Have you had the JOY of installing spiral locks? If not then I hate you so very much 
......
damn....seriously though I just got finished installing all of them in my pistons (3 hours!) and my fingers are in pain. Oh well....its one step closer to startup
.
Does anyone make a tool or have any tricks for doing this in the future?

Yep, as Kurt said, with a little practice, you can get them installed in well under an hour. But, your fingers will pay the price!

Spiro locks Chris,
First thing to do is stretch them out a bit so you get a gap between the coils. Makes it a lot easier to get them started with a small screwdriver as was mentioned.
I don't use spiro locks if round wire clips are available. The round wire clip requires a chamfered wrist pin. One advantage is they are easier to install and remove without harming the pistons. Biggest advantage is the wrist pin actually forces them tighter into their groove instead of trying to force them out.

Lock rings Chris,
You must specify round wire locks with your piston and pin order. I also order removal slots to make life easier if they need to be removed. In fact these slots can also be ordered for spiro locks.
Levi,
Spiro lock is a flat wound (two coils) pin retainer usually about .040" thick. You use two per side. The round wire clip is much better in my opinion. It is used on a lot of foreign engines (for years). Cosworth came out with them for racing back in the late seventies.

As stated, stretch them apart a bit (makes life much easier) in fact you can almost screw them in that way (small screwdriver helps out though).

We started using spiral locks on Harleys years ago, man I've always hated them. Then S&S started using teflon buttons that go on each side of your wrist pin. Those things are great, you just slide the wrist pin in the piston, put a teflon button on each side and put the whole thing in the bore, the bore size holds the buttons in & centers the pin in the piston. Why can't we use these in LS1's?

Interesting stuff. I have to install some very soon and the info is a big help!
I agree about the wire locks and teflon, I have been doing motorcycle engines for many years and these products are great. Only down side is when one goes flying into the crankcase of a 2 stroke, time to get out the case splitter!
