Segmenting a cartridge case
I know there are several knot tutorials but could you do one on the cartridge segment pens. I love the one for red, wht, and blue.
I have a tutorial posted at
http://content.penturners.org/articles/2009/6-Segment-Knot-Pen.pdf
This is how I do all my segmenting. For a cartridge case there are a few added steps:
I use new brass because the inside has to be clean.
Fill the case with JB Weld up to the neck of the case.
After the JB has set, drill with 1/4" bit.
Because of the taper in the case, you have to build-up the outside.
I have cast them in PR, but that takes too long to set for me, I want to do it NOW not the next day. Now I make a paste of powdered oatmeal and epoxy. It takes two or three applications to get a good thickness before I turn it round.
If you turn between centers as I do, be careful not to apply too much pressure or you will flare the bullet end of the case.
After turning round, treat is as any other round blank.
Hope this helps.
