BaerWald vs VPI setup protractors


Which is more accurate? Recently I decided to check my setup on a Scout using both the VPI gauge and a Baerwald protractor. Using the Baerwald the overhang is dead on in both locations, using the VPI the stylus misses the mark forward by about half a millimeter. Can this small amount of variance have a sonic impact? Has anyone else found this differene and what was your solution?

The Conrad arc protractor does well without a mirror because of the thoughtful design of the grid layout. If one views the cantilever straight on (not quite from above, but as though one is looking down a barrel), it's quite obvious if it's off by even a small fraction of a degree. I encourage you to try it for yourself.

I would agree with you when it comes to most other protractors, where the grid lines are much too far from the cantilever, or they only include one reference line down the middle of the grid.

The problem with the Mint protractors and the like is that they don’t measure at the exact height of the playback surface. One might be able to experiment with mats and such to approximate a similar height, but it still won’t be as accurate as placing thin paper on an LP. As I mentioned in my first post, another problem with most tractors is spindle hole size. All the Dennison style tractors I’ve used have too much slop at the spindle hole to allow for reliable results.

@cleeds We agree: I know very little about the world. At least I know enough to not assume, and to be civil.

I have tried many alignment jigs but after long term listening always go back to the VPI.

IMO....YMMV.
I'm all for saving money.  As regards protractors, my ship has left the dock.  I already own and have paid for the UNItractor, the Feickert, an original all metal Dennesen (I keep it for its historical value), and a Turntable Basics (which I no longer use at all).  For those who have not already shot their wad, there is apparently a free program available on the internet wherein you can dial in the name of your tonearm and cartridge and then print out a free arc protractor template, provided your printer will make 1:1 copies.  Do a search on either VE or VA for the URL. Honestly, I do not feel that the mirror is so vital to the procedure, although the UNI is mirrored.  Certainly, not using a mirror does not make one ignorant or careless.  If your cantilever is out of line, you probably can compensate for the error by guesstimate.
