Uni-Protractor Set tonearm alignment


Looks like Dertonarm has put his money where his mouth is and designed the ultimate universal alignment tractor.

Early days, It would be great to hear from someone who has used it and compared to Mint, Feikert etc.

Given its high price, it will need to justify its superiority against all others. It does look in another league compared to those other alignemt devices

I was always thinking about how to combine my measurement suggestion with the Dennesson and also the alignment by the Uni-Pro. Therefore only using one tool!!! For me the quest is over! You may see the result on my page (last image)

Dear Thuchan, dear Downunder, originally I designed the UNI-Protractor as a tonearm alignment instrument. Measuring P2S is a matter of tonearm set-up and should be done prior to any alignment (usually you have to drill a hole in an armboard and so the mounting distance is kind of "pre-determined" before starting any alignment).
That's why P2S-measuring wasn't include din it's design. I now realize, that including the stainless steel metric ruler kind of woke up the wolves....
In any case - I will come up with an add-on to enable precise P2S measurement with the UNI-Protractor soon. This will NOT need any alternation to be done to UNI-Protractor and will come with a precise manual and installation instruction.
It will be a 5-minute plug'n'play device.
However - please accept my initial concept, that in my - sometimes strange and weird - mind, P2S was not an integral feature nor request in an alignment instrument for tonearms.
I still think that P2S is a part of tonearm set-up.
But - I will address it due to "public demand" ...;^) ....
Cheers,
D.
Dear Dertonarm,
do you have a launching schedule in mind?

Best & Fun Only - Thuchan
Dear Thuchan, yes I have a schedule. The UNI-P2S will now come as a tool which can easily be incorporated with the UNI-Protractor (without any alternation !!) as well as stand alone as a precision mounting distance measurement instrument for it's own sake.
It will be introduced next week (i.e. first week of May ).
Cheers,
D.
Dertonarm,

I apologize but I think I may have missed something in your thread. Is the P2S for measuring the pivot-to-spindle distance or the pivot-to-stylus distance (overhang)? Could your device be used to measure either?

I am considering a separate dedicated arm pod for mounting an additional arm. I would think that your UNI-P2S, if pivot-to-spindle, would be indispensable for this purpose.

Keep up the good work. I'm beginning to wonder what other devices you have up your sleeve. All this for improving analog playback just as I read from Raul (in another analog thread) that he thinks the best digital can now compete and even surpass good analog. (Sorry if that is a bit controversial to introduce in this thread) I think it is all about tiny improvements in accuracy adding up to real sonic gains in either medium.
