Estes Thor Agena Build Part 19 Turbine Exhaust

The turbine exhaust is made from a 3/4" long piece of 1/8" diameter launch lug.

Step 12 of the instructions has you cut and glue the turbine exhaust (lug piece) in place before the super detailing is done in Step 16.
Refer to Step 16 before gluing on the turbine exhaust lug. You can't do all the extra detailing if it is already glued onto the rear centering ring.

The instructions say to cut it to 3/4" long, then trim the top curve. Leave the lug long for now, for easier handling and cut it to length after forming the top.

Cut the top of the lug at the angle shown in the instructions using a sharp razor blade.

Sand the curve into the top angle using 400 grit sandpaper over a dowel.





When sanding a lug like this, the outside Mylar wrap can stay attached and turn inside the lug.

Coax the turned layer out and up with a sharpened dowel.
Sand of the Mylar wrap with more 400 grit.

You may have to repeat this a second time to get it all.

After the top is formed, cut off the bottom so the lug is 3/4" long.

Taper the new flat end so it is at the correct angle to the large nozzle shroud.

I'd recommend using CWF to fill the seams on the turbine exhaust lug before going any further. It'd be hard to fill the lug seams after all the "super" detailing to come.
