NeighborJ Posted November 2, 2018 Share Posted November 2, 2018 I've been making and testing these things recently. Its taken losts of modifications to get it working reliably but it seems worth it.https://youtu.be/oRhBPhcSmY4 1 Link to comment Share on other sites More sharing options...
dagabu Posted November 3, 2018 Share Posted November 3, 2018 "F" Bomb, I like that! Tangential and offset? Is that the middle of the fuel grain, top or bottom? Empty tube below or clay filled? Link to comment Share on other sites More sharing options...
NeighborJ Posted November 3, 2018 Author Share Posted November 3, 2018 HI Dave, yeah it is basically an upside down Z-bomb with the drill guide flipped 180°. The nozzle forming rammer required modification to allow enough clearance for the drill bits. Here's some rough blueprints of the drill guide and rammer. The guide allows for 3 different vent sizes for various fuel options. Link to comment Share on other sites More sharing options...
