After looking all over my local area for someone that had a spring tester I decided to man up and make my own. I was surprised hw many performance machine shops and big money pro engine builders didn't have one and after watching the old Rimacs bring in $400+ on ebay I built this.
I know it would work in a vise, drill press or arbor press but I wanted more control on the compression and a way to hold it there for precise measuring. It took some thinking to make it adjustable for more then one type of spring. I think I got it. My last mod is to design a saftey cage after having one pop out at 200+ psi and catch me in the finger before dancing around my garage.
It was something I needed since I picked up many assorted valve and clutch springs in a buy I made a while back with minimal notes and ID. If anyone needs springs tested let me know and I will do it for a reasonable cost. It is not so important on stock builds but when you get outside the box this can make ideas come to life without total guessing. I already found out a few things that were interesting. If you look at the spring in the vise now you can see it has 96 psi at installed hieght of 1.457 compared to 35 - 42 psi of a stock one. The clutch spring info will be handy too once I get into building my slipper clutch.
