Sunnyboy,
On my arm the difference in overhang between Baerwald and Lofgren is 0.5 mm.
I can, and do, see the difference between the two with overhang and alignment on my Feickert . I can also see this difference with the WallyTractor. Both are equal in the usefulness. Where the Feickert may have an advantage is in the ability to align any pivoted arm.
Just like any tool, it takes time and patience to gain a better understanding of it abilities. Both methods (Feickert, and Arc types) prove to work well for my use and both, when mastered, will provide exceptional results.
If you are up to it, you can try to spend some more time with the alignment tool. The first thing to check is overhang vs. the two alignment types (Baerwald and Lofgren)to make sure they are NOT the same. They should not be. The other thing to notice is that upon a quick look the alignment may appear similar but the cantilever will not be aligned at both points because it's not theoretically possible and in practice I've verified this as the Feickert has very good resolution to be able to align the cartridge to a fine degree. Again, as verified with the WallyTractor.
One thing you may want to try if you haven't is mark the pivot point on the RB1000 arm you reported in the thread above that you have. This point is very important to getting the alignment correct. This is important whether we provide the number to an arc protractor maker or if we use it in real-time to set overhang with the Feikert tool. It ends up being critical to the adjustment as well as assuring precise repeatability, IMO.
What all this really points to is the importance of getting to know and use the alignment tool of choice. The more you use it the better you become at maximising it's ability to accomplish the job. Both types of protractors require patience. The more patience we have the potential for better results become or reward.
Hang in there and I hope this helps,
Dre
