I want to add some decorative bands to some store bought thimbles. They are the smooth ones and are only 0.030" thick. I could see using a contoured tool and swaging the bands on but I am not sure how that would work as far as a bucking bar or form rod and removing the thimble after I stamp in the shape. I could file the shape but they are very thin. Should I start over and make pipes of thicker material?

Before making new ones, I would try filing in any decorations you want using needle files followed by sandpaper. All you probably need to do is strongly hint at it. Brass black will accent anything you do. If it doesn't work, you're not out anything except for your time

I made this set of pipes for my Kuntz build out of .032" thick sheet brass. the thumb nial on the entry pipe is swaged in, and the flats and grooves are filed. I won't say I had lots of brass to work with, but no problems arose. they fit a 5/16" rod.

That was just too easy after I got my head around it.

I concur with Taylor and Not English. I just posted these photos on the thread about the sub scale rifles but this brass tubing has a 0.032" wall and i machined the decorative bands on each end with a form tool in the lathe. The contour of the form is about 0.015" deep at its maximum and, as you can see, the contour on the brass is pronounced enough be distinct. 0.032" material is thick enough to file decorative features without making the final form too weak.

Scota4570,
I was posting at the same time you were...... :o In response to your forming of the rings.....Yes....or that !!!
Great job !

I believe making the bands is the easy part. How about showing forming the thumb nail and raising the extension on the entry pipe.

I too would like to see how it is really done. I tried on this one to do a thumbnail with a rounded punch and a lead block. I made a mess of it and flattened it back out.
I imagine if I had a thumbnail to copy I could the linotype metal to make the die off the original. Then make a make a punch by filing and spotting with inletting black.
IT seemed like too much work so I skipped it on this one.

This is probably well after the fact, but I wanted to add another $.02. Any flats you file in don't have to be totally flat. They only need to look flat. There can be quite a hump to your flats that will never be seen. No one will ever check with a straight edge to see if there flat.

Another approach from an original jaeger

I use a forming die and the cutouts are simple before the thimble is rolled
