Best protractor is no protractor. Get a parallel tracker.
Parallel tracking arms also require alignment. Azimuth, VTA/SRA, overhang.
More correctly, a parallel tracker has zero overhang. How can you ensure zero overhang when setting up a parallel tracker? On most of them, you need a gauge or protractor. |
I have a bunch of gauges, including the Denneson and CartAlign but my favorite is the original arm-specific Wallytractor, just like @wrm57. I do not think they are currently available. |
