Subject: [Phono-L] auction fees
Thanks to all who gave info about auction fees. I asked for their take to be
20%
nd to put a reserve on the Hexaphone and Zonophone (worth thousands each). THe
uctioneer, WOODBURY Auctions then declined...tells ya somethin! I realized
ater, that a "ringer" could come in and buy my multi-thousand machines for a
ew 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
harge 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
ut-off to some, but to the seller are critical and I'm very grateful for the
eplies I got here.
Thanks folks, many thanks!!!
Ger
If anyone hears of an auction or buyer willing to take on my collection fairly,
lease let me know...still would like to clear it out (northwest CT)...for real
his time. ;)
Besides the Hex and Zono, there are 4 Edisons, a Vic, a Herbert (reproducer
area
ncorrectly fixed), over a dozen horns including one extra large round brass, a
unch of parts, and over 500 records, about half of which look like decent blue
mberols (a couple of other odd ones too & some good wax). Everything is
atalogued, including a few dozen fat flat records and a Diamond Disc head with
iamond. I've had offers for the 2 main machines, but don't want to be
herry-picked. :)
PS: For any one who finds some of the discussion here unrelated to their
mmediate situation, I suggest that rather than drop out totally, get put on
aily digest...it works well for me, and I actually enjoy it. Thanks for that
oo.

I am trying to locate a set of four "ball bearing type wheel casters" for an
arly VTLA. The part is a brass cup with a pressed on shoulder. The small end
f the cup slides up into the leg of the phonograph. In the bottom of one of the
ups is the remnant of a ball bearing ring. The open end of the cup has a
istinct crimp that I assume held the wheel. Obviously, the three parts I have
re missing the wheel assembly. I checked with George and Ron to no avail...

Were they only used on the VTLA?? I just parted out a VV-XIV and saved those
asters and related parts. In fact, they are still attached to the legs.
et me know if that would be of any use to you.

Good point Al about ebay. Auction houses could make up to 45% on items ( 30%
lus 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
otal under $100. On top of the 50% the auction house also charged a 10% buyers
remium. So the auction house makes more more on the item than the consignor
oes. Even though ebay has increased its fees they are still a viable alernative
when selling items especially items that a easy to ship.

he auctions that I attend locally, charge the buyer 15%, the sales
mmission are negotiable based on the type merchandise, and the potential
ounts realized. On smaller items (-1000) it is usually 30%. But it is
tally negotiable. A whole collection valued at 500k may go for as little
10% We know what the exhorbitant ebay fees are, but at least the buyer
esnt have to pay a commission.

Hi Ger:
Most auctions take about a 25 - 30% commission rate; however it also
depends on how many phonongraphs you are planning to sell at the auction
house. 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.

That's the history of innovation, no one EVER invents something in a vacuum, it
s all based on someone else's work. Altair and many others tried to come up
ith computers that were functional personal computers, the Apple ][ was the
irst practical home computer system, thus Altair is forgotten and Apple is the
argest technology company in the world. Same as the OTTO-cycle engine, many
ther engines were attempted but It was the first practical gas engine and thus
ikolas Otto gets the credit because his system worked.

f one does not realize the difficulty of Edison's inventions then one has
ot attempted to duplicate them. Has anyone ever played with a reproduction
ell telephone? Mine required shouting so loud that the person in the next
oom could hear me better through the wall than through the Bell telephone.
It was Edison's carbon microphone that made it practical.
s a retired Physicist and Physics teacher, I remember fondly of trying to
ake a tinfoil phonograph using the plans from the Edison Institute Ford
useum. Just the machine tool technology is impressive for today. Has anyone
lse on this list made a mandrel shaft and feedscrew for a Home, Triumph, or
class? I spent weeks last year doing just that. The 100 thread per inch
uttress thread of the feedscrew is not easy to do. The tapered brass
andrel 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
ment and you are in trouble. My reproduction of the original tinfoil machine
as never been completed because I became frustrated with my recording and
layback styli. Just this week I am seeking the counsel of the most
nowledgeable tinfoil expert in the world.
hen it comes to electric lighting, I have a San Francisco Market Street
rc lamp in my collection. It draws 20 Amps at 80 Volts when struck, that's
,600 Watts, and the carbon rods quickly burn out. Many years ago when
eaching 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,

Having just made a batch of half nuts for Homes and Triumphs I respectfully
ubmit that Home and Triumph leadscrews do not have a buttress thread, but
re 60 degree V threads.
Took a bit of research as there are contemporary reports that a buttress
hread was used, but close inspection under a microscope clearly show the V
orm.
If anyone is in need of a quality 3/16" or 1/4" half nut in steel with
orrect size machine screws, they are available at $20 and $24 respectively,
ncluding postage.
Hope I haven't stirred up the proverbial hornet's nest.

like the yoke assembly of the Model O reproducer with the tiny 0000-160 screw
hat goes into the stylus bar and holds on the washer with .019 arms that no one

G'day Mike:
Very interesting but the M feedscrew I had to duplicate was examined under an
ptical comparator and there was no doubt the thread of the original 1892 part
as a 45? buttress thread. The depth of the thread is only 0.007" so the lathe
etup is crucial. I will have to check the later threads but the one I did had
buttress thread and the halfnut was likewise set. It would make sense to have
buttress thread at 100 threads per inch with the 'strong' direction pushing
he halfnut and carriage to the right. At 100 tpi the thread height for any
hread should be uncomfortably small.
On yours was the thread a 'normal' V thread that was not directional? What was
he depth of thread?
It is good to see you on the list. I hope all is well with you. My wife and I
ave a planned vacation down under. Off list tell me what sights the locals
ould recommend?
Regards,
Al

Subject: [Phono-L] VTLA wheel casters
I am trying to locate a set of four "ball bearing type wheel casters" for
an
early VTLA. The part is a brass cup with a pressed on shoulder. The small
end of the cup slides up into the leg of the phonograph. In the bottom of
one of the cups is the remnant of a ball bearing ring. The open end of the
cup has a distinct crimp that I assume held the wheel. Obviously, the
three
parts I have are missing the wheel assembly. I checked with George and Ron
to no avail... Thanks

I must agree. I had to have a feedscrew rethreaded some years ago, and the
achinist told me he had to use an old lathe of his dad's to make the buttress
hread at the correct pitch.
an of worms hereby opened.

G'day Mike:
Very interesting but the M feedscrew I had to duplicate was examined under an
ptical comparator and there was no doubt the thread of the original 1892 part
as a 45? buttress thread.? The depth of the thread is only 0.007" so the lathe
etup is crucial.? I will have to check the later threads but the one I did had
buttress thread and the halfnut was likewise set.? It would make sense to have
buttress thread at 100 threads per inch with the 'strong' direction pushing
he halfnut and carriage to the right.? At 100 tpi the thread height for any
hread should be uncomfortably small.
On yours was the thread a 'normal' V thread that was not directional?? What was
he depth of thread?
It is good to see you on the list.? I hope all is well with you.? My wife and I
ave a planned vacation down under.? Off list tell me what sights the locals
ould recommend?
Regards,
Al
