Very cool Lloyd. I posted my latest design iteration of my igniter a few months back http://www.rocketmoonlighting.com/projects/pr56-igniter It looks similar in design to yours, but the body is conventionally machined. The fully dimensioned drawing is on the page for download. I've tested it with gox/propane, gox/kerosene, and n20/propane. I have an extra body ready to go if anyone would like to try it out RM On Friday, February 6, 2015, Lloyd Droppers <ldroppers@xxxxxxxxx> wrote: > Hi aRocket, you've been pretty quiet lately so I thought I would add > something to the mix.
