The company I worked for -Rocketdyne - was the recipient of the German rocket stuff captured after the war. We all saw the old films where a worker would run by a V2 engine with a flaming broom to ignite the engine. Fortunately we used a somewhat more sophisticated system  which relied on puncturing a tube which held a fluid (hypergolic) which would burst into flame when it reached air.  You can imagine the tube was carried and installed  very carefully. 


 


In a more on-topic note, I completed the mounting for a tail-stock dial indicator.  I am using a chamber reamer to cut the chambers but I have been cautioned by Cutter to insure all the primer end of the cartridges are at the same distance or depth.  This obviously requires each counter bore to be the same distance depth-wise- as the others. This is a challenge for my ancient equipment,  bones, capability and talent.

Take your time with the chamber depths being equal. Better to sneak up on them a couple of thousands at a time. Take a break if you start to rush with them. The head space makes all the difference in the end with equal primer strikes or having some that are lite strikes which means misfires. If you do go too deep, it\'s still not the end of the world though, but you would have to thread those barrels in a little deeper and try again.
