Valve spring compressor......what's everyone use?

-
Yep I may be swapping springs as well. Piston at tdc and rope will work to help keep valve up. PITA cut should work.
I'm looking for one also so I'm following this! I been thinking about making one. I love making my own tools for me it's part of the fun of the hobby iv made about 3/4 of my gunsmithing tools including an action wrench, barrel vice, recoil pad fixture, scope mount jigs. Alot of other jigs also. So I'm considering making one. I do have a stupid question about changing them with the heads on what keeps the valve from just falling inside the cylinder. Doesn't seem like a very safe way of doing it. I guess you would have to do them one at a time and rotate the engine around to let the piston up on the one your working on? I'm thinking of making or buying a clamp type.

One cylinder at a time. Rotate cylinder until piston is before top center and feed a long piece of rope into the spark plug hole, then rotate it more toward top center until it won't move, replace springs.

I went to O’reilly’s and borrowed their spring puller. Replaced all my springs while on the car. Took me a couple hours but it’s done. Made my first u tube video so don’t judge, but it shows the process. Right, wrong, or indifferent. Check it out.

Putting each cylinder at TDC works but it still leaves a little room for the valve to drop a little and makes it a pain in the butt.
As mentioned, start the cylinder up to TDC then feed about 5 feet of 1/4 nylon rope into the cylinder.
Then bring the piston on up until the rope is compressed against the valves and they don't drop at all.
Some use air in the cylinder, but I think that way is more trouble than it's worth unless you have all the stuff to do it already.
The rope is more positive and reliable in my own opinion.
 
I just made one up today using an old KB TOOLS piece, and a giant C Clamp. It works Great! Easy to use.

Had to add a short stud and nut to the end of C Clamp, to keep the spring pusher from sliding off the end of the C Clamp under high spring pressures. If it slips off, it will launch the retainer 30 to 40 feet across the garage. (Trust me on this). And could also damage your fingers.
