I'm going to tell you that I cheat though.
I have a good microscope that I use to help me carefully remove the old glue from the phase plug.
If you don't remove the old glue it won't sit perfect when you glue it back in.
Working in the microelectronics industry has spoiled me. Besides, I'm old and can't see that little stuff anyway!

Enjoying Altec Speakers since 1972
I've installed a couple of tangerine phase plugs, clean with wire brush lightly, use super glue and you'll should be OK.
Going to do some more testing this weekend so stay tuned. I think that all of this hard work might actually pay off.
Wow! I finally got around to assembling everything today (woofer, horns and driver, crossovers, etc.) put it all together and it works wonderfully. I'm really surprised. I spent about 30 mintues listening to Doobie Brothers (what were once vices are now habits) and it all sounded great. Pictures to be posted tomorrow.
Touchdown!
Really? With my (your) 414's?
Enjoying Altec Speakers since 1972
It's all up and running and I'm a little surprised that it worked out as well as hoped.
Here is a recap of what I did.
Removed 802-8G. One was good - one was extremely rusty
Sprayed WD-40 on bad one and let it sit. Started cleaning with a small wire brush. Then moved to wire brush on a drill.
Worked on cleaning out the gap that had a stuck diaghrapm. Used a small utility razor blade - spent approx 1 hr on it. Used vacume and air compressor
Used paper speaker shim's to clean out the gap more extensively - spent another 2 hours +
Clean all with hot water and soap
Cleaned and polished 32B horns with Armorall
Installed diaghrapms that I had sitting on the bench
Refished cabinets with Howards
Installed 414C (purchased from member Ron locally in the Portland area)
Removed and cleaned crossover network.
Installed all items
Plugged in and she rocks.
I let it run for awhile and then cranked it up a little. All sounds good. Still have some work to do as I think that I'm going to move the speaker connections from underneath to the back of the speaker cabinet. Additionally, I think that I have to replace one of the LPADS.
Here is a summary of the pictures.

Thanks to all for your support on this project. We all learned together.
Nice job! Glad they sound great. What is the Howards product you use? I might do my Model 19's and 14's this spring--they could use a little oil (or whatever that Howards stuff is--I think AB recommended it once in a thread here too). I was also wondering, are you using the Model 15 crossover in it's "stock" configuration with the 414's or did you customize it at all to compensate for switching the stock woofers with 414's. Or was no tweeking to the crossover necessary--did it just sound great as is with the 414's?
