Semroc Mini Optima Build, Part 5, Coupler Bulkhead

The hole in the plywood coupler bulkhead seemed small. I was concerned the screw eye might split it.

The hole was enlarged with a small rat tail file.

The instructions tell you to turn the screw eye in until the threads just disappear.
TIP: Don't turn it in beyond the threads or you'll have nothing gripping the screw eye in place. This bulkhead is only about 3/32" thick.

I added a glue fillet on the inside.





The bulkhead is glued just inside the edge of the black coupler. Positioned like this you can add a glue fillet.
