that looks awesome!!!
I decided to finally deviate slightly from the plans. The printed tail cone is 110# card stock, but it could be a little more sturdy since there will be fins glued to it. I could have coated the inside with epoxy but since I happen to have a spare cone sitting right there...

... I thought I remembered something HCMBanjo wrote up somewhere about a super cone, or something like that, where two cones were glued together to make one that's more structurally sound. I made sure the seams were 180 degrees apart. Maybe HCMBanjo will see this and give more details about what I'm thinking of.

While the glue dried I decided to test fit section 3. It will fit like a glove.
Section 3 was removed and centering ring 4 was test fit to the top. It was loose enough that it couldn't be put into place snugly, so I added a little glue to the inside of the tube and put the CR in place. As the glue set up I was able to keep moving the CR slightly so that it would be halfway out.
I have no idea how this could have been done if the tube was already glued to the rocket, per the instructions, so I'm glad I finally decided not to follow the instructions to the letter. As soon as the small amount of glue sets up enough I'll add a fillet of glue to the CR along the inside of the tube.
Seems to me, that small paper tabs could be glued to the inside of the body tube that the CR would then be nested between. If the tabs were long enough, perhaps using gussets glued to the CR to reinforce them, you could make the build a little easier (for adding the next section).
I'm sure they'll look great, thanks to your fine work. If not I'll burn you with cigarette butts.Mushtang, this is REALLY looking good. You do very nice work! I'm on pins and needles waiting to find out if those wraps work on the rest of the rocket.
I actually tried building the MACME about a month ago and I messed up somewhere along the way. The nose cone didn't fit right and I wasn't satisfied with it. My wife's favorite rocket in my collection is the Spitfire so she really wanted the MACME to set on her desk.BTW. Almost got all of the MACME Shrew configured as a Template. Once done I can slight minature beer labels in that one if you are so inclined!

I should have worded it differently. The MACME that I built wasn't something I felt could fly, but she liked it a lot and it now sits on her desk.Sounds like a challenge and next project!
Serious...
You glue the tabs to the inside of the segment, slide the CR down so that the tabs are sandwiched between the CR and the segment (thus tightening the fit).
Another idea would be to glue tabs to the CR's underside, then use them to pull the CR up if it gets recessed too far down. After the glue dries, trim them off.
Yet another idea would be to glue a strip of paper inside the segment to act as a shelf to prevent the CR from falling too far down.
Well #&)@$#%!!!!!I sure hope so. I'll try to show a lot of pictures and document any mistakes if/when I make them. I usually goof up at least a couple of times per rocket build.
you may have glued one in the wrong orientation.
3) the top of section 3 showing the same.
Looking over the design, I would guess that you may have used an incorrect ring someplace, or you may have glued one in the wrong orientation.
If you could do 3 more pix, it may help.
1) a pic of those two sections together, but from 90 degrees around (so I can see the solid and dotted align,net lines)
2) the top of section 2 showing the centering ring as well as the alignment notch and alignment line
3) the top of section 3 showing the same.
Additionally, re-review steps 16-20, as I am doing. We should be able to figure this out
And, no worries, whatever it is, it can be fixed.

Ummm. . . Beer! Silver Bullets or Banquet. Pure Rocky Mountain spring water. Wish I could take the brewery tour every day.
That rocket looks mighty crooked and it is made out of old beer cans! Here, hold my beer and let's see if it flies
Hey that's true! Cool.Mushtang...you have Jim Flis on your Tiger team working the problem!!
If you're offering I'm accepting!! Thanks. If you have a piece of BT-70 that is 6" long let me know and I'll PM you my address. 4" looks like it would barely work, but having some to cut off each sloped end would make it easier to cut accurately.BMS sells BT-70 tubing really cheap and they ship very fast.
I have some left over BT-70 I could send on Monday. How long does it need to be? I can see if my scrap piece is long enough.
Another reason this forum is so wonderful!
I'd gladly launch a rocket...then hold up a beer with you any day. (in that order)Agreed! I love the information from other rocketry builders, and when they give you actual STUFF it's cool too!! And as the one that created the wraps for me you were the first one on this Tiger Team. All of you will deserve a beer when this is finished.
