Mark II how important are you??
 
Done maybe already, just point me in the right direction. Why is the MARK II "historically significant"? What are the details of the bottom of the nose cone, parachute, and the engine mount? What about the model Bill has of his Dad's??? Is that particular model "historically significant"?

Could the Mark II have been the first Estes rocket to break apart upon ejection instead of using tumble recovery? I know it's one of the few kits to use the BT-30.

Semroc sells a clone of the Mark II
Here is a list of the Estes first 10 kits
K-1 Scout
K-2 Mark
K-2A Mark II
K-3 Space Plane
K-4 Streak
K-5 Apogee 3
K-6 rAnger
K-7 Phantom Original BT-20 no fins
K-7B Phantom BT-50 with fins
K-8 Sky Hook
K-9 Sapceman
K-10 Cobra

From what I understand, the Mark was part of Model Missiles and G Harry Stine. If this is not correct, please correct me.

We are talking Orville's roc-a-chute Mark II with the crayon sharpener nose cone, right?

Orville's Mark II Rock-A-Chute
 
1 Attachment(s)
From my point of view, Orville's Mark II was the first practical model rocket. The first rocket he made, Mark I, looked like fireworks of the time. So, I'm guessing, he wanted to get away from that look and made the Mark II. That would make the Mark II the first model rocket that looked like what we think of as a model rocket. That is, in my opinion, what makes it historically important.

On the Ye Olde Rocket Plans site,

http://plans.rocketshoppe.com/publications.htm

there are 2 good copies of articles about the Rock-A-Chute rockets. One is about 9 down "09/58 Rock-A-Chute Aerobee-Hi Review"

http://plans.rocketshoppe.com/pubs/...8/9_58AmMod.pdf

the other is farther down after the Estes stuff, "10/57 Rock-A-Chute Article"

http://plans.rocketshoppe.com/pubs/..._57Mech_Ill.pdf

These show some photos. Also see the article in Sport Rocketry in the July/Aug 2007 issue. It's about a build of the Mark II using an original Leeds Sweete plastic crayon sharpener. Some of the information that the modeler used in the Sport Rocketry article came from Bill Stine at Quest. I am hoping that this information will be a part of the "The Model Rocket Museum" mentioned in this forum and on the Quest website.

This is also one of my interests right now, as I too have an original crayon sharpener to use as a nose cone. A buddy of mine re-created the Rock-A-Chute logo for me to make a decal for the rocket. I'll post it here for all. I will be posting that build, along with an 3X upscale build of the Mark II, hopefully in a few weeks.

Somewhere on this forum, I read that someone had talked to G. Harry Stine and said he had bought a Rock-A-Chute Mark II as a kit sometime in the late 50's I'm guessing. So, this would mean that Orville kitted the Mark II and maybe sold some locally from where he lived. That would make the Mark II the first rocket kit ever sold. I love this history stuff.

Thanks, Rick. Mind if I put this up on YORP as well?

check out the 5/1970 issue of Model Rocketry magazine over on Ninfingers, "The First Model Rockets" by G. Harry Stine.

You really ought to consider alowing somebody to make a mold clone of that Leeds Sweete plastic crayon nose cone so that we could all make real reproductions of the Mark 2.

Nah. We've got Estes on the brain and forgot about that one. :o At least I did.
In that case, it's pretty obvious. It can attain altitude and sharpen the pencil that you use to fill in your log. If they could have found a way to put a Ginsu knife blade in there, we'd REALLY have been talking historic. :rolleyes:

Please feel free to post and use the logo.

I would not be opposed to someone casting the crayon sharpener nose cone. I have not yet tried my hand at learning to cast things. If you know the right person for the job, let me know and we will see if we can figure it out.

I also forgot to mention earlier that there is a great article about Orville Carlisle in the premier issue of Launch Magazine.

Here's a few photos of the sharpeners.

Ya know, this is off topic and all, but I had to interject here...

Everytime I see your avatar, instead of the top of Patrick's head, I see a NAR logo.

Weird, huh?
