Cool! Make the rocker shaft hole an open hook and use an old shaft to do them all at once.
 
Had to make one today as well, my old one didn't like the mechanical roller springs I'm installing.

I like yours better than mine the problem I have with mine is the gap is to small and I cant fit my fingers in it to put the retainers back on I'm gonna modify it to work eventually but I really like your idea better I may scrap mine and try yours lol

I chose a c-clamp instead of the f-clamp for a couple reasons. The first is that all my f-clamps are too expensive to sacrifice. The other is that I like the threaded rod to capture progress, as opposed to the friction/pressure that the f-clamps use.

Whatever works though, right?? Anything is better than those cheap spring compressors that fly off with the slightest bit of pressure.

I thought about this design but I wanted something to replace valve springs with the heads on. I have to run a lighter spring during break in then change them after I dont want to pop the heads off just to change springs

That’s a great point that I hadn’t thought of. I made the tool out of necessity during a complete rebuild, so the heads were already off. Looks like I’ll be following your design in the future if the opportunity presents itself!

I got to do some modifications to mine when I get the chance i have a million projects at once going lol
 
I had to modify mine a little to center the pressure closer to the center of the retainer. Actually it was kind of a lesson on rocker arm geometry

Yea I gotta do the same on mine I'm gonna change the angle of the arms a little when the are fully depressed it holes the retainer at an extreme angle
 
Not home made, I forget where I pick this up from but I did notice it at Mancini racing. A little pricey if seldom used. Not a problem in this house... LOL

I like it a lot. It works very well. You just have to keep the tool properly placed on the retainer and take note while you compress the spring. The spring /retainer does t always go directly straight down. It can catch the valve tip or the side of the valves little rough if your not careful. Not that I damaged anything yet, but it could if you went gorilla and not looked. I recommend this item if your not going to make your own. There are available for big and small blocks.
