Using cnc router for a custom made lathe
Hi all! Like many of you I have been obsessed with vinyl for quite a while and the idea of making my own has been in my head for a long time. First of all, I wanted to say thank you all for all of the fascinating information on this forum. Reading all of the posts on here is very encouraging. So, I've been playing with an idea of building a lathe using a cnc engraving router. Has anyone done this before? Thoughts?
Something like this...

Hi,
If you are looking at using that to cut blanks, that should work fine. If you expect to cut audio, I'd say no. What do you have in mind?

Hi Mark, thanks for your reply. I was thinking of mounting the CNC on top of a turntable and using it as a carrier for a cutter head.

Hi,
That should work. But it seems like overkill. You only need to move in one direction (maybe two if you count head drop). Also, you need to be sure that if you go with a stepper drive that it does not modulate the grovve due to stepping torque cogging. That will for sure require 16X or better microstepping or as some have done, pure sinewave drive.

Would using a CNC router let you use G-Code for vari groove automation. There are lots of off the shelf solutions for that. Is G-Code up to the task?

Re: Using cnc router for a custom made lathe
markrob, the idea was t remove the y axis (the table platform) and only using the x/y movement for tracking and head drop. The other thing is what gold mentioned - using the G-Code to control movement speed and do lead in/out/lock grooves. But I am not sure how stable the construction would be and wanted to see if anyone has done it before.
Re: Using cnc router for a custom made lathe
Idea is good, but CNC machines will have a lot of mechanical noise when it's moving. I mean, A LOT. So using it for cutting will probably destroy your stylus fast and you will have a lot of bg noise on the records.
Re: Using cnc router for a custom made lathe
I've read somewhere here that stepper motors used in CNC machines are not good for cutting records. I think Flo Kaufman wrote this but can't find it
