K3LA Train horns? Discs?

[Lilpooh]

Can someone tell me the OD size of the discs that are on the inside of the housings? Also, where is the best price to get replacement discs? I've seen them online for $45, is there a cheaper place?
Thanks, Rich

Bump, someone's gotta have old diaphragm disc's laying around that they can get me a OD measurement. I wanna start making the housings this week end.

Nathans' right?? I probably won't be of much help but when I get back to Wisconsin next weekend I can measure mine. I'm in Ks right now taking a refinery silo to Katy, Tx so it's pretty slow goin. Let me know if I can help.

That would be great, yes the Nathan K series. I found alot of info on the net, and have made horns using PVC, but the PVC horns aren't loud enough. On another site, one of the members gave me the size of the disc housings, which were 6", so I'm guessing the discs are 5".

Right now I have one housing machined, and have been experimenting with the material of the discs. So far the best results are with .010" thick spring steel. I also had to experiment with the disc gasket, and found that a PC mouse pad seals the best.

If the disc for the Nathan's are 5", then I'll buy the disc kit. If the disc's are smaller than that I'll have to machine a new housing!!

If disc are 5", then I'll go ahead and spend the money for the discs. Right now I got the horn sounding pretty loud. According to the info I found online, the disc's are made out of stainless, and most likely they are harden.

Hey Lilpooh,

I got those measurements for ya. The disk is dead on at 5", there's two of them in each assembly that sandwich a silicone ring that measures 5" O.D.X4" I.D.X 1/8" thick. They sure look like they could be spring steel but then again how thin they are its hard to tell the difference between SS and spring.

Hope this helps you out
