Carl Quick's LiteWieght 2240

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.

Two steps forward...

one step back.

Well, in my amazing cough prowess as an uh ahem "expert" machinist, with one fell plunge of the quill on my El Cheapo Taiwanese Bridgeport clone mill, I afforded myself the opportunity to refine, redesign, and remake the breech on the PCP project.

I found that the aluminum pedestal in the auto loader was garfing up the pellets as well as causing excessive friction. I made an insert to hold the cylinder out of Delrin. The tolerances are much better this time around so in the end the extra work will pay off. There's still quite a bit of work left to do on the breech.

Oh, and the reason there is a 1/2" piece bolted to the back of the breech? I had a moment of subconscious spontaneous creative brilliance that bored the barrel hole a 1/2" too deep. A long breech will look cool on this rifle anyway. DOH!

My hat's off to those in Crosman land and beyond that can take a block of metal, clamp it in a mill vise, and with a hand mill create a work of art. It's so much harder than it looks.

But all this practice is teaching me a great deal about machining. The next project will be that much nicer. Phil, I'm watchin' that big bore pumper. Ya got me thinkin'...
