Need: to formulate some sort of valve spring compressor. Pics of some homemade versions would be helpful. Or, alternatively, I may be able to borrow one from a fellow enthusiast at work, if he has one. I'm thinking if I fabricate one it will be along the lines of a big C-clamp with an "adapter shoe" made from brass or plastic (PVC?) tubing with access windows cut in to insert the spring retainer keepers. Hate to buy one for a one time use and I don't know anywhere I can rent one of the correct configuration/size. Granted, I haven't looked around anywhere either.
Here's some pics of the one I made for my 1100EX 16 valve head...
The plastic pipe is 3/4" - I epoxied a large flat washer on the top where the C-clamp swivel end sits. I then epoxied another small flat washer on the face of the swivel that fits inside the hole of the larger flat washer on the pipe end. That keeps the tool secured & centered on the C-clamp while you tighten it...
On the "spring cap" end of the pipe I beveled the ID so the spring cap would fit into the ID flush with the end of the pipe; then I mudded up the ID with some epoxy and pressed the "greased" spring cap into it to make a "mold" the spring cap fits into (the grease keeps the epoxy from sticking to the pipe). This kept the pipe from slipping off the spring cap (which it wants to do...).
You will also have to sand down the pipe OD a bit so it will fit better - it's a tight fit into some of the valve spring cavities.
The C-clamp has to have enough "throat" to reach the valve caps without rubbing against the side of the head, The clamp I used was from Home Depot and had 3.5" of throat, this was just enough.
The process of installing all the valves back into the head took me about 2 hrs, it's a real PITA to get those keepers in position on the valve stem so you can release the spring. My method was to apply a little dab of grease on the keeper and then pick it up with the end of a magnetized screw driver - once I'd gotten it into position I used the wooden end of a long q-tip to push it off the screw driver. Sounds hard, but once you get the hang of it it's not so bad - VERY time consuming.
Good luck!!
