One piece Nelson barrel progress

Progress on one piece Nelson (1),  Marvel (1) and My conversion (1) is slow but getting there. More work than I thought, lot of material needs to be removed from 2" diameter barrel blank! See attached photo for progress on the 3 barrels, photo is of Nelson barrel going to Adam.

I currently have the one piece barrel fitted in my Homemade slide. Used Lilja Match chambering reamer. I did plunk test, round dropped in to rim, round did not fall out when barrel turned upside/down. Swinging in hand with slight air Karate Chop fashion round dropped out. Cycled gun by hand, rounds chambered OK. Today I will test fire the gun. The 2 other barrels I'm making for an AA conversion and Adam's Nelson are near completion also, I do each operation on all three before setting-up for next. Being my conversion has a different slot for slide stop pin, the other 2 need that slot cut. My homemade version don't use a barrel mounted ejector so the slot for the ejectors needs to be cut as well as the extractor slot. One lathe is set-up to chamber the barrel using a 6 Jaw chuck with soft jaws, only chambered the Homemade version barrel so as to test the Lilja match chamber. I do have a Bentz reamer if the Lilja has issues but I'm thinking it will be better especially in the Lilja tight bore that is .215" X .2200". Being smaller bore I may need heavier recoil spring, Homemade versions uses 1911 recoil spring.
