I have one of these somewhere. I'll dig it out and post a photo.

See below. While I was digging, I found some old B3-6 motors (precursor to the B14's). The B4-0P I bought from Phred at NARAM 50. Has anyone heard from him lately? S.

Wow, that just popped up an old, old memory of when Estes switched from pounds to Newtons on the engine designation. Not sure but it was right after I started so around 1967. I recall my old chemistry set from that era - lots of neat chemicals, I remember making some of my own recovery wadding (there were instructions in the chemistry set for making the compound that made the tissue fire resistant) but quickly decided it was more trouble than it was worth. My mom's only worry was that I start a fire with the alcohol burner that was part of the set. |

Recovery wadding is simple TP dipped into a water/borax solution and dried.
Really.

I know - like I said I made some myself ~ 50 years ago. But it's a lot of trouble considering how cheap it is to buy. |

I still make my own — using 20 Mule Team Borax. I dunk an entire roll, drain it, and let it dry for a couple weeks. The crusty outer wraps are tossed, but it works great. For midpower stuff, I use sheets of paper towels, dunked individually, and hung over a drying rack in my shop sink. I’m a cheapskate ...

I use standard Crepe paper party streamers for wadding. By law this material has to be treated so it is non-flammable. I find it on sale at places like Walmart, stationary or party stores and have been able to purchse the 81' long rolls for as little as $0.25. It sure beats all the trouble of treating and drying TP to make wadding. Besides you can use it for a St. Louis arch effect!

That's a great idea for wadding and far cheaper than the Estes packaged stuff.

I switched over to dog barf for most stuff - the exception being small body tubes (where the dog barf can sometimes act to much like a plug and prevent good ejection. Less than $10 for a bale at Home Depot - last one lasted me 15 years before I had to get another bale (and that included a lot of big, high power rockets with 4" to 8" diameter body tubes). I do still use a bit of the Estes stuff, but so little that a package lasts a year or more so it's not worth messing with anything else. |
