you just learned, that's all--don't give up! We all had to learn it. Luckily for you younger guys, the Internet holds all of your answers. Rich has a wonderful tech section that you should use as a guide next time:
When I came back from my hiatus of playing and bought my RG3120, this was like my bible. Now I don't even need to refer to it and have made a few of my own tweaks (I typically completely disassemble the guitar, remove pickups, etc).
Here's my opinion about the easiest way to get this trem going if you currently have no strings and the trem is currently out:
1. Back the spring claw almost all the way out. This allows you to attach the springs with no tension.
2. Screw in the locking studs with the locking screws backed way out.
3. With the guitar on its side, loosely place the trem in place, sort of holding it against the studs. Then lay the guitar on it's top. It does not really matter if the trem is completely against the studs yet, just make sure that it is mostly in place.
4. Attach the springs from the claw to the trem. These should go right on with no tension.
5. Install the spring lock on the trem to hold the springs in place.
6. Tilt the guitar back on on the side and while holding the trem against the studs with one hand, begin to screw the claw back in.
7. When you begin to get any sort of tension, insert the trem arm and push down. You can put the guitar back down on your workspace now. By holding down the trem arm, you will get tension in the springs and it will hold itself against the studs.
8. While still holding the trem arm down, place you soda caps of folded up bits of cardboard under the back of the trem and release tension on the bar. The caps or cardboard will hold everything in place.
9. Turn the guitar back on it's side and screw the spring claw most of the way back in. If you're using standard 9-42 strings in standard tuning, if you leave 7mm between the edge of the trem cavity and edge of the spring claw, you'll be really close to where it will eventually need to be.
10. Install the strings and begin to tighten them up. When you get a fair amount of tension, press the trem arm down and remove your soda caps/cardboard.
11. Continue to tune the guitar. Don't worry about getting it right on the money, just get something close to in tune. If you're tuning low to high, as you begin to get close, tune the low strings sharp and then tune the high strings to the correct pitch. When you go back to the low strings, you'll find that they've gone flat from where you originally tuned them.
12. When you're pretty close to in tune, check your trem angle by looking at the insert on the side. Adjust the claw in/out as necessary. If you're really close to the right angle, as little as 1/8 of a turn can make the difference between perfect and not correct.
13. As you're getting really close to the right trem angle, you will now want to tune the guitar perfectly each time.
14. That's it. I usually leave the strings locks loose for a while with new strings as they stretch out. One the tuning stabilizes, I'll lock them down. Play the hell out of it!
