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.
Excuse my ignorance but I only have limited experiences with Aluminium and I'm no engineer, however both were negative. The first I used a 3000kg climbing Karabina on the font end of a inflatable to secure a mooring rope. After a couple of days it snapped like toffee and was perforated like a tea bag! This was a brand new item!
The second, whilst in the diving business I owned an ex-Royal Navy Fleet Tender. It was a 180 ton steel vessel, however it had an aluminium bridge bolted to the steel deck. A gasket was used to keep the steel and aluminium apart and it was bolted with stainless bolts.
My concern would be moisture in the system corroding the aluminium and reacting with the tube and dis-similar metals.
Just something to consider. Wouldn't steel or stainless be a better option?
