Semroc Saturn 1B, Build, OOP #KS-1, Part 35, Vector Control Jet Housings

TIP: Here's one way to make sharp circle recess nozzles.
You can also to this to make recesses for screws on scale models.
This idea is based on something from an old CMR D Region Tomahawk kit.

The end of a 1/8" brass tube was filed to a sharp edge towards the inside diameter.
This was polished on 220 grit on a block.

Here I'm practicing on some scrap basswood.
Press and turn the sharpened end in the wood.

Knock out a thin layer of wood with a sharp knife.

Dampen the blunt end of a dowel, the tip is about the same diameter as the recessed hole.
Press and rotate the dowel tip compressing and smoothing the middle of the recess.
Let the wood dry before proceeding.

With a Q-tip, apply a bit of medium CA in the recess.

Quickly press and rotate the blunt dowel tip again. Don't let the dowel tip get glued in the recess. You are just trying to "set" the shape of the circle recess.



Here's the finished recess. Practice a few times before working on the model jet housing pieces.

Notice there is some CA glue outside the circle. This will be lightly smoothed with 400 grit.
