Hey guys. I received my kit today (thanks for the fast shipping, Danny).
I noticed that the fit of the tube connectors was pretty tight - er, really tight. I think I could pound them in, but they would certainly not be easy to remove. I've never used these before.
I measured the holes in my rear panels and they are a few thousandths smaller than the 0.4375 spec. Maybe the material has swelled since I brought it in the house, or maybe the cuts were off a little, which is possible, at such small tolerances.
In any case, make sure you check this fit. Even after running a 7/16th (0.4375) drill bit through the hole it was still really tight. A little wiggling of the bit gave a good balance between a tight fit and possible to remove. Again, I've never used these before, so I'm not sure how tight it should be.
(pardon the cross post, I want to make sure everyone sees this)
Edited to add Danny's response from the other thread:
You don't remove them. You install them and you're done.

And you can tap them in gently with a little hammer. I line the back side of them with a little Silicone too.
