Perhaps of interest to some here: Stamper Discs are proud to present a series of 3 short films giving a behind the scenes looks at one of the most overlooked aspects of the vinyl record manufacturing process. Titled ‘The Making Of A Stamper’, ‘Troubleshooting The Test Pressing’ and ‘Motived By Music...

Perhaps of interest to those in this thread.

Hi J, assuming you're still popping up at the end of June will make sure you get one then.

All emailed

No problem, I've sent off for a small batch to be made. I'll message you all once they're done.

Would be happy to do a small run if there was enough interest for 4 or 5...

Thought a couple of people here might appreciate this fun little adaptation to a Technics deck for the on/off switch so that it can now accommodate 14" discs without the need for a huge stack of slip mats... Too much time on my hands evidently...

Perfect! Cheers for that.

Cheers Misjah, had hoped it might be a widely known figure but will check with TKO.

For no other reason than curiosity, does anyone have a spec for the micron thickness of the copper layer on a DMM blank.

Apologies if this has been posted before, I had a quick skim and couldn't find anything.

Curious what other people use. I use these, I do however dull the end a bit with some sandpaper before using them though so as they're not too scratchy and personally I can't distinguish from anyone elses scribing on lacquers. https://www.amazon.co.uk/QWORK-Tungsten-Engraving-Retractable-Ceramics/dp...

Cheap option is the Audio Technica ATLP5 - it will fit a 14" with no modification at all. If you shop around the vintage hifi world there are hundreds of transcription turntables that will accommodate a 14" disc without any modification too, it just might involve traipsing around a few hi-fi dealers...

The sour smell you mentioned is Chlorine gas. Not very good for you. The texture, softness and smell all mean that the PVC is burning. Perhaps your thermometer is broken? I would suggest getting a meat thermometer that you can stick in the middle of the puck. They're always handy to have around the ...

Stamper Discs from the UK will be in attendance! Looking forward to it.

It's common practice for some plants to grow a very thin nickel film for storage to protect for this very reason.

The "anti-slip ring" (or the so-called 'necklace') on 7" records during the heyday of record stackers was created by the stamper forming tool These ridges are therefore not on the record pressing mould - just the stampers. Once their used was phased out, you will see a raised ring around the outer ...

HI I was wondering if anyone had any photos or more info on the molds that would have had gripper ridges on them. (The bumps around the outside of labels on 45s to stop them slipping on stackable record players) Purely curious as I've never seen any stock footage or anything on them. 20200503_163326...

Admittedly I have a vested interest in nickel stampers, but it does seem a bit crazy to me based on this interview (things might have changed though) https://www.youtube.com/watch?v=CYZtTdiltTg -Designed for pressing 10,000 + records (most orders are under 500 though) -Won’t be any “HD” sound benefi...

Not sure about those ones but this might be of interest. And I think one came up for sale on German ebay a while ago. "Automatic Tick Registration Machine" by Polygram
