souri's blanks

[emidisc]

A while back a friend gave me a number of souri's blanks to try
anyway finaly got round to testing them started with a steel MSS stylus
gently heated the disc with 40w bulb prior to cutting,
I was really pleased with the cut very little surface noise and good quality
reproduction - far better than any of the previous none acetate discs Iv'e tried,
but am I correct in saying that souri does not sell blanks to none vinylrecorder owners???

What is a steel MSS stylus?

MSS was a british disk cutting lathe and lacquer manufacturer. There is a thread somewhere with pictures of a MSS lathe. Seems like they had a complete product line with everything needed for record cutting.

Steel styli used to be popular, probably because in those days the fidelity was limited rather by the rest of the cutting head than the stylus material.

I've made a few cuts with steel styli (normal groove), and must say that it sounds surprisingly good.

@emidisc: do you cut normal groove? is the cutterhead also MSS?

[emidisc]

forgive me when you ask "do you cut normal groove?" not sure I understand?

my lathe & cutterhead is BSR circa 1947
recently obtained a replacement cutterhead (like new!)
with it came 12 unused MSS steel stylus - they cut very well,

is it possible to heat a steel stylus I understand nichrome cannot be wound
directly onto stylus??????

Yes I'm in that too , can apply heat on a steel stylus ? and how do it ? , but represents that MSS steel stylus is for do cutting or embossing ? and most important , heat a stylus for emboss is senseless ?

I'm embossing PVC with a Presto 1C on a 6N overhead , and the results are very very near of be really good , definitively the angle in the Peter King's video was be the key. with the 1C not so extreme angle , but much better results in that way.

Mani, are you embossing with a steel or sapphire? And how did you get the head leaned back that far on a 6n and still make contact with the record?

Hi,

Back when I was experimenting with making my own steel cutting styli, I was able to wrap nichrome wire around the steel shank and get it to heat up quite well.

You would not expect it to work for obvious reasons, but I got decent results this way. I was using Duco cement to attach the heating coil to the shank. This is a nitrocellulose based cement and I chose it since its inexpensive, drys quickly, is easy to remove, and is made of the same basic material as the blanks I was cutting. I would run up the heater current to the point that the cement would start to smoke a bit. I think this had the effect of forming an insulation barrier between coil and the shank. I would say to give it a try. I can't see that there is any harm.

I'm not sure I see an advantage to using heat when embossing, but it might be interesting to experiment. You might just stumble on to some benefits. Perhaps it would allow you to emobss a deeper groove without using much downard force. When you increase the force, you reach a point where you stop embossing and start cutting or tearing into the base material (not good). That seems to set the limit on embossing depth.
