Feel Silly Asking This Question Alignment Parameters

@rauliruegas  @neonknight

At P2S 225 distance L¨fgren B gives you 17.53 that has no consequwences in your 17.5 desired overhang.

Your numbers are wrong.

The Agile manual from Origin Live sats -

Centre of mounting hole to centre of platter should be 222mm.

Based on that the correct numbers are as I posted above

Overhang for Baerwald A is 17.3mm - offset 22.99

Overhang for Baerwald B is 17.75 - offset 22.94

@neonknight

 

What is odd is the numbers do not match up. For Lofgren B as example the overhang is 16.8 mm, but the inner and outer nulls are slightly different. 57.4 and 114.8 and an offset angle of 22.4 

These numbers are nonsense.

The offset for Origin Live arms are designed is 23 degrees not 22.4.

The Agile manual which is available on the Origin Live website here

https://www.originlive.com/wp-content/uploads/2021/07/Agile-MK4-instructions.pdf

says the arm is designed for a pivot to spindle distance of 222.

I have posted for the second time the correct overhang for your arm.

Rauls numbers are not correct.

For the third time -

Origin live Agile ( standard 9.5" arm 239mm ) has a recommended pivot to spindle distance 222mm.

Overhang for Baerwald A is 17.3mm - offset 22.99

Overhang for Baerwald B is 17.75 - offset 22.94

If you can't follow this then I would suggest you purchase a cartridge with a conical or spherical stylus such as a Denon 103. Misalignment will be less of an issue with a conical or spherical stylus profile.

 

 

 

 

 

 

 

@rauliruegas It did not make sense to him because back in the day many more records were run right up to the label. Now that is a very rare occurrence. Modern records space out the grooves a little more and resort to two discs instead of one. The main reason for this is CDs accommodate much longer play times than records and artists have become accustomed to that extra space, thus the record version has to resort to two discs anyway, but even re-releases of old material are resorting to two discs when originally there was only one. Zappa records are a good example. 

You may love pivoted offset arms, but I do not. The problem is that there have not been any compromised tangential designs until recently. Both the Reed 5T and Schroder LT are brilliant designs that maintain tangency, have low horizontal effective mass and obviate the need for an antiskating device. You may want to talk about pivoted arms, an unfortunate, but necessary compromise, I would rather talk about these. Once the patent runs out on the Schroder LT there will be many more arms like it. The Reed is much more complicated and twice the price. 

@dover My apologies I missed your original post. Yes manual states 222mm and I do have the single point supplied alignment gauge. My preference is working with an arc protractor and wilL purchase one shortly. Thanks for the response. 

@dover : No it’s not wrong because OL says a margin of +,- 2mm. In the other side we can change those numbers with out any negative consequence because 225 means longer EL and les distortion.

 

I posted the link with 222mm Löfgren A. I think you not read it not even the link of OL protractor I posted.

@dover : "

Overhang for Baerwald A is 17.3mm "

 

I’m not wrong because I only gave neonknigth different alignment choices for his tonearm.

Who is way wrong with the numbers is not only you but OL too because 222 + 17.53 is not 239 or 9.5". One of my options that I posted puts the best number nearer to that 239 with a difference of only 0.1mm instead 0.3mm.

Anyway, numbers just do not coincide.
