stick-struck drums
Just took look at the SPLs of a stick-struck snare drum versus hit with brush. Man, it's a full pegger at ear-distance with all but the most flaccid of velocities. I've looked online and seen consensus that no drummer should play using sticks unless wearing musician's ear plugs or closed-back headph...

Re: Increased depth
So, as long as they don't cut the heat test/sound check all the way to the mould gate disc diameter, but, instead, there invoke lifting, repositioning to 11.5" (dd) and redropping with starting spiral (aka Lead In), using increased depth is optional (by today's record industry "standards") but, usin...

Re: Ortofon Network
I read that [H] is only 1/20 as combustible as automobile engine petrol. Also, it's lighter than air, so it tends quickly to rise to the ceiling. I reckon with proper ventilation, as well as an eaves which is constructed in a way to be easily blown clear of the room. might make acceptable working en...

Re: 100% correct stylus heating
Clearly there's less friction at the inner radii which are passing land more slowly under the stylus and this makes the heated cut a little colder at the end of the side if heater coil heat hasn't built up during the cutting of a long side (a big IF...). I think I read that the loss at 8 kHz by the ...

Uh, it's directed at the thread; not at anyone in particular, Chip. ("bwooah~!") So, I agree, let's make it called Making Stampers and Using Presses. That's nice and New Age pacifist while being wholly accurate from the perspective of the broader industry of galvanoplasty. ("bwooah~! #20, I mean, 2)...

Re: Best stylus shape for playback of acetates?
]I'd think that the mass spring characteristics of the cantilever would have a great influence over the appropriate tracking force. Indeed. However, the AES literature already states that 1,25 grams is the ideal for the elliptical. To mate such a jewel to a cartridge with spring characteristics tha...

Re: Best stylus shape for playback of acetates?
...you had me at "...electron microscope."

How slowly the tape can be shuttled ends up being the decisive f...

Re: 100% correct stylus heating
I have been surprised the first time I saw that on the vms 80 , and I did some test of noise. increasing the current with the diameter gives less noise. the heating has not so much effect at the begening of a side , you can cut with nearly no heating and you won t have so much noise , at more than ...

Re: Depth half width q
Reading ahead, page N-1 seems to present more confusion to us. This is the Appendix N in Basic Disc Mastering, which is on the Scully auto variable depth controller from 1960 (DC-601). "The total width change available from the depth unit is approximately .002"." Does this mean that the depth can on...

Re: 100% correct stylus heating
Paul is right. The heat should be set by ear at the outside, and, if anything, the current should only be slightly reduced during the side (not increased), since the heat is building on its own through imperfect dissipation. Watch for horniness. If the heat was sufficient fully to be pulled during t...

I can't say why he called. Perhaps he wanted a better Turing test. I can say that he were weird. Odd cadence and accent - as if he were acting, poorly. He called to point out the error in the Basic Disc Mastering book and wanted to know if it was merely an error in compending, or an error in the ori...

Re: Depth half width q
Well, I hadn't thought of it as a deliberate mis-nomer. I reckon that the 1,8 mil figure was meant to be groove depth and perhaps not even for the new micro-groove tip? "001,8 mils" looks a lot more like the defacto depth created by a 110-degree included angle when the GPI, just nearly touching, is ...

Cool thread. (; Didn't know about the need for room humidifier, Concrete. Hah. Here's a face palm for your Sunday, I set up my lathe in my tape (cold dry) storage room. Not moving the lathe.

Re: Sticky residue on Apollo Dubs
Please post affected batch codes. We're possibly seeing this, but there results are only partly similar. Mostly the right heat and position can be found. But it seemed to used to be more effortless.

Oy, Got a call from this weirdo who said be mindful page M-5 of the new compendium of Basic Disc Mastering articles and industry documents has a strange chart on Scully's 1969 Width/GPI chart for unmodulated grooves nearly (not) touching. It's showing the test cut groove widths that correspond to th...
