Uni-Protractor Set tonearm alignment

Genesis168,
+++++"So Ford made the first car."++++++

Ford did NOT make the first car. All Ford did was start mass production.....

All this is very interesting. Personally, I wouldn't pay that much for a protractor. And with all do respect to DT and everyone else. It doesn't really matter how precise the instrument is. Even though the more precise the better. It still comes down to a persons ability to see where the stylus sits. And their ability to physically move it in micro increments. Then, tighten everything down and not move it while doing so. Just MHO.

DT, it does appear you have designed a very nice tool.

04rdking, not a problem if you think it is not worth that coin. Some are happy with the protractor they printed out from vinyl engine. Some spend $20. Some might prefer to spend $200. So whats the problem here? What I have a problem is that there is no absolute. Raul is preaching absolutes. That s my problem. We have choices. If everything has absolutes, we will be all listening to the same system.

Dear Genesis168, couldn't agree more with your last post - you recall the phrase by Obi-Wan Kenobi in Star Wars III - Revenge of the Sith, just before the final duel starts ?
"Only a Sith deals in absolutes" .........;-) ....
Cheers,
D.

Genesis,
I totally agree. We all have choices. I chose a $50 arc protractor designed for my Schick arm. And it gives me the choice of L, B or S geometries. With the Koetsu, it is very difficult to see the inner null point because the body is so low, and the stylus so far back from the front of the cart. As I said, whatever protractor one chooses to use, it still boils down to eyesight and steady hands.

Now, if say DT, or any other member that has one, were to offer to let me try his, would I say no? No, I wouldn't. Heck, I might even be willing to pay a small rental fee.......

Dear Genesis168: +++++ " What I have a problem is that there is no absolute. Raul is preaching absolutes. That s my problem. We have choices. " +++++

in mathematics and geometry is part of it there are no place for " subjective ", in our world: 2+2 always gives 4 and this is what I'm talking about. That you or any one want or would like that 2+2 could be 6 has no sense in the whole cartridge/tonearm set up geometry subject.

For you can understand what I posted in this thread you need to read and learn on the white papers by Graeme F. Dennes that you can find out in the net or download here:
www.vinylengine.com/phpBB2/viewtopic.php?t=4854

Read it one and again till you fully understand what you read and then come back on that " absolute " subject because right now ( with all respect ) seems to me that you don't have any idea on the real subject.

For we can have a productive discussion at least we have to be in the same " channel " because if I'm talking of apples and you don't have any idea what's an apple how can we agree on nothing?.

Do it a favor, please read those Dennes white papers and I'm sure that the " ligth " will shine for you or any one that read it. As a plus you will learn that the idea DT try to " sale " here about " especial " tonearm set up due to very " especial " tonearm geometry is totally false. Please remember that you need only three known parameters to make a cartridge/tonearm set up: effective length, overhang and offset angle: nothing more.

Regards and enjoy the music,
Raul.
