Rando Posted May 22, 2019 Share Posted May 22, 2019 Any reason for me to use gerb specific tooling for gerbs if I already have the same size rocket tooling? How different are they? I realize I'll have to use an appropriate formula for gerbs, and not rocket fuel. Link to comment Share on other sites More sharing options...
Arthur Posted May 22, 2019 Share Posted May 22, 2019 Gerb insides are a multitude of shapes. Some have a shallow core like a whistle rocket, some have a parallel core with no comp at the bottom. LOTS depends on whether you want 2m or 10m height with 1 second or 1 minute duration. Some light st the top some at the bottom. Link to comment Share on other sites More sharing options...
Rando Posted May 22, 2019 Author Share Posted May 22, 2019 With that in mind, there's no reason I can't make a few and see how they work, at any rate. Link to comment Share on other sites More sharing options...
