From Studo -> Home Finish

[Rolf]

As many of you know I bought a pair of 4242B's from Guido. These was painted black. I have now started the process to get them into walnut finish.

Here are some pictures of the progess so far. Next step is to attach massive walnut on the front edges, and then buliding the grills. More pictures will come.

Nice job on matching the grain pattern from one side to the other!

Nice Rolf. Is that veneer "Norwegian Wood"? Sorry, I couldn't resist.

[Guido]

Good work Rolf

Keep us posted!!!

[Val]

Nicely done. Did you use the iron?

[norealtalent]

Nice job with the wrap. More details would be appreciated.

[Rolf]

Nicely done. Did you use the iron?

Yes, normal wood glue (water based) on both sides, wait to dry, and then using the iron. Verey easy.

A big thanks to Yggdrasil for the info.

Yes, right! ......... No actually it is real American walnut.

Sorry about the 4242... the 2 is so damn close to the 3.

Hi Rolf,

Well done ! Chapeau ! I have seen that veneer before with a friend of mine who's a cabinet-maker. That veneer is pretty expensive but easier to handle. I intend to do the same with my black Tolex Vinyl covered JBL 4312 B MK II Control Monitors. Did you remove the original covering ?
Do you have the recipe of the original "JBL"cabinet-oil ?

Quoting a JBL-heritage member:

Reoiling Walnut Cabinets

Today I dropped by the local hardware store and picked up some boiled linseed oil and pure gum terpentine, mixed it 1/4 terpentine, 3/4 linseed oil and applied it to my L300 cabinets with a piece of cloth from an old black cotton t shirt. After letting the mixture sit for about a half hour I wiped it off with a clean/dry piece of black cotton t shirt. This is the same mixture JBL used to oil the cabinets at the factory and it was noted in the older owners manuals re care of the cabinet finish. I'll let it sit overnight and add another coat in the morning but so far the cabinets look excellent with a very low luster and the grain pattern highlighted. If I remember correctly it was recommended to do the simple process at least once a year to keep the walnut veneer looking its best. The cost of the boiled linseed oil and pure gum terpentine was about $12 plus tax and should be sufficent for a lifetime of reoiling.

Lots of success,

Hi Rolf,

Did you remove the original covering ?

The speakers was in studio grey, later painted black. I just sand it down a bit. On the front edges I had to sand it down totally to get a strong fix.

Do you have the recipe of the original "JBL"cabinet-oil ?

No, I use "LIBERON" finishing oil, and the result is about the same as original. Maybe a little lighter.

Hi.

Here are some new pics after the attachment of the front lists. Next step is to make the grills. Anybody have good ideas what to do to make them look fine? The frames are already made.

Contact Zilch for the material he's got

Very nice. When I did my 4507s, I removed the components. 40 LBS less to deal with.
How did you get the veneer so flat while gluing? The moisture in the glue will curl it up. Spraying water on the opposite side will offset the glue.
You did a great job!
