A pair of 075 horns and phase plugs finished today.
Very good work. This parts are not polished yet, only machined !
They are copied from an original 075 driver with center holes for the dia center pins.

This parts are build on a 37 year old machine which works very well today.
There is no loss in the slide carriage (?) of this old machine.
The contour of horn and phase plug is gaged (?) (abtasten, abfahren) by an
hydraulically controlled machine part. You have to build a steel blade contour of the horn before.

He says brass, man you gonna polish those every day down here! Remember the navy spec brass railing I had in the old house? Have fun, he told me!

But they look so nice!

My father also said, if you coat them with the " Right " clearcoat you wont have any problems!

I spent a lot of time with "Brasso" cleaning the brass pipes onboard the ship. It was a daily job to keep up with corrosion out in the Pacific ocean!

They do look "COOL" though!

Personally I love the look of well machined brass. If you polish them they will look more glitzy, but loose that beautiful machined look.

As for protection against oxidation, I prefer wax. It is less effective than a polyurethane or a catalyzed clear coat, but they seem to all eventually fail. Wax is easily polished off and reapplied. The other clear coats are a real bear to strip when the time comes.

Yes Mr. Widget,

I will try wax too (for cars). Idon`t think that a clear film paint is good !!
The next parts i will try to polish them with scottsbritsh (?) and after that i polish (save) them with wax.

you could always get them done with a clear powder coating. then you would almost never have to worry about corrosion on them

Powder coating ??
What is this ?

Mr. Widget
07-22-2005, 12:33 PM
Powder coating is a dry powder epoxy that is electro-statically applied to the metal and then melted on in an oven.

I would avoid it for two reasons. First, it will five the metal a dipped in plastic look. Second, it will eventually still let corrosion in and then you have to strip off the epoxy.

Yes Beardsley,

I have the chance to plate them with Tin (Titannitrid) which looks like gold.
This is a very hard surface you canīt remove without ....

paragon, the Brass job looks nice. It sounds like you are describing a "Tracer Lathe". Just because a machine is old doesn't mean it's no longer precise, as your "New Horns" verify. You must have Simichrome Polish over there, it is made in Der Fasser Land...I'ts nice for brass AFTER the finish is smooth. The White Scotch-Brite is the finest, as far as I know. The next time you're at a festival, inbetween White Radishes and Weizenbier, ask the Tuba player what he uses to keep it nice....

Wonderful craftsmanship...just beautiful, Eckhard. It would be cool to see a 2405/077 with brass phase plug too....or gold-tone anyway.

Ah, Titanium Nitride! That's something I hadn't thought of, but what a great idea! :blink: If it works on drill bits, it ought to work great on these.......nice parts by the way.

Eastman products has a product called Nylac that would coat these and keep them from oxadizing. Ppolish less, enjoy more.

Silly question.... If you are going to plate them, why not plate the original aluminum parts?

These parts are not cheap !!!! Price of a pair ( 2 horns and 2 phaseplugs ) is
about 540 USD + shipping and the parts are not polished:biting: . You can see pics of not polished parts above. Shipping weight is about 3-4 Kg.
Yes, thatīs it. This is 190 USD cheaper than the japanese parts.
Maybe to build them in series they are cheaper. And you can polish them yourself, if you want. To polish them maybe take 2-3 hours.

Parts Express will sell you a pair (2) of brand new 2402s with magnets, diaphragms, the whole deal for about $518 plus shipping... :blink:

Are you thinking that brass will somehow sound better? ...or are you after the cool factor?
