Valve spring pressure testing ??
This might sound mickey mouse, but...
Has anyone tried using a bathroom scale to test valve spring pressure?

As long as you know the free and compressed lengths (within a few thousandths of an inch, of course), you could do it.
And you trust the force data coming from the bathroom scale. At least the scale would yield better data than the bathroom mildew...
Get them checked the right way - with a "real" spring tester.

Easy.
You stack them all nice and neat, stand on them, take the reading, subtract your weight, then divide the result by 16, right?
Pressure in LBS and weight in LBS are 2 totally different things.
Kind of like how a 12 oz can of Mountain Dew doesn't weigh 12 oz.

I think if I was gonna do it, I'd center the spring on the scale and then use a big C-clamp to compress it the nessecary distance. And then read the lbs. it takes to compress it that much.
It sounds like it's not a method that's widely used
I'm running out of money, I'd rather buy parts than a spring tester.
