The Secret Society of Lathe Trolls

As you can see at the attachment photo the seller does not ship it to Greece
if you sell a lathe local pickup is your first choice.

This lathe have serial number 18
at 90% i'm sure the lathe was stored at Columbia records here in Athens.
watch the videos to understand what happens when Columbia closed in 1991

Hi Gus, do you think this is contributed mostly by the bearing, or by the platter surface? You can try measuring at the spindle itself to see if this is wobbeling or if it is standing still. Hi Jesus,i have measured the spindle and did not noticed any wobble. But i've noticed a very strange phenome...

That is true but for motor bearings vs pulley vs idler, i didn't heard in the past that the centre bearing tends to wear out from the pressure of the rim drive rollers.

Hi everybody, I use new turntable bearing. Finally my Problem went away! Groove is stable.I'm so happy!!! Thank you very much who advice me!! Marcy Be careful i think souri didn't calculate his ( precision = i'm not sure) platter vs Technics spindle/bearing That means in the near future maybe will ...

As the owner manual writes the overhead pitch work through turntable's worm and gear at 98,118,141,161 lines per inch what i did was to remove the gears and to install direct at feed screw a stepper motor controlled at different speeds electronically via arduino as you can see it works pretty well :...

this is no good thing, i recommend to try with a new spindle.

Stepper motor with 4.6 Kg/cm torque drives the feedscrew of my Fairchild overhead take a look. fIpMBBHUHsY Also take a look at Norman's Field page he modified his MSS Lathe with stepper motor too BUT controlled by a very famous 555 timer IC :wink: http://www.normanfield.com/homemade78rpmrecords.htm

With the help of member markrob i've found the correct transformer for my amplifier and cutterhead. Connect the 100V, 15 watt tap to the head which will be a pretty close match to a 500 ohm head. You can calculate the secondary impedance from R = (V squared) / power. In this case: 10000 /15 watts = ...

Suitable amp for Fairchild cutterhead is UNIT 540 AMPLIFIER - EQUALIZER very rare and very expensive these days. Fairchild Unit 540 eq-amp.jpg Second option was to build my own tube amp with 500ohm output or to find a P.A. amp with 100volt output. Third option was an amplifier and reversed 100 volt ...
