Centuri Quasar Clone Build, Kit #KC-7, Part 7, Gluing Up The Ramjets

The plywood stop disk (from my Odd'l Birdie and Sputnik kits) was glued to the top of the BT-5 sized coupler.

The hardwood Ramjet cone is glued on top of that.

The Bic pen segment nozzle is glued onto the narrow tapered end of the nose cone segment.

A "fillet" of CA glue was applied around the joint using a toothpick.

Both the front end Ramjet and the rear end 

Nozzle are recessed 1/16" down inside the BT-5 tube.

All three are ready to go - 

To be glued onto the outside edge of the three fins.

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.
