Stripped the veneer to repair the cabinets.

Currently applying first coat of Aquaplas to the cones in prep for reconing. Don't know which dustcap look I like best. Innie or outtie?

Thanks. Going for full red oak veneer. Magnets under veneer to hold the grill. Golden oak stain and Tung oil to match the L36's I rebuilt.

They will be beautiful, and a great match for your WOPL !
Post pictures when you get a chance.

My favorite non-Pro JBL speaker, very under-rated. I had four of them and the house was rockin'.

Tung Oil is great BUT, it requires reapplication and reapplication reapplication. I used it on my Cornscala's and I'll never do it again.

Way easier than a French polish.

I see you mentioned applying the aquaplas to the cones,isn't on the BACK of the cone on this model? I didn't know you could buy the aquaplas material and diy it.

The original cones had black Aquaplas applied to the face of the cone which increased the mass and stiffness of the cone.

I can't say with absolute certainty that this is Aquaplas, but I got it from ebay and the first coat has improved the stiffness of the new cones which is what is required.

Nice. I didn't know that JBL put gray aquaplas on some models

The 127h model woofers for certain. I'd like to try it on the 125a in my L36's, but I don't know if I'm that brave.

I started using tung oil refinishing M1 stocks as a hobby as that was the original finish before Japan cut off supply during the war. Once cured, it is very hard, waterproof, and easily repaired if damaged.
The 2 biggest destroyers of speaker enclosures are children and liquids. Both are mitigated with a well applied tung oil finish IMO...and it really makes the grain pop out.

Using it on my AR XB turntable plinth and JBL speakers. Never thought about gun stocks. Excellent suggestion!

Got the cones installed. Just got to wait for a full cure on the epoxy and solder to the terminals. Glue down the surrounds and run some test tones.

 

[Oldskoolfan]

Couldn't wait for veneering the cabinets. Had to test'em.
I. Am. Pleased. I really like the magnet mod.

Very nice work...

Very nice work...

Thanks Joe. Gotta get my wall unit finished so I can connect Val to the 4410's. They're only rated at 125 watts, but that's where your meter switch comes in.
