Draw!!
I bought a new file today so I'd be well-prepared to draw file my barrel. It's a file labelled as "single-cut" "medium finish" "metal removal" - aka a "mill file".
There are any number of excellent videos on draw filing. The best Kibler video is NOT in the SMR playlist on YouTube, it's actually in the Colonial rife playlist. That's an excellent video on draw filing.
To help me make sure my flat is actually flat, I mount it with reference to a bubble level:

These are some of the mill marks I want to make disappear:

Using the techniques outlined in the videos, they do disappear:

... leaving these curious metal shavings:

... which are proof of material being filed off.
I find it's helpful to put some marks along the flat to be filed:

... so I know if I'm filing flat or not.
Oops, not:

... so ... adjust hold pressure!!
Actually, this process is pretty easy and simple. Hard for even me to screw up. Nothing any first-timer should be intimidated by. Just have a sharp file and use good techniques as shown in the videos. Five minutes per flat may be a little optimistic, but not by much.
My only problem arose when I tried to bevel the muzzle, as Kibler does in his video, and as I've seen on some completed rifles. I found it was very, very difficult to file eight bevels of equal angle and equal depth, and eventually gave up and sort of rounded it off as best I could:

Not very happy with that, so I'd recommend to other first-timers to just leave the muzzle flat. It already looks just fine that way.
Meanwhile, any good ideas on how to remedy that / disguise that / just leave it alone are welcomed. But I just had to leave you guys with at least one little thing to jump on, no?
