Homemade Turntable





Introduction: Homemade Turntable

Homemade turntable for vinyl discs

Step 1: Introduction

I wanted to show them a turntable or turntable, as they want to call it, done by me in its entirety, and after much work I can say that the result exceeded my expectations.

Step 2: Cutting and Gluing

I started by buying mdf with the measures that I intended to make the tray and gluing

Step 3: Mashing

Total mashing to cover all imperfections and achieve a better finish

Step 4: Base Painting

Step 5: The Most Funny Step... : Painting

Step 6: Transmission

Placement of the pulley that will pull the plate. I used the pulley of a washing machine, I cut the part of the center and screwed the same to the plate, previously having marked with a compass the centered circumference.
The motor was extracted from a cassette player, has 4 pins, in two of which a potentiometer is connected to regulate the speed.
The strap, not getting the measure I needed, I cut a motorcycle camera and it was more than good.

Step 7: Tonearm

I used aluminum from a computer hard drive chassis, trimmed and polished

Step 8: Anti-skating System

Performing a basic anti-skating system. Mechanism that exerts a force contrary to that generated by the friction of the pick with the disc in the direction of the center, to allow a better reading of the groove of the vinyl disc

Step 9: Head

Made of wood for the cartridge

Step 10: Slowly Lower Mechanism

Step 11: Plate

To finish, I screwed to the plate some plates of lead that had at home, and to have a better view I placed a ribbon of copper in the edge of the plate:

Step 12: And... the Finished Homemade Turntable

Interesting. I'm wondering if it could be scaled up in size. I have a very old disk from probably the 1940's or so. I think it's something like 17 inches in diameter, maybe. It's a studio recording of my mother singing.

Presumably one of these: https://en.wikipedia.org/wiki/Transcription_disc

just to say that you opened my eyes mate and im gonna build it for sure :)
