Semroc "SST Shuttle" ramjet nose and tail cones
Quote:
Last week my obsession was trying to approximate an Estes Saros with Semroc parts. (Close enough, but the cigar won't be from Havana. ) This week, it's a Centuri Quasar with a balsa tailcone (instead of a paper boattail) which actually *looks* like the 1972 catalog picture: http://www.ninfinger.org/~sven/rock...a/72cen026.html (I'm thinking that paint job looks like gray instead of silver, like the instructions say.) http://www.dars.org/jimz/kc-7.htm I'll have to ask Carl if he can turn a boattail with the center bored out (for the Quasar, it would have to be a [making up a part number] BL-1610, 'cause BT is Estes' designation for "Body Tube," so conceivably BL could stand for "Boat taiL"). Of course, if I decided to build an SLS Quasar, I think I might be able to twist Carl's arm (gently but firmly, of course) to see if he could make 175% balsa upscales of the ramjet intakes and exhausts... and the boattail.

Jay,
Don't forget the "cockpit' on the Quasar nose cone. This is a resin copy that JimZ made.

Give it a "TC" designation, for "Tail Cone"...

"Faking" Centuri PNC-165 nose cone
Quote:
Yeah, I just didn't bother trying to model it in RockSim. I had an original USS America "back in the day" (which had the same PNC-165 nose cone). Steve "Austin" (Texas) Rogers did a 2.4X upscale of the Centuri Quasar: http://homepage.mac.com/srogers4/ro...asar/index.html ...and he has a couple of pictures (overhead and side view) of the PNC-165 that I'll try to replicate the cockpit from. http://homepage.mac.com/srogers4/ro...quasar-nose.jpg Maybe I'll have to "fudge" one out of cardstock after I extrapolate the proper dimensions. Then I was thinking that I'd have to glue it to the nose cone *before* I did my usual "Wood Hardener" treatment. Of course, I'll have to round the pointy Semroc BC-165 slightly before I do that, as well. Cheers, --Jay |

See, I keep thinking it's a good idea to keep you around, Craig! Cheers, --Jay |

Estes used "BTC" for the boat tail for the old V2 (BNC55F for the nose, BTC55Z for the tail)

So Semroc has discontinued this kit.
I bought an older Centuri Sst but it is missing the nosecone. Does anybody have an idea what I could use to replace the original?

You should be able to check the Semroc site for a parts list still for the kit. If not, just email e-rockets. They own Semroc now.
