It's something to look at since I'm waiting for the glue to set.
Using for the top face of the FIBs, Lexal adhesive, since I have terrible luck with hot glue and gorilla glue. It's sort of like silicone, but stronger and more stable than silicone. Is thick like silicone, and does not drip or run. Laminated the front panels of the cornu speakers with laminate glued on with PVA, and that I think may take a while to dry.

Azdoug,
Are those the FIBs with the TC9FD drivers? It is real sensitive to damping with stuffing. I had to slowly remove it from the bottom where the flow turns 180 deg to get balanced bass. It takes some but not too much. Best way is with mic and measurement program to get balance just right. Good luck!

hey xrk971 - perhaps you can sometime try the augmented klam cabinet type below in foam-core (the patent fails to reference Karlson) -can you see any use for it?

I may try a shape like that next, wrap it around a formed holey brace. Flat baffle wide enough for driver.
Slot loaded Open Baffle bi-amped with DSP
This was made of cardboard but could have just as well been FC. In case you are interested it is described here: http://www.diyaudio.com/forums/full-range/249984-cheap-fast-ob-literally-7.html#post3805024
Sounds great and easy to build.

Yes, I made essentially a bottom lid that fit tightly and held in place with tape during adjustment. I then sealed with glue once good. How did the FIBs turn out? Any photos?
ERMAGOSHHH...
Hot glue on my fingers. !!
😡
This foam core idea is pretty cool.
Hot glue... ugh.
I started building mine today from the $1 Dollar Store.
Found the same thing, but nicer quality Elmers foam core at WalMart for $1.47.
They also had it with a blue backing for a bit more $.
But lucky me, the blue backing was in the slot where the $1.47 white backing was supposed to go, so I got a few sheets for that price.

I buy the Elmer Foam Core sheet at a school supply store near my home, if not mistaken it is 3/8" thick, good quality. I made a pair of uFonken and a small TL using Elmer's.
You get used to it after a while and it stops hurting. Manly man stuff this hot glue. 🙂 If you wet your finger with water first you can use it to smooth a joint with a nice fillet.
My local supermarket carries the Elmer's and it is mis labeled price. Their policy is to give it free if mismarked - I got several sheets this way.
The dollar store stuff is ideal for parts that need to be curved and the Elmer's is good for exterior panels especially the baffle where the driver mounts.

I use nitrile tipped gloves - also from dollar store. They are not too thick and so I still have enough dexterity. But, they are just thick enough to stop the burns. The glue, once hard also peels off them very easily. Highly recommended.
I used pieces of scrap foam for a lot of places on my last two projects. You can shape it to whatever you need - flat, pointed or with a radius. If the hot glue builds up just clip the end and you have a brand new tool 😉
I wear disposable latex gloves when using hot melt glue. No loss of dexterity & enough protection. If you catch a big glob of glue, then you can rip the glove off quickly.
Cheers, Jim
Yea, yea, yea - we all know you apply that hot roofing tar with your bare hands.
Some of us are sensitive artistic types.and still need our finger tips at concert time

Some of us like to keep the feeling in our finger tips for more delicate activities😉
She likes it a littlerougher than that! 😀
Sorry, I couldn't resist.
I am a auto tech. by trade, I can't feel hardly anything with my finger tips anymore.
This foam core stuff may be the PERFECT avenue for me to pursue.
