Bruce, and others, Here is a description of what I am doing..I have 2 min diameter projects I am working on. First is the 98mm project. It will use a form of friction fit. The actual motor case will protrude…   Read more»

Actually similar to what Ed was explaining But a little different.Epoxy a Centering ring in place just down a little from top of the booster. Then using a piece of all thread cut to length for the specific motor size/length…   Read more»

You guys have the answers.

What Ed said…Warren

Ed, that’s a great idea. The rocket would be 3″/76mm, and I will be attaching the harness to the casing at the forward closure. Putting a bulkplate between the eyebolt and the closure would definitely hold that puppy in enough….   Read more»

How much room do you have? How about combining a threaded forward closure, an eyebolt, and a bulk plate epoxied in place at the forward end of the motor casing?Basically the retention is on the forward end of the motor….   Read more»

Ken, that might work. Good suggestion.

What about a slimline retainer. Since most likely you would be doing tip-to-tip FG on the fins, you could merge the transition from the retainer to the airframe with FG.Just a thought…

After I posted the question, I thought worst case, so the casing pops out the back. Everything is still attached, and the main would come out later on. At least, the rocket would be apart and less likely to lawn…   Read more»

Well, friction fit would work but internal clamping or an eyebolt in the forward closure attached to shock cord and/or bulk heads helps keep the worries down.

Got it. Friction fit.

You burned an H180 motor indoors?!!! My my… better that it was your garage than mine. Somewhere out on the web is a video of a guy doing a static test IN HIS GARAGE. Guess his test stand wasn’t so…   Read more»

Curious as to how large of launch towers we have access to. I would have no issues building one but if they exist already………Whats the largest rockets that can be flown from them.T-C has a 3 fin and a 4…   Read more»

We had a call-in of 30K arranged for MHM and Oktoberfest in 2006, but it didn’t get granted for 2007. We’re working on something similar this year, but don’t have any idea if it will happen. Joe is working on…   Read more»

The SwingSet actually sports a 19-foot rail at the moment. The rail that is currently on it is not standard 80/20 rail but it is compatible with the larger extreme buttons. I would like to convert it over to some…   Read more»

Without the needless drag of rail buttons, this is what the club needs for ANY serious altitude attempts at L-M (or N). This is great. Don’t we have a call-in 30k waiver, or used to?
