Feickert Protractor - anyone use one?

Agreed with stiltskin. I have a feickert protractor. The line and dots is so much thicker than mintlp protractor. That itself clearly indicates the accuracy of mintlp compare to feickert. Anybody want to buy feickert which I uses 1-2x pls email me

More agreement with Stiltskin.

Even if the lines on the Feickert were as fine as those on the Mint, which they're not, it would still suffer from the fatal flaw of not being built on a mirror.

Without the parallax effect afforded by a mirror, it's impossible to by sure you're sighting precisely down the line you're trying to align the cantilever to. Unless you've used a mirrored protractor you've no idea how easy it is to be off by several degrees - which defeats the whole purpose.

I humbly disagree with Stiltskin and Doug.
Alignment is only one of the functions possible with the Feickert. For me the greatest benefit is setting the spindle to tonearm distance accurately which allows the absolute effective tonearm length and overhang as specified by the tonearm designer.
Only those with adjustable (swinging) armboards (as on the Ravens), will appreciate this function but with the Feickert it is possible to get these accurate to 0.2mm.
I have the DaVinci 12"Ref Grandezza tonearm which comes with the Feickert complete with the set-up platter with one side dedicated to the DaVinci and the other side applicable to all arms.
I also have the Continuum Copperhead tonearm which comes complete with a dedicated Wally Tractor.
When I set up the Copperhead using the Feickert, I obtain 99% accuracy when I then test it against the Wally Tractor.
However when I try to set it solely using the Wally, I can achieve little better than 90%?

Halcro, sorry I don't quite understand your last paragraph, are you talking about measured pivot to spindle accuracy?
An arc protractor such as your Wally that inscribes a specific arc your cartridge stylus follows and if set up is done correct you will know the stylus is where it should be.
The proof is heard in the play back.

I didn't get this with Grahams ingenious set up jigs for the Phantom, nor did I get this with the Feikert.

Sorry Stiltskin if I was unclear.
If I try to set up the Copperhead by adjusting the cartridge to follow the arc of the WallyTractor which (correct me if I'm wrong) has the same mirrored base and inscribed arcs as the Mint, I can't seem to achieve a perfect match without taking hours and hours.
However if I adjust the Copperhead using the Feickert and THEN run it over the WallyTractor arc, Le Voila!!!

And yes you are right......the proof is definitely heard in the playback.
