Itís a joy.  Iron really sucks though.

I would rather file steel, but polish brass

Everyone has their likes\dislikes. I love the look of steel......not a big fan of brass. Then again, finishing up steel is, to me, much more work than brass.

I would rather use iron heat beat and repeat.

I am about to start on a couple of those and not looking forward to it.  Has anyone tried annealing the brass to help the job along?

I keep a separate set of files for brass.  Files previously used on steel don't cut brass very well for me.  But you probably know that.

Also I can get a lot of the brass work accomplished using scrapers.

As was said , I prefer to use scrapers first, and then follow with files. The files are used for brass only and cut extremely well. If I grab one of my files that I normally use for iron/steel , I can tell the difference immediately

 I'm trying a scraper to bring out the facets. Should it, the scraper have a burr on it or a square edge. I have found that on horn and wood I get a smoother finish with a square edge.

I use stones. Garret Wade made stones in a variety of shapes and grits for this kind of work. I have no idea how to get them. Maybe check with them first.
Remember what got us here.

I can't remember the reference, but one of the long rifle experts had made mention of examining originals and seeing signs of scrapers being used , especially on the inside surface of the trigger guard . The outside surface was filed and finished, but the inside still had the scraper marks

Woods Bob,

I was going to mention scrapers yesterday but was in a bit of a rush.

Polishing the inner curve of a trigger guard is a pain in the neck and rump.IF it is a common job or if it's not here is a way to do it.
Buy a Jacobs or that type of chuck and make an adapter to thread it to a bench grinder and then a set of expanding rubber wheels
with abrasive sleeves.Harbor Freight was my choice because there is a new one about 5 miles from me.This will NOT work on a rectangular trigger guard. It is also good on a crescent butt plate in brass,silver or steel.

Not a builder, but abrasive [impregnated] rubber wheels in a variety of shapes and grits are marketed by Cratex and I'm sure others.  Dentists use them, but they have their uses for some of our jobs as well.

I enjoy brass but the old Bronze sucked. Yes good sharp files are a must for me. I hope to never get cheap "brass" again. Ever.

I knock the flashing off with a File, then switch to 150 grit emery paper backed up with a flat file. After that I use progressively finer grit wet/dry paper.

Tim,  from an old post of mine........  (original here.......https://americanlongrifles.org/forum/index.php?topic=75691.msg751768#msg751768   )


After initial shaping with files, etc., I scrape most of the surface of brass and some steel parts.  I use the non sharpened edge of a utility blade.  This is a blade being used to scrape brass.  I use the same tool for brass, wood, and steel.  I stone the two 45 degree edges to a sharp 90 and use both sides of those.  Scraping a large butt plate takes about 30 minutes.  Scraping a whole stock to get out file, rasp, or carving tool marks takes about an hour...more if there is a lot of intricate carving to scrape around.  Then I use sandpaper where ever necessary or useful.

Here I am scraping a butt plate with the angled edge of a box cutter blade.  It takes off brass more rapidly and more smoothly than a file and leaves a finish that does not take too much more work with the abrasive paper or sticks.  I do the inside of the trigger guard bow like this as well.  If the part is investment cast, I can start right in with the scraper.  If it is sand cast, I usually hit all the surfaces with a file to knock down the roughness, and then start with the scraper. 

Wood comes off really fast and I have to be careful not to take too much.





As I said, I scrape some steel parts as well.  You just have to refresh the edge of the scraper much more often.
