The Estes Mean Machine(TM) kit was one I remember wanting, but not being able to afford the first time in this hobby. So now, as a B.A.R., I can have it easily. (Also, the kit cover picture is priceless.) 

I decided to high-power it by adapting it for 29mm motors so its name is now the "Meaner Machine." Adding a 29mm motor mount, fiberglassed tubes and fins and altimeter dual deployment is the final irony. $23 for the kit, $200 for the accessories. Actually, I ended up buying two Mean  Machine kits (because I needed more couplers) so perhaps it should be the "Mean Machine²." (Or "Mean² Machine?"). 

The kit still has a priceless cover picture. Dig that kid with the Farrah Fawcett layered hairdo and the trippy "Model Rocketry is Fun" T-shirt! This is probably the same cover it had when I was a child. (Yes, I'm a Gen-Xer, not a boomer.) 

I used the Estes body tubes and nose cone, but not much else. I wanted to keep the overall dimensions the same while making the rocket use dual-deployment recovery and an altimeter (just to complete the irony). Because I was using a 29mm motor mount and wanted to use through-the-wall fin mounting, I re-cut the fins from 1/16" plywood and fiberglassed them (double 2oz. wrap plus .56oz. veil). The three body tube sections were built using the Estes tubing and then fiberglassed as well (also double 2oz. wrap plus .56oz. veil). I noticed later that the Estes tubing has almost the same O.D. as LOC/Precision 38mm motor mount tubing, so that would have been a stronger replacement. But, I had to use some parts from the kit! 

The couplers from the Estes kit were pretty weak looking: thin cardboard and only 1 1/2" long. So, I lengthened and strengthened the couplers by putting two end-to-end (requiring the second kit) and fiberglassing them inside (strips of 4oz. cloth). Now we've got a high-power rocket! 

I really like the look of this rocket. I managed to keep the appearance of the original Estes rocket by using the same overall body tube length, nose cone and same size fins. Of course, the entire rocket is built with epoxy instead of white glue. The airframe is cut into three parts to accomodate the altimeter section in the middle. Two of the original body tubes make the tail section, slightly less than one make makes the altimeter bay section and slightly more than ones makes up the front section. The end result is that the rocket maintains the same finished dimensions as the original kit. 

Aside from the body tubes and nose cone, the rocket is scratchbuilt.

The altimeter needs to fit inside the small tubing. I used a Transolve P2 since it's narrow and this rocket, of all of them, can accomodate the extra length. This involved even more couplers and a custom altimeter plate and end bulkheads to fit in them.

I finished the rocket with the kit specified paint scheme. The only modification I made was to remove the Estes logo from the rocket name. I probably should have kept it, but I thought it was a bit tacky for them to put their name on my rocket so it went.
