Centuri Vulcan Build Part 5 Bulkhead Ridge


Sand the edge at an slight angle to match the inside wall of the body shroud cone.
The angle in the picture is a little exxagerated for clarity. Try to match the angle of the finished cone.

This might help get rid of a ridge that can be seen when the bulkhead is pressed into the cone. The bulkhead presses against the cone forming the end area into a rounded triangle shape.


I wanted a internal launch lug, instead of gluing the lug down the angled cone body.

NOTE: This internal lug idea didn't turn out quite as I hoped. The cone body turned out longer and thinner than I though it would be.
The rounded slot that had to be cut into the front end of the cone body (for launch rod clearance) ended up being 3" long! I thought it might be under 1" long.
There were good reasons why Centuri wanted you to glue the lug under a fin and against the angled body.

The lug will go under the body in the same location where the engine hook would normally sit.

Set your rotary punch to the largest barrel and punch a 3/16" diameter hole.
TIP: A 3/16" hole fits a 1/8" launch lug perfectly.
