highlight=reverse+your+own+spring+eyes But we thought we'd give it a shot. In the words of Flt-Blk... "Mark the original arc on the floor with pocket chalk then draw marks across the spring every 2-3" for reference We brought the press up to a touch then I think 6 pumps then move over 2" and repeat." Be sure you use pocket chalk and not that school stick chalk stuff, or this definitely wont work at all. We made our marks at 2" and made a total of 4 passes through the press... Start... In the press... After one pass... Pass number 2, pretty much flat... On the third and fourth passes, instead of pressing the spring on the mark, we went between the marks so as to keep the curve constant and not "lumpy." Done...we arched it slightly over what it was before to account for spring sag, whether it was worth it or not. The top is a stock spring, in the middle is a reversed leaf that was purchased somewhere, and on the bottom is the one we did. So, I would confidently say that anyone with a hydraulic press can do this on their own. No need to spend the money at a spring shop. Have fun!
