A few things dear friend:
1. wonderful!
2. great job!
3. well done!
4. what the heck of a workshop! it's huge!
5. pretty clean cuts on those rings, they turned out great!
6. don't leave the print shop without the prints!
7. aahhh those canted tubes, I'd rather skip on them! the project will be already expensive to fly, are you really sure you want a 5 motor cluster with 4 K250???
8. you're flattering me!
Keep up the good work!!!
Getting closer!
The wood work fits perfect!
Are you pigmenting the epoxy as I DO?
Thanks for the nice comments, I'll see if I can help you.
Sorry I didn't document it.
No real problems in building.
It used 8" sonatube for the lower half & stacked up foam donuts that I turned on a lathe for upper section.
Has a 3" cardboard tube up thru all the foam in upper section.
Fin can is removable so I can replace clear Lexan fins if needed.
I used 4 layers of panty hose & epoxy over the complete rocket. filled that with high build primer, than rattle can brown paint, a light coat of RC car pearl paint, rattle can clear.
The label is an upscale of my own for my Home Brew.
The rocket has about 1 1/2 pounds of weight in the nose.
Half caliber of sability.
Rocket is 33 1/8" tall, CP is 14.19" from top.

Da man behind the... bottle!
To get the nose cone off do you need a bottle opener or is it a twist off???
looks good. What motor are you planning to use?

:roll: authenticity man authenticity!
I would have "buried" bottle in the top so when the flight was over you could crack that and drink from the rocket

in europe we have big problems with motors, and the worst thing is the cost of course!!!
for example, an AT K250 in USA costs $260, in europe the cost is around $420.. as you can see, launch a K here is like to launch an M in USA!!!!!
i can't find anything interesting for this question
how much thrust gets lost in a 10° canted motor???
what's the rule of thumb for it!?
i have to fly this rocket with a cluster of 4 I540WT or something similar... with all the risks of a just enough powerfull cluster... if one motor fail to ignite, there is no chance to see the SpeedWeiser again.
Rule of thumb would be to take the cosine of the canted angle times the thrust curve of the motor. For 10° that works out to about 98.480% or a loss of about 2.52%
hope this helps.

Why not use 5 I540s? There is 5 motor tubes, right?
