I was looking at another thread discussing the 800 lb gorrilla that install's the Colt wedge's at the Pietta factory. The trick to initial removal, and removal and replacement there after is this......wrap your hammer head in rawhide !!!! For you "city slicker's" and creatively challenged folks like me finding the rawhide is not as hard as you think. Go to your grocery store and buy an unflavored rawhide dog chew toy !! You can cut it down with a hand saw to the right length while it's hard, then soak it totally immersed overnight in a pan of water and the next day it's plyable. Wrap the head of your hammer and tie it on securely. Wait at least a day for it to dry out completely....then feel free to smack away with no damage to the gun barrel or wedge. I make small pocket hammers for shooters with a wedge puller and screwdriver added to it that works perfectly for shooting both Colt's and long rifles.
