If the factory recommended P2S for your tonearm is 258mm, and if you are reading 261mm with the Feickert, then you probably should investigate whether you can loosen the joint between the vertical shaft at the pivot point and the arm board, in order to move the pivot so as to comply with the recommended P2S. This ideally would be done BEFORE proceeding with any additional steps. Check the underside of your arm board. You should see a large nut or some other fastener that holds the tonearm in position in the horizontal plane and that would allow some movement of the tonearm pivot, if you loosen it a bit. Without correcting the P2S, you may have some difficulty achieving Steps 2 and 3. (Or you may not; there is usually some margin for error.)
Question about how to use Feickert Protractor
Greetings from Oregon,
I'd been following the discussion about the Feickert Protractor and finally decided to order one. I'd been using the GeoDisc for setup, and I wanted something a little more precise. I have been working with the protractor this evening, and the directions on the second step are not entirely clear. The first step is easy enough - set up the protractor with the gauge pin over the pivot point (easy to find on a unipivot) and adjust the cartridge to the bulls eye in the geometry you want (I'm using Baerwald). Moving to step two things become unclear
My first question:
Step 2 says "..we don't need to aim over the pivot point anymore. Please rotate the Protractor so that the stylus tip touches the cross hairs at step 2." The picture shows the stylus sitting right on the target. Correct me if I'm wrong, but that's not physically possible. The cross hairs at step 2 are a fixed distance away from the cross hairs at step 1. There's no way to rotate the protractor to make this happen. You have to move the tonearm over to step 2, right?
My second question:
Assuming that I'm moving the tonearm over to the lines for step 2 on the protractor, should the stylus fall right on the bullseye as it did at step 1? Mine doesn't, but I assume there's nothing I can do about it without having the whole tonearm assembly remounted. It's a VPI Prime, which doesn't appear to have any adjustments for pivot-to-spindle distance.
I hope the questions make sense, as it's not easy to explain without having the protractor in front of you. Hopefully, someone with experience using the Fleickert can help.
Thanks for any advice!
Scott
