The Secret Society of Lathe Trolls

oooooh ok! very cool lathe!
but yeah, it seems like a counterweight issue

ok yeah for sure - so are you cutting on the T560 with a TKV head? It took me adding extra weight to the head and adjusting the counterweight a lot to get it right. otherwise a regular 15g weight on the cutting needle will require too much dashpot, and lift the head/drop the head throughout the side...

this happened to me when the wires for the cutting head were getting caught on the lathe overhead, not allowing the head to advance freely

Like Dub Studio I'm going to assume a lot of details about your setup to give you lots of options: If it's the stock 1200 turntable, I'd guess it's a torque issue. If the blank is warped at all, it's that. Check for the head moving up and down when cutting, even slightly. Like DS said, excessive hea...

here's a great thread to get you started: https://www.lathetrolls.com/viewtopic.php?f=1&t=8894

yeah hrm! I haven't connected anything to the output of the meter except RCA cables that go to the cutting amp. you could just have a bad adapter? or something screwy with the monitor switcher? to figure out if the meter is working correctly, take it out of the signal chain. send a 1 khz tone direct...

After a very long break - during which I may have forgotten almost everything about the VR - I would now like to start cutting again. While looking for an answer to my question about the VU meter from IMG Stageline, I came across this discussion. When I connect the headphones to the output of the V...

huh! that's a real head scratcher.
I've had great conversations with Konstantin on Facebook messenger.

that's a tough one, especially on a budget! there are some experimenters out there who have done shellac records from moulds, usually re-inventing an old process with available materials. I can cut lathe cuts on plastic that are playable with fibre/bamboo needles, $75 each. www.audiogeography.com Ki...

yeah toss the mixer and the vinyl optimizer, do it in the box.
I go audio interface -> meter -> amp -> head

yeah they all do that. though the nylon threaded nut (halfnut? wholenut?) connecting the carriage to the feedscrew is permanently attached. vertical play is fine, but if you have left to right play or delays while using the handcrank, you'll need to tighten the tiny allen head screws that fix the n...

sounds awesome, congrats on the success!
curious what level you're cutting at?
I wonder if some of the frequency irregularities between each piece come from the overall volume level?
I can hear the drivers compressing and distorting a little differently on each sample

both are without a doubt VERY high quality systems. Just judging by aesthetics I would relate the Agnew system more closely with the Scully lathes - classic, heavy, hand built and modular. The Sillitoe I would relate closer to the Neumann lathes - state of the art, new tech, plug and play. they are ...

what's your setup like for inverse RIAA EQ?
that could very well be the culprit for missing high frequencies

wow, never heard anything like that! when one of my T560 heads was towards the ends of it's life, it developed a very wobbly/out of phase low end, and then eventually distorted low end that creeped up through the audio spectrum. This is certainly different. It acts more like a "blanket" over the who...

whoa, great work, looks awesome!

can't help directly - but I run two VRs from this player piano vac, it says "pulls 70" water vacuum" (not sure how that compares) and its 120V AC, 7.7amps. https://www.ebay.com/itm/292864311937?hash=item443012c281:g:tf0AAOSwljVgrCyJ&amdata=enc%3AAQAIAAAA0PdwuxjQyVGNP%2Fg1HrADlEBdhymM2iXmdrOPMMHx6PIb...

Sparks NV leads me to think they're attached to kunaki.com

following! I have a blown T560 head and would love to get it back up and going
