Well...Kind of weekend...
Started last weekend on grip to refinish it...had 4 coats of tung oil on by Wednesday evening...
After buying, I identified what i had considered needed repaired or wanted to repair.

Barrel lug to Frame Gap (very noticeable gap when held up to light)

Short Arbor (approx .021 upon initial inspection)

Hammer to nipple spacing(hammer needs at least .015 filed down for proper clearance)

Hammer Safety notch filled with epoxy

Hammer roller for main spring seized up (seized from factory, cut out for wheel wasn't deep enough, had to use dremel cutting discs, 2 together for thickness, then cut a deeper area for roller to spin freely)

Smooth out the spent cap removal port

Filed and smoothed out all internals

Lightened up bolt spring a little

After repairing barrel lug to frame mating surface, I then made spacers to repair short Arbor. I then had to file forcing cone to end up with a good cylinder gap for this brasser (.005)

Replaced nipples with treso ampco nipples

New Wedge

A little Oxpho blue here and there

2 layers of Minwax wood wax on grips

I figured 8 hrs all together including grip refinish, everything feels real good now. I originally bought this ASM 1860 to cut down (belly gun) but after getting it i realized the barrel was 8 inches and had no manufactor or Black powder markings on the sides and looked to good to cut down.

What is the purpose of filling the hammer safety notch? I've had a Centenial 1860 for 54 years and wondered why they even put it there since the cylinder didn't have any real safety pins just a nub where they went.

Going back to a THR discussion in 2012, filling the notch in the hammer for the safety pins on the cylinder was recommended because fired caps occasionally got stuck in the notch.

Considering a lot of cap'n'ball cylinders don't have pins, it sounds reasonable to fill in the notch.
