The Secret Society of Lathe Trolls

Thanks Chris! Very interesting...!

I am only too aware of this. Any technical info?

I need some advice please. I need to know what in the galvanic process could cause a loss in top end. There is a pressing plant I use a lot which I and several other cutting engineers I know in the UK who have been getting occasional TPs back from the plant which sound very different to the test cut...

Are these the four on the left hand side J1 L1 and J2 L2?

thanks for that. Yes I cleaned the pot, which is now smooth as well as the connector, unfortunately the problem persists. I wonder if it is not an amp issue, where the amps are producing too much vertical signal? I am going to try and take the connector from the depth panel out of the equation and s...

Thanks Greg. Will try again in the morning and report.

thanks

I think the dash pot is fine. I did top it up with oil but to be honest this is only the second time I have had anything go wrong with this lathe in five years. My guess is that this has to be an electrical problem as a physical one would have more consistency in its error.

So I cleaned the pot. Needle movement is now smooth, although when I turn the lathe on the meter reads 70ma and then slowly comes back to 30ma...

I normally have it set around 40ma, not sure that makes a huge difference though right? when I move the pot even with the head up the needle movement is not smooth. It kind of jumps from one depth to another. once set however it seems pretty fixed. Will try some deoxit on them too. One question; out...

Hi Mark

Lift of is generally around 2 inches in length. the groove then goes back to normal. I was just about to do another cut with the servo from the head mech removed to see if that helps

Hi JJ, I did recently notice quite a lot of 'pumping' movement in the dept gauge, which I thought might be to do with my suction unit having worn down and the brushes sparking causing surges. I opened it up an indeed there were some small sparks (which I now think could be acetate dust). I then repl...

Both channels. It happens even if the track is mono.

Hi Guys, Frank from The Carvery here. I wonder if you can help. I am experiencing some strange issues on my VMS70. Essentially I am getting an apparently random lift of the stylus from the lacquer. At first I thought it was perhaps a phase issue as the audio I was cutting was shall we say 'experimen...

Can anyone supply me with around 100 white pvc/lexan blanks?

I need around 40 x 10" and 60 x 12"

thanks,

frank

The thing is that you already have a level meter in Cubase. I would just use the hardware VU meter to monitor the playback. For the first few months I would not cut anything over +3db and monitor the level of everything you are cutting whilst you are cutting. Get a really good pair of headphones, li...

Don't feel you have to use all the setup the way Souri lays it out. I used a mixer to control the levels but after a few years I started experimenting with creating my own RIAA correction in Protools and ditched the mixer as a level control. to me the signal chain was just way too long and going thr...

Anyone got an SP79 console kicking around? With so many lathes around there must be a big old graveyard full of them...

any leads?
