So for about the last 24 months, I've had her on a serious diet. Now I am happy to
report that she lost nearly 13 ounces and is feeling so much better. And let me
say one thing, when I pick her up with one hand now she is light as a feather.
Well, almost a feather.
Things I have done so far:
OEM main tube was lightened by me.
Barrel is OEM and trimmed down by me.
Main tube plug is made of Delrin by me.
Gas cap is aluminum, comes from HPA and bored out by me.
Hammer is made from Delrin by me with a modified 1701P striker.
Valve is an aluminum Disco rear end with a brass Pro-Top by Anthony.
Trigger grip frame is aluminum by Bluefork Design and then hogged out by Gregg.
Front barrel band is aluminum, made by Anthony, drilled by Rich and milled by me.
Acetal is a hard seal material so it's not forgiving of eccentricity. Nothing's to say
that either the valve seat or seal are perfectly concentric. It's common practice to
apply some lapping paste and spin the seal on the seat (e.g. with drill).
To make your own lapping paste, scrape some of that 1200 grit off with a blade and mix
with cutting oil or other.
