Spool Rocket Build Part 2 Engine Mount

I set a 2 3/4" long, 18mm casing in the 3" long motor mount tube, with 1/4" of the casing extending out the back.
To notch for the engine hook, I place the rear bend of the hook over the end of the casing.
The front bend of the hook will be the slit location.


TIP: Todd (Bradycros on TRF) posted a great idea, something I hadn't thought of before.

The engine block gets a small notch on it's bottom edge to fit over the hook end.
With this notch, an engine block will fit flat against the upper bend in the hook and sit straight in the tube.
A simple, smart solution.


Here's the engine block pushed into the front of the engine mount tube against the engine hook.
The cut notch fits over and around the bend in the engine hook.

TIP: When gluing an engine block into a short tube like this, don't put glue in the tube before sliding in the engine block.
Slide the block in against the hook (dry) then add a glue fillet on top.
