Building a Minie Mag at the moment and have plans for a few other 38mm capable rockets, so I acquired their 38-29mm adapter. Didn't quite care for how the usage is described in their instructions.
So, in place of the cardboard thrust ring I made a 3/8" ply thrust ring for the 38mm tube. Realizing the stock z-clip holes then wouldn't work, I added some threaded inserts further outboard so the z-clips can hold onto the 38mm thrust ring. Then, the 29mm tube got a nice Estes threaded retainer that still clears the z-clips. This seems to keep the motor more forward than as designed and should be plenty secure. The supplied thrust ring is 1" long
Anyone done similar with these? I doubt this is an original idea.
