That should read dip a 3/16" hammer shank...--too early.

Dip a 3/16" and swab the hole lightly. You don't need that much. Don't work too far ahead. I swab two unisons at a time.

I have been curious about the use of PDF's. My question to those using PDF is, how do you use it, without making a mess of the plate and yourself? Not seeing this done, I can't picture to process.
