Another option would have been to leave the excess length you had on there, shape it down to the nub left where the center is, then remove the nub last. No filling needed then. Looks great Captain!
I honestly don't know how I pulled this one off. I'm really not that good. It had to be by the grace of God, because there were too many opportunities for failure. And yes, I giggled like a little girl when I first put it in the rocket!

Nosecones as art! Really impressive.
I've been absent for a bit and I'm sorry I missed this thread.
This is going to be a really nice upscale Qquake! If it flies like my daughters Cobalt, it'll take a H or an I no problems.
(BTW, the stock Cobalt needs about 15 grams of nose weight to handle a "C", and it really hustles on that. Hope that helps you in calculating what motor you can handle).
A thing of beauty Jim,wish I had your talent.As always another fine build.
Color me blown away! Stellar job on that nose cone, really great job of free hand turning. You have a really good eye for this. The whole rocket looks awesome, nice upscale.
You've done an amazing job turning out that nosecone, Jim.
And to disagree with you a bit, you really are "that good" in crafting your rockets. I've learned quite a lot from you.
Um...dust masks are for sissies?
Even though I don't typically build anything very large, I still learn great things from your builds.
Someday I'll get a lathe and do it right.
My leetle Quest Cobalt (and it's lengthened brother "Orange") are favorites with a little nose weight and a B6-4.
I also found out a slightly longer body tube required much less weight for stability.
You mentioned a concern about repeating your methods.
Most guys need to hear thing again to drive a point home. (Just ask my ex-wife)
WTH man! You build all of these cool rockets, you have all of those awesome tools AND and and you have a FULL head of hair??? That just seems unfair too me. If you also own a cool car that would really be too much.
Just for fun, I took a couple of comparison shots with the two 3" nose cones I turned recently. Man, that Cobalt cone is huge compared to the other two!
Amen, brother!
If you didn't need the ballast for stability that nose cone is big enough that you could hollow it out like turning a bowl.
Think a CTI I150 will boost it or will it take a J? Not sure of your Cobalt's weight.

I'm sure the I150 won't have any problem lifting it. I doubt it will weigh more than 3 lbs. when finished......

According to Open Rocket, it weighs about 6.5 lbs without a motor. It sims to 1600ft on an I150.
Hollowing it out would be a nightmare. How would I attach it to the lathe backwards?

This is inspirational Jim! Thank you for sharing. Can't wait to see them in person.
I keep having this idea of turning a segmented circle NC--something like this spinner, but with fewer, larger pieces. Like maybe 4 across (like you did, but with two kinds of wood) and then cut in half and rotate 90 degrees.
Only my turning is nowhere near what you do.
Ari.
I'm not sure how I missed seeing all this. Nice work as always!
I need a lathe. Nice work!
