Centuri Quasar Clone Build, Kit #KC-7, Part 6, Making The Fin Pod Jet Nozzles






The rear nozzles need a tapered piece and smaller tube nozzle.
Three tapered pieces were made from old MPC Mini Jet nose cones from their old part accessories kit.

The shoulder was tight in the BT-5 tube and was sanded to fit.



A reference circle was drawn in pencil and the taper sanded in with a block.

The nozzle was cut from a Bic pen "Stick" pen. 




Here's the rear nozzle!
I could have purchased the resin cast pieces from Sirius Rocketry, but I vowed to make this a spare parts build. 
My clones are usually close, but not an exact replica.

Centuri Quasar Clone Build, Kit #KC-7, Part 5, Making The Ramjet Top Cones




I found this picture on the Sirius Rocketry Moldin' Oldies web page. The same ramjet and nozzles pieces were also used on the Centuri SST Shuttle kit.





The picture was sized to a BT-5 diameter at .541".
I did my best to trace the pieces. These are close but not exact. They are just a reference for making equivalent size assemblies.





A dowel was carved to a point.
The chip cuts were smoothed out with 220 grit on a block, followed by 400 grit.


These were sawed off at the pencil line and the flat base sanded flat.

I carved and cut nine of these.
I'll pick the three best cones and use them in the build.
