This protractor is designed to provide an easier safer more accurate method to set your Shure V15 Type III cartridge.

Unlike current protractor design this protractor does not depend on one's eyesight to make adjustments and unlike current designs this protractor safely protects the stylus during adjustment.

Current protractors depend on aligning the phono cartridge to a printed grid pattern with the stylus placed on the grid. Alignment is subject to discrepancy when the shape of a cartridge body does not conform to the printed grid pattern and errors with unreliable line sight alignment. Also the stylus is unprotected from damage.

Current protractor designs were created when stylus shapes were much simpler and inaccurate alignment more tolerable. Newer stylus shapes require very accurate alignment to work at their full potential.

This protractor eliminates inaccurate line of sight errors and protects the stylus from damage.

How to Use

The cartridge is loosely mounted onto the tonearm without the stylus and the cartridge placed into the protractor. Adjust the cartridge at tonearm so that one of the spindle holes of the protractor can be placed over the turntable spindle. If needed, adjust cartridge so the other protractor spindle hole fits over the turntable spindle. Adjustment is complete when the cartridge requires no adjustment to fit both spindle holes over the spindle.

My main objective with these protractors is to improve sound quality. All of the protractors worked very well on my turntables. They have never sound better.

Important Notes

This protractor is only for the phono cartridge listed above.

This protractor is 3D printed using PLA plastic filament.

FITMENT: The GRIMM’s protractor will work with most all pivoting arm turntables. The protractor positions the stylus tangent to the record grooves at the two calculated Baerwald null points regardless of arm length. The Grimm's protractor will only work with the cartridge it is designed to fit.   FEEDBACK: Simply Brilliant !! I have installed and aligned cartridges since the late 60's - probably a couple or three thousand. Own a half dozen alignment tools/protractors (maybe a few more than that?). Bought the AT VM-95 and Shure V-15 type gauges -this is not only fast and accurate -but because you can simply hold the cart body into the fixture with your thumb it has no tendency to twist in the headshell as you tighten the mounting bolts.
Excellent product. I aligned my cartridge with a protractor and it always seemed off. This gauge eliminates any guesswork. Very precise. System sounds better as a result. Great value, pro packaging, fast shipping, better than described.   Great tool for adjusting a turntable, shipped very fast and secured, seller is an asset to ebay. A++++

This seller is very customer friendly I asked many questions and he always respond and answered all my questions I highly recommend using him fast shipping nice protector

These custom cartridge alignment protractors are simple and easy to use and much faster than traditional protractors.

This tool will be a great help in setting up these Hana cartridges. It is difficult using line of "sight" for setup using many protractors on the market. Thank you!!!!
