Estes Red Max Build, Part 5, Nose Cone and Fin Marking



One of the nose cones had "scars" on it.
It looks like some plastic flash was cut off at the factory.

It looked worse than it was and sanded smooth with 220 grit sandpaper. 400 Grit was used before any spray primer.



This was one of the first kits to use this style of card stock fin marking guide.
I did have trouble getting it over the BT-60 tubing. The center hole was slightly enlarged with some 220 grit.

TIP: The engine mount was glued in first before marking the fin lines. Sometimes it's easier to glue in the mount first. You avoid any trouble lining up the engine hook under the launch lugs as the glue is quickly setting up.
So the engine mount goes in first, then mark the tube for the launch lugs and fins.

Two guides are used. Set both the "flats" on a table and mark with pencil in the V notches. Line the launch lug line directly over the engine hook.
Extend the notches down the tube with an aluminum angle.
