You should contact one of the Antique Phonograph Societies in your area (preferably a maps chapter) and have a delegation of the members come out there. Our members are very knowledgable and will give a fair price for your items, and won't rip you off. They are collectors, not someone trying to low ball everything and then resell it for a huge profit. That way you avoid all the pretenders, and the rip off artists. Cash and carry, no advertising, no middle man, no commissions, just cash money, to take your precious stuff away where it will have a good home.

I asked for their take to be 20% and to put a reserve on the Hexaphone and Zonophone (worth thousands each). THe auctioneer, WOODBURY Auctions then declined...tells ya somethin! I realized later, that a "ringer" could come in and buy my multi-thousand machines for a few hundred and make off like a bandit if I didn't have a reserve! At first they asked for 35% + shipping costs, then went down to 25% with no charge for shipping. BUT, the mention of reserve suddenly turned them off. Just something to think about...RESERVES are very very important. They may be a put-off to some, but to the seller are critical and I'm very grateful for the replies I got here. Thanks folks, many thanks!!! Ger If anyone hears of an auction or buyer willing to take on my collection fairly, please let me know...still would like to clear it out (northwest CT)...for real this time. ;) Besides the Hex and Zono, there are 4 Edisons, a Vic, a Herbert (reproducer area incorrectly fixed), over a dozen horns including one extra large round brass, a bunch of parts, and over 500 records, about half of which look like decent blue Amberols (a couple of other odd ones too & some good wax). Everything is catalogued, including a few dozen fat flat records and a Diamond Disc head with diamond. I've had offers for the 2 main machines, but don't want to be cherry-picked. :) PS: For any one who finds some of the discussion here unrelated to their immediate situation, I suggest that rather than drop out totally, get put on daily digest...it works well for me, and I actually enjoy it.

Auction houses could make up to 45% on items ( 30% plus 15%) that make under $1000 There was an auction house near while I live (now defunct) where they would keep 50% commission on items you consign that total under $100. On top of the 50% the auction house also charged a 10% buyers premium. So the auction house makes more more on the item than the consignor does. Even though ebay has increased its fees they are still a viable alernative when selling items especially items that a easy to ship. -----Original Message----- From: Albert Menashe <almena...@gmail.com> To: Antique Phonograph List <phono-l@oldcrank.org> Sent: Mon, Jul 4, 2011 3:05 pm Subject: Re: [Phono-L] auction fees the auctions that I attend locally, charge the buyer 15%, the sales ommission are negotiable based on the type merchandise, and the potential mounts realized.

If you decide to sell just 1 or 10 the higher the commission rate. If you sell your whole collection like 50 or more then the commisson rate should be lower. I heard with some lucrative estates the rate may be as low as 20% or possibly lower.

If one does not realize the difficulty of Edison's inventions then one has not attempted to duplicate them. Has anyone ever played with a reproduction Bell telephone? Mine required shouting so loud that the person in the next room could hear me better through the wall than through the Bell telephone. It was Edison's carbon microphone that made it practical. As a retired Physicist and Physics teacher, I remember fondly of trying to make a tinfoil phonograph using the plans from the Edison Institute Ford Museum. Just the machine tool technology is impressive for today. Has anyone else on this list made a mandrel shaft and feedscrew for a Home, Triumph, or M class? I spent weeks last year doing just that. The 100 thread per inch buttress thread of the feedscrew is not easy to do. The tapered brass mandrel is an odd taper and I had a number of failures before I got one that was perfect. Only a few thousandths of an inch of slop in your taper attac hment and you are in trouble. My reproduction of the original tinfoil machine has never been completed because I became frustrated with my recording and playback styli. Just this week I am seeking the counsel of the most knowledgeable tinfoil expert in the world. When it comes to electric lighting, I have a San Francisco Market Street arc lamp in my collection. It draws 20 Amps at 80 Volts when struck, that's 1,600 Watts, and the carbon rods quickly burn out. Many years ago when teaching electrical circuits I had a setup to place a filament (a term coined by Edison as I recall) inside a bell jar that could be evacuated. Trust me, getting anything to last at incandescent temperatures is not easy, even today with all the knowledge we have. My students then had never given thought to the simple and ubiquitous light bulb. Usually they were enthralled by the warm glow coming from the bell jar. Many phonographic items were invented by Edison but he never got credit for them. Remember when the 'elliptical stylus' was introduced to play stereo LPs and was hailed as a great leap forward? What do you think the contact area of a 1902 Model C sapphire stylus is? Remember the switch from sapphire to diamond styli in the 1960s as playback equipment improved? That too was hailed.

Took a bit of research as there are contemporary reports that a buttress thread was used, but close inspection under a microscope clearly show the V form. If anyone is in need of a quality 3/16" or 1/4" half nut in steel with correct size machine screws, they are available at $20 and $24 respectively, including postage.

The depth of the thread is only 0.007" so the lathe setup is crucial.? I will have to check the later threads but the one I did had a buttress thread and the halfnut was likewise set.? It would make sense to have a buttress thread at 100 threads per inch with the 'strong' direction pushing the halfnut and carriage to the right.? At 100 tpi the thread height for any thread should be uncomfortably small. On yours was the thread a 'normal' V thread that was not directional?? What was the depth of thread? It is good to see you on the list.? I hope all is well with you.? My wife and I have a planned vacation down under.? Off list tell me what sights the locals would recommend?
