It's all been primed, painted and striped up. All that's left to do is join the two sections and install the laundry. No more B motors for this bird.

And PRESTO! Looks like new again. I'll be interested in seeing what apburner does with it. I hear there's an upscale in mind. SO, has anyone figured out what the Acronym means? It's prolly too easy and you can pm me your answer if you like. The real title is not suitable for the forum.

OK I finally got back to thinking about this rocket. I have an 8inch sona tube I have cut 8 inches off of. I cut the upscale internal fins and then thought to myself while pondering the size of the tube that that is begging for a 38mm tube instead of a 29. All the fins will be 1/8 baltic birch plywood. And I will be gluing it together with epoxy so I figure this thing should be able to handle a mid size I motor as long as I keep the thrust down low so it doesn't go to fast. Maybe an I180 skidmark for first flight. If it survives that this a full I 5 grain I125. We shall see I still don't have a clue about what I will do up top since the 38mm tube is out of scale a bit.

If you're concerned about it looking exactly the same, don't. There are no rules here. But just in case you are, a 38mm tube is slightly bigger than a BT 55. After scaling, your upper tube would roughly be the size of a BT 80. You might have to crack and hollow a wooden nose cone that big though.
 
Actually a wooden nose cone that big might be something I could use. The weight would make this thing a bit more stable. I'm thinking a 38mm tube on the bottom and a three inch short tube on top. The transition will hold an altimeter with the hole on the larger half for vent. and then a dual deploy. Lower half splits off with a long shock cord doing double duty as a streamer. then the upper 3" tube would hold the parachute. I know I will be flying this High power mostly H's but an I is not out of the question.

An 8" fin can with a 3" airframe....that should look just fine...uh....er....just as ugly? LMAO. At any rate the tube sizes seem adequate.

I wasn't sure my efforts were going to pay off but it would seem I was mistaken. A slice here and a slice there, a little carving with the knife and some sanding was the trick. This was test fitted with a new tube and showed I still had a little cleaning up to do.

I looked at this picture again tonight, and BAM!! .....2 stage!
Have the upper inch or so of the inner fins seperated from the bottom. Glue the top fins to the upper Bt and the bottom to the can.

I'm looking forward to your build thread. Need the specs?
 
Ya, but,ummmmmmmm, Ild have to go out and buy me a lathe...man,that would suck...:wink:
I dont think Sandy would understand the importants of it...:lol:
They are a tough item to come across for short coin.
Anywhoo--Im thinking if I give it a go, Ill use what I have in the junk pile,,it will be another brother from a different mother,but a brother just the same.The NC could prove to be interesting.
However,ya,the specs will be nice to have,Thanks.
 
Thanks for the heads up. I know what you're getting for Christmas this year. Let me know if you are going with the given specs or planning to upscale so I can grind the right nose cone.

LOL. I just realized that you only used 3 inside fins. I have already glued 4 So I will use 8 outside fins. And the inside fins are different because I didn't look close at the pages you gave me and just assumed So there is another difference. But it will be strong and should be able to fly on any size 38 I throw at it. As long as thrust is not to much so top speed stays low. :y:

Pictures! We want pictures!!
 
Oops forgot. I will shoot the outer tube with the main body tomorrow morn. I can't really do anything right now because I just coated the sona tube with finishing epoxy to make the inter surface more sanding friendly.
 
And EGAD you don't want a look at my bench. It is full except for the small space I have pushed stuff away to work in. LOL. But it was worse a week ago. I guess that progress:wink:
 
OK I went ahead and brought them upstairs and put them on wax paper. and took. Pictures. The black piece you see it a small piece of carbon fiber flat rod I had laying around. Thought it might make a good looking conduit.

OK finally got to work on it some tonight. Still not sure if I am going with 3" or 2.56" upper tube. I guess thats the next decision.

Oh and the center tube is a 38mm LOC MMT. Long enough to fit a J motor into. Probably won't but it's nice to have options:wink:

This is wild seeing this rocket come to life from another place. I went back to view my scaling in Autocad and as it turns out, a 3" tube fits the bill. Actual scaling was 2-63/64". Close enough.
 
Oops. Ya I now remember reading that. That was a really close call on 4 seconds. but it flys great. I think mine will go up on a one of the CTI single grain G's for first flight.
I really have no idea how high it will go but should be a fun flight. I really like the skidmarks so it might sparkle while going up.
 
It might have been because it was underpowered, but it did seem to slow down rather quickly after burnout. Could also be a drag issue. I thought it would go higher than it did but I was really wrong. Hence having to rebuild it. It weighs 4.5 oz and I guess I should have been more careful picking out a motor. A G motor in yours should give it a nice ride.
 
LOL. I just did an Open rocket on this thing. Don't know if it will be accurate but it says a G69 skidmark will only take it to 314 feet. That seems low.
I am not real good at this open rocket thing so I probably made mistakes. It also does not have a parachute in it.

Started playing with it. No matter what motor I choose it will not go over 550ft. Also I scaled it down in half and flew it on a B6. The 2 sec delay was as close as I could get the 4 lawn darted. And it only went 54 feet. Pretty close to actual I think according to the video. LOL.
