Like the Sheridan did I use a brass tube as basic material. First I use a die to get the tube on the exact diameter I want. I developed a simple rifle cutter. So I am free to make my own twisted barrel in the right shape with the exact angle of twist. I know, other materials are more better and durable but if the barrel is wear away after thousands of shots (which I don't believe) I will just make another one in order to replace.

Your machine isn't too different in concept from what they used years ago: Very cool indeed. Guys that rifle their own barrels are pretty rare - tell us more. _________________ ¡Listo! ¡Apunte! ¡Fuego!   Posted: Tue Aug 21, 2012 1:52 am bluefalconholland New Member Joined: 19 Aug 2012 Posts: 7 Ok. Let’s start with the brass tube. The tube is from K&S #30. You can buy at a local model airplane shop. The tube has an oversized hole. To make the exact diameter I shrink the tube by pulling a die over it. You can shrink about 0,15mm each time. To get the die over the tube it is a must to take away some material (about 25mm) by using a lathe.   Posted: Tue Aug 21, 2012 3:45 am ZipSnipe Veteran Member Joined: 09 Mar 2012 Posts: 327 He teases us!! Are you using a machine to pull the die over the tube? _________________ You can have tomorrow, I'll take yesterday !!!   Posted: Tue Aug 21, 2012 5:36 am bluefalconholland New Member Joined: 19 Aug 2012 Posts: 7 Haha, no, I pull the die over the tube with the same rifling tool as shown on the next picture: At the begin of the tube i did solder a cone that will be fixed in the rifling tool.   Posted: Tue Aug 21, 2012 7:05 am Alstone Moderator & Site Supporter Joined: 01 Mar 2007 Posts: 4139 Location: Linconshire, ENGLAND Nice piece of kit BlueFalcon. Do you need a different outer tube for different twists and do you make your own rifling bullets.
