For all cutters:

I thought i post this first on the relevant forums before it goes to ebay.

for sale is a scully lathe in need of restauration. as you can see in the pix there is a lot of stuff that comes with it like:
- amps
- controlers
- the lathe itself
etc.

the lathe is not in working condition and needs to be restored by someone knowledgeable. sorry no head included.

here are some more pix:

all serious offers will be considered. all parts will be sold as a complete package.
the lathe has to be picked up in austria, or shipping has to be arranged.

cheers mex

I Have a Westrex 3D-II stereo head for sale, together with some other heads, mono and stereo.

I see the knob that set what lpi pitch was to be used, went from 105 to 600 lpi. Must've been for 16 RPM records for the blind. It's also the usually quoted range of 70 to 400 lpi on such machines, multiplied by 1.5 times.

Of the Scullys, I'd say I prefer those with this feature on it. It has lead-in / spread / catch groove spacings of 7.625, 14.729167 (or 15.583333) and 32.3125 lpi (only two spacings actually used - 7.625 / 14.729167 or 7.625 / 32.3125 or 14.729167 [or 15.583333] / 32.3125), and lead-outs which, based on lathe make, are as follows (slow moving first, fast moving second, all approximate figures in lpi):
- 4.625 / 2.3
- 4.165 / 2.1425 (or 2.105)
- 3.915 / 2.04
- 3.835 / 1.98
- 3.6875 / 1.92
- 3.4825 / 1.86 (or 1.83)

But the 1.5 times figure was also used in earlier models of this make from the 1930's, with a gear box as in the picture shown here. Such models had increments of 8 at the outset for one set of lpi, and 12 for another. On one such lathe, used by Columbia in New York since at least 1939, and used to cut most of their 45's from 1951 to its retirement in 1966, here are the spacings:
- 88, 96, 104, 112, 120, 128, 136, 150, 164, 177.33, 190.67, 204
- 132, 144, 156, 168, 180, 192, 204, 225, 246, 266, 286, 306
The second set is the first, multiplied by 1.5. The first set had "groupings" of 20 / inch; the second, 30 / inch. This type lathe, as used by Columbia, had a "chickem" or "bookem" type sound if you listen very carefully (especially with earphones) at the point the lead-out is being cut. And on such earlier lathes, the lead-in and lead-out spacing move the same velocity regardless of speed, so it's closer spaced on 45's than LP's; and the velocity is varied based on whether the first or second set of lpi is used.
