Let's see how it works without strut pole

Here's new strut pole, M16 threaded rod full of extensions

No more flex

Video with bolted hatch

Lock was still flexing, had to do something

Much better

Now the hinges started to flex. Fixed those and put new box in for next show

Strut pole wasn't looking so good, much better.

Testing new subwoofer box.

Once again same subwoofer failed, fixing time

Working again
