Centuri Finless Build Part 4 Engine Block and Kevlar

The engine block (or thrust ring) was notched for the Kevlar.
I've been using a small diamond file with good results.




After tying on the Kevlar, the block ring was glued into the rear of the ST-7 tube. An engine casing was marked 1/8" from the end.

The Kevlar was fed through the casing so it'd be out of the way when gluing the block in place.
The engine block was glued inside the ST-7 tube by sliding the casing up to the 1/8" mark.
