The farmer and his plow - When I set out to build a record cutter

[farmersplow]

Hello Thomas,
It would be so much easier to guess with the arm mounted. Maybe too easy.. Anyway It is so nice work and usefull device.

May I ask how do you align diamond perpendicular to the groove? Do you have any marks on torque tube? I think about this topic for longer time and I have not yet found any precise solution. Or it is not clear to me..

Thank you and have a nice weekend

In principle, the alignment is quite simple. Almost every digital microscope has a crosshair. I use a digital microscope for mounting. I align the vertical line with the torsion tube and then align the diamond with the horizontal line. The only problem is keeping everything stable. That's why I made this device, because otherwise, setting it up was always a hassle.

Hey Thomas,

just took a listen at your sound examples and also did a small spectrum analysis quick&dirty with audacity.
I think de-essing and EQing would do wonders to these cuts - a lot of hf is missing and there is quite some dips in the 7k area.
At least in the american idiot when comparing to an original file.

We do EQ head corrections on all our machines - this would do wonders!

Spinnertown has written awesome instructions on their blog: "How to Map and EQ your Dynamic Cutterhead"

Hi Markus! Thanks for going to all this trouble. Working wonders sounds good! I think that, in addition to the usual EQ and de-esser, I should also adjust my feedback amplifier for the closed circuit a little.

The best thing to do is probably for me to pack up my stuff and come to your studio. Then you can take a look at my device and give me a few tips. I'm sure your experience can work wonders!

Best regards, Thomas

Thank you for an answer. That makes sense. I was overthinking over this topic. Your adjustment table looks really nice.
