Semroc V2 Build, Part 8, Launch Lug Trim

The original instructions give a full size template for cutting the turbine exhausts and pull out plugs from standard launch lugs.

TIP: Draw pencil lines extending the cut lines beyond the launch lug sides. Why extend the cut lines? When you set the lug on the full size illustration, the lug covers the angled cut! The extension lines give you something to line up the blade.

Launch lugs are tough to cut, they can be easily crushed. Be sure to use a new, sharp razor blade.

Set the lug over the instruction drawing, line up the blade on the extended pencil lines drawn earlier. It might take some "sawing" back and forth to cut through the lug.

Cut the back end angle first, what's on the right side of the drawing above.
TIP: You'll find it easier to make the first back end cut and sand that edge smooth. Then make the second longer forward angle cut. You wouldn't be able to sand the edges when the small piece is completely cut off the lug.

I actually cut four of each and picked the two that were the closest in size and shape.

Try to get all the sides cleaned up before gluing onto the tail cone. The inset picture shows a clean cut and sanded first cut.
