VPI 2nd Pivot for 3D

@moonglum : "  Van Den Hul states :

"But the most important thing is record wear. I measured temperatures using a thermistor with a thin wire around the tip. A conical tip went up to about 140 deg C, but my one was 60 deg. I would like to come down further, but this was the lowest possible value."

Hi Raul,
I agree it is confusing. I recall looking up the data at the time and the "248C" figure was known to me. I was somewhat surprised back then but given how easily vinyl warps next to central heating radiators I dismissed 248C as one possible value depending on composition and state i.e temperature at which it becomes fully liquid as opposed to becoming "soft"?

Clearly it does need to be a lower figure than 248C in order for the melting/reforming thesis to work?
Now you've got me wondering again. :)
I'll try to find the reference for you ;)

Best regards,
Bill

Dear Raul,
VDHs measurements of his own stylus seem to be defying the "natural order" of things by lowering the junction temperature to 60C. If true, one wonders if instead of vinyl reacting in a malleable way the stylus dislodges chunks which then fall into the groove causing further problems ;)
Of course 60C must presume perfect azimuth of his line contact(?) stylus. One would assume that misalignment would undoubtedly push the temp even higher than a perfectly aligned conical stylus's 140C, leaving the user in the same state as he was before :)

If VDH is successful with his low temp approach, the unit price of Last is going to rocket :D
Best regards
Bill

Dear @moonglum : Great facts/information. As I said exist formidable audio information all over the net and comes from experts.

Facts that can makes a paramount differences in each one of us ignorance levels, obviously all of us can improve our knowledge levels, skills and tools !!

Btw, @dodgealum , you own the Levinson/VPI tonearm and in the " you tube " link I posted here we can see a way " terrible earthwake " down there that if it's happening then exist something really wrong in that tonearm design.

Would you comment about?, appreciated.

Regards and enjoy the MUSIC NOT DISTORTIONS,
