Adrian,

I have some old resins, I'll dig them out. Maybe at a launch we could do a transfer and I could spin one and see how it works.

That is amazing! I just hope I can get that good in the future.

Remember, if the women don't find you handsome, at least they will find you handy!

The nice Aluminum plug was made in a CNC lathe, by the guys at Larry's shop.

That would be cool. Can you use my eyeballed-center silicone/acrylic mold, or would you make a new mold from the Al plug?

I think it would be fine with the mass involved. I'll just hold it between centers and spin slowly to start.

Edward

Very nice Adrian. You should try spincasting them. I'm sure a chopped carbon fiber layup would be as strong and smooth. Tungsten is used to weight golf club heads - you know, the new space ship flying saucer drivers.

SPACE SHIP FLYING SAUCER DRIVERS?!
So the golf guys use it for Rockerty too? 😀

I got the F10 casing out, so the nosecone is just about ready to go. There are a few surface flaws from bubbles that I may try to fix before I fly it, or I may not, since it has such a nice polished surface except for the few flaws. The nosecone is now at 175 grams, including part of a shock cord potted into the noseweight. A fit check with my chute holder and my 29mm H rocket looks good for the nosecone, but it reminds me that I need another coat of epoxy on the rocket! Also, the coupler I installed in the aft end of the rocket may be slightly crooked. If so, I'll need to dig it out, because straightness is so critical. When the rocket is put together, it has a nice look and feel, like it's ready to be chucked quite a distance.

I didn't end up fixing any of the flaws I mentioned above, and the possible slight cock of the coupler probably contributed to some coning I saw during the burn today. I prepped it on Friday, and let the av-bay sit in standby for 30 hours or so with the battery plugged in. No worries, though, since I found out accidentally last week that the av-bay can sit in standby for a week without losing excessive charge. It was nice to drive up with the rocket prepped and ready, though I did do my first sanding of the cone since I took it out of the mold, after the rocket was all together. I had a good signal throughout the flight, and got a direction toward the SE before it landed and the signal went quiet. The recovery was pretty straightforward, since I got the signal back once on top of the hill on the 122 road. Chris LaPanse went with me to locate it, and it wound up pretty close to the road, near the intersection of road 122 and road 49. We had some funny signal dropouts that in hindsight was likely due to us being lined up in the null of the transmit antenna. The flight on the CTI H160 went to 14,214, lower than the 15,710 that RASAero predicted, but that was probably mostly due to the coning during the burn. Top speed was about Mach 1.5.
