Columbia 710 Horn Construction.

[EarlH]

This machine was in pretty tough shape so I junked it out last week and though maybe you guys would like to see how the horn is construction on one of these things. They are completely different than Victor and there are a lot of joints to seal on one of these things. They used some sort of hard black wax and it was all falling off the joints. The people that I got it from dropped it face down out of their pickup and that might have knocked some of that loose also! These things are pretty heavy for no bigger than they are.

Finally! I always wondered how these were shaped! I've seen them from behind and wondered how the curve worked. Looks good, but yes, quite a bit of pieces/joints to make it heavy.

Thanks for posting. I have a Columbia Viva Tonal 800, and its horn is similar, but larger. Recall that Columbia did not license the Western Electric designed phonograph that Victor did (e.g., Orthophonic). The Columbia horn is a homegrown affair. My Columbia 800 sounds pretty good since I resealed all the leaking joints, but it is not as good as a Credenza, plus it is heavier and bulkier. It's a nice machine to have in a collection from a historical standpoint, however.

Many thanks for posting this! It shows that Columbia opted to install a simple divider in the chamber to narrow the taper, instead of trying to fold it.

The Inventor is identified as Frank C Hinckley. In fact, I spotted the patent for the horn:

I posted this before, but here's the patent information about the large horn -- https://patents.google.com/patent/US175 ... y:19250101

Wow! Cool! I used something similar for the decor of my house when I built it myself. At first, I needed to understand how much the construction would cost me. I didn't have any money. I don't know how to save money. It means only a loan. The maximum loan that I could master is $ 20,000, and then if for five or six years. After studying the prices of building materials and considering that we will build on our own (usually half of the cost is work), I realized that it is quite possible to meet this amount. We decided to use high-quality products from Pete Suen and we really liked it. I hope that my experience of helping others will be useful for you and the use of this construction will also be useful!

Is it hard to build this?

It all depends: Are you a good woodworker? If so, then NO... If not, then YES...
