Cutting Lathe using super optioned SL1200Mk5

[Mike_New]

Hi Folks,
I have recently been requested/commisioned to upgrade a MK5 for the purposes of recording on mastering laquer and direct to vynal.
This so far has been defined as a total set of my upgrades and including the Paul Haynes Power Supply.

The MK5 will be bolted to a rigid stand (not yet speced out) and the cutting head will travel across the platter on a beam.
The client will be flying in to Australia to review my progress and later for final tests.

This is somewhat of an exciting project for me and does I guess show a good deal of confidence in my upgrades and Paul's PS.

The client is a Radio Station manager

Now this is where I would like some help or advice! Has anyone come across this application of a SL1200? and what are the possible known unknowns that I do not know!!

Wow Mike, that is very interesting. Does the 1200 DD motor have enough torque for cutting applications? What cutting head is it?

[Mike_New]

The SL1200 motor should have enough torque for the cutting action as I understand it actually requires very little effort to cut the masters.
I do not have any data on the cutting head and beam system, except that I believe it is made in Germany.

Well done Mike- that is interesting, keep us informed:)

Vinylium make a relatively affordable dubplate cutter which I've seen attached to a 1210 so it has been done before. I've no idea how good this is though. It isn't exactly a Westrex or Neumann!

For all you future dub plate cutters.:gig:

....but it's got a rubber band.

I was at one point interested in make a cutting lathe and after having a demo and a chatting to the designer (the man in the last photo) about using a SL 1210.

He said that the standard SL 1210 is ok if you cut you tracks at low level but for high level cuts ( +12 to 18 db) you will need more torque and more mass on the platter.

[MartinT]

Thought it might not have enough torque for high level cuts. Driving an SL-1210 with a belt . . . <shudder>

[Artifolk]

Did anyone notice the feet on the Techy.. They don't look like Isonoe's, any ideas?

[Mike_New]

It looks like he is using a platter simmilar to my alluminium one, what does the external belt do??

The additional platter is a machine grade stainless steel which weighs about 4kg.

The belt drive stepper motor was added to aid the SL1210 motor under high level cutting.
I can't remember the exact figure he quoted for the cutting head but I think it was about 250-350 grams!

He suggested that a SP10 Mk3 was up to the task if you could find one and the additional motor won’t be required.

Hi Sharif,
What you say makes sense. I am intending to use my Copper Bonded Alluminium Platter. Are you saying that the cutter head has a downward force of
250-350 grams? cos this is my main concern, that the whole cutting action is supported on a relatively small diameter taper especially out at the 300mm diameter of the recording. This would represent a large force tending to tilt the platter.
