[R-390] Any help for a beginner?

[Bill Hawkins]

Darn, I forgot to mention springs.

If you have ever opened some mechanical device and had a spring
fly out, maybe taking other bits with it, then you know what I'm
gonna say.

One of the best reasons to practice is that the R-390A is full of
springs - on gears and Oldham couplers, slug racks and others.
Use the drawings to find those springs in the set, make notes
about how they are installed and what is attached to them. Do this
before you pick up the pliers.

If you don't, there is one more R-390A that will not go back together
properly.
