Installation is really easy once you have a properly-sized pilot hole and a use proper sized hex tip on a drill or impact driver.
When I am working with new type of ply or a new size of inserts, I always test-install a few on some scrap, that way I can get the pilot hole diameter just right.
When you use those style threaded inserts with the flange, which side of the panel do you install them into? Do you use them so the bolt is inserted from the flange side or the non-flange side? I don't really know the best way to phrase that question so hopefully you get my meaning.

Install 'em from the back. That way the shoulder will pull it tighter into the baffle when the bolts are installed.

That's the way I've done it in the past, and for the same reason. The only problem I've run into doing it that way is if the the threads aren't totally clean and the insert sticks to the bolt it unscrews the insert out of the panel. I was wondering if anyone else has experienced this.

Hence the reason for the tap and putting a dab of PL on the insert before you put it in. If you do those two things you shouldn't have any issues unless you happen to cross thread the bolt.

I have Baltic birch plywood for two F-20's cut, one has been sitting partially assembled on the work bench for a month, other pile standing patiently.


#2 waiting:



Got some bracing done today, went with the Swiss cheese I saw a few pages back.





Mounting is a single steel ring tapped with 8 holes.





With the JBL 1514 test fit.




No promises when I get back to it. Still need to cut the access, and buy paint to get inside the mouth done before I close up the other side panel.

Looking good!

Using the steel ring for a mounting flange in an interesting way to do it. It looks very nicely done.
