Yes, that&#8217;s what I said.  The standard carrier is about 6&#8243; long, so this workpiece is short, and as always on such things it was too short to use a live center and still have room to work.<\/p>\n<p>There is a radius on the carrier that I cut by hand, since my lathe is an old fashioned human operated machine and not CNC.  The radius really isn&#8217;t hugely difficult, but it can be tricky.  I felt like I had cut it perfect on this one, and was feeling rather proud of my mad machining skillz.  <\/p>\n<p>One of the last operations was to cut the boss where the carrier goes in to the cartridge.  One slip, and I cut too deep.  The workpiece hung up on the cutting tool, and was pulled in to a chuck jaw and then slung out of the machine.  The result is as pictured.  Keep in mind the &#8220;hung up on cutting tool\/pulled in to chuck jaw\/slung from machine&#8221; sequence can be measured in milliseconds.  That is the para-carrier became a projectile long before being loaded in to an M203.  That sort of thing in a machine shop tends to get your attention.<\/p>\n<p>I keep these things &#8212; this one is a pencil holder &#8212; because I know that if I don&#8217;t have an epic fail every now and then, I&#8217;m not trying hard enough.<\/p>\n<p><img src=\"http:\/\/www.firmwarez.com\/wp-content\/uploads\/2012\/03\/60299_480079074202_670609202_6951119_1390446_n.jpg\" alt=\"\" \/><\/p>\n","protected":false},"excerpt":{"rendered":"<p>I was machining a custom short para-flare carrier for a 40mm grenade launcher.
