Mint Protractor for the Classic Toneram 10.5i-SE

Have your read your response to those who politely responded to you.

Brf, those numbers are definitely incorrect. I measured the S2P distance and it's precisely 262 mm. This is what VPI used to have posted on their website a few years ago before they took it down. It is definitely not 258 mm

Also, the effective length is not 273 mm

Why do you assume that the info Mike gave you is correct? Get a ruler and measure the S2P distance on your Classic and see what you get.

Get a ruler and measure the S2P distance on your Classic and see what you get. As I said, if the distance is from the sharp pivot point to the center of the spindle, as it should be, it is dead on 262 mm on my Classic.

I get an effective length of 277, which again confirms that the S2P distance is 262, not 258 mm. I can't argue with the ruler.

A basic understanding of geometry will tell you that a 4mm difference in the S2P distance cannot be achieved between a level and non level tone arm (unless we are talking about the VTA tower being adjusted upwards by inches and not mm).

You asked a question and then proceeded to argue and discount the responses from seasoned Audiogon members who know a few things about VPI tables. I don’t have a problem with questions, but you always answered in the definitive when in fact you were wrong.

Testpilot,

You took select quotes from several of my posts out of context to prove something that I'm not quite sure is relevant to anything except to fuel some sort of a forum feud. I guess you forgot to quote from the posts where I admitted I was embarrassed by insisting on my wrong position, and openly thanked posters personally for their input. If Brf felt offended by me calling into question information he got from VPI, I'm sure he was more than capable of expressing himself, and he does not need you to advocate for him.

Look, it's a hobby forum where members come to get information, clarify information, exchange information, ideas, and express their, sometimes strong, opinions. In my opinion this is precisely what occurred in this thread and no lines were crossed, and apparently nobody except you had their sensitivities offended, which is rather absurd considering you were not even a part of it until now. I sincerely admitted I was wrong, and sincerely thanked all for their feedback and great info, including personal thanks. What else do you want me to do? If you give me your address, perhaps I can come over and give you a foot massage. Would that make you happy? Ridiculous.

So, what did we learn?

1) Classic JMW S2P distance is 258mm,
2) Overhang is 15mm,
3) Effective length is 273mm
4) Info on VE is wrong

Are you really so obtuse? Or do you have reading comprehension problems?

1) Classic JMW also came with an S2P of 262 mm so my belief was not baseless or impossible.
2) I did not argue about overhang.
3) Effective length is 273 mm for S2P of 258 mm, but would be different for 262 mm.
4) The info on VE was not wrong when the article came out, and is still correct with respect to some VPI tonearms.

What I don't get is the purpose of you continuing to post in an otherwise dead thread and going after me. What are you trying to accomplish? Actually, I don't even care at this point. You made your point; I made mine. Good day to you, sir.

There was a question brought up about the Effective Mass of the VPI tonearm. I did receive information directly from VPI that the effective mass of the Classic 3 tonearm is 11.1 grams. That arm is called the JMW-Classic 3 damped stainless steel tonearm. At the time I received this information I tested it. I computed the resonant frequency with the calculator based on my tonearm, cartridge compliance and weight. I then then tested it with a test record and the frequencies came out very similar. I therefore convinced myself that the effective mass information for the classic 3 tonearm was correct.
