I've posted a PDF of the 1962 Coaster Corporation catalog (http://www.payloadbay.com/article-coaster-corporation.html) on PayloadBay.com.

There are some interesting things in it. For example, fuses are available for deploying the parachute.

Roger,

Can I post this on YORP?

I have an older version up here:

This is an interesting document. I had previously known and posted that the original Coaster BP motors were nothing more than fireworks or pyrotechnic "skyrockets". I had discussed this fact with Randy Lieberman in a past conversation and he verified that for me. I also had known that the original Coaster engines did not have an "intergral" delay train or ejection charge; this catalog verfies that it used a fuse delay train along with BP as a "burst charge".......

I am guessing that those 2 chemicals are charcoal and a premix of sulfur/KNO3....mixed together you get BP.

This is cleqrly fireworks technology. Burst charge has a different meaning for fireworks than ejection charge does for model rocket engines. Of course they basically end up doing the same thing.

I now understand why Orv Carlisle sent a cease and desist order to Coaster Corp alleging patent infringement in 1959.

Evidently Menford Sutton had by then, seen the MMi Rock-A-Chute motors with their integrated delay train/ejection charges and borrowed his design. Of course the Orv Carlisle model rocket engine itself was just a new combination of old fireworks technology, so Menford ignored the letter.

On the other hand, as early as 1958 Richard Goldsmith(central Rocket co), a very good and old friend of Orv Carlisle and fellow pyrotechnist, had published several documents showing how to make what he called model rocket motors that are pyrotechnic skyrockets with an integrated delay train/ejection charge..... There's no doubt in my mind that Goldsmith was well aware of what Orv was doing as Goldsmith later sold Orv's Rock-A-Chutes and also was an old pyrotech buddy.


Thanks Jadebox for this.

Fuses weren't uncommon in rocketry at one time. Most people think about ignition, but they were used as delays for ejection, for dethermalizing gliders in competition, ignition of separated upper stages, etc.

Up until the BATFE stuck their noses in the hobby, we were able to use thermalite, which comes in several burn rates. :cool: Many people didn't know about fuse use outside of the competition folks because Estes/Centuri were their only rocketry connections. Once HPR became popular, thermalite became almost mainstream.

Hmmm...those models look almost... clone-able.... ;) :D

Now, if one of us decides to clone them, and the pattern of subsequent developments continues...

Mitchell Pines once showed my a slightly-later-vintage Coaster catalog. It had booster motors, and entries for the Centauri boost glider. Mitch had a few actual Coaster rockets. Maybe the Centuri, for sure one of the three fin and a nose cone models. He flew that one!

The three fin and a nose cone models in the 1962 catalog look very sturdy and retro. I'd love to get more information on them.

Parts-wise, we could probably guess that they were similar to early Centuri "large scale rocketry" kits. Centuri carried Coaster motors.

Harry Stine's models includes the Saturn Probe 1. It uses the 2.0" tube (our LT-200). Bob helped me get some good photos of the fins (one was broken off to get it in the drawer). I just have not had the time to release the parts and was not sure how much interest there was in Coaster.

Just like the RDC Rawhide, it would be a rather unusual retro-repro that would illustrate a rocket from a company other than Estes or Centuri. (Even though it would be an ancestor or predecessor of Centuri from an earlier time - kind of like the Neanderthal. :D )

FSI used thermalite fuses for igniters.......

So did I....attached to an igniter for special projects. :cool:

I'd love to see a couple of the Coaster kits cloned...

I'd love to see soem plans or the retro-repro kit :)

also - these would be MUCH more popular once the Quest motors come out .

soon, I hope ! :D

Is anyone interested in seeing the Coaster catalog listed for sale on eBay? I'd like to see if there's any interest in it before I decide if I want to sell it or keep it.

Wow! Were those prices high for 1962!
