Best protractor for aligning to cantilever

Dmgrant1- You are the man!!! or woman!!! or person!!! I have some of their LP fluid, but did not know that they did protractors.

Dmgrant1 - thanks for the info.

Dmgrant1 i also want to give you a big thank you. What a drag dealing with you know who.

If you're trying to sight down the centerline of an alignment grid, having two images makes it possible to get precisely lined up. The printed line and its reflection are either directly on top of each other or they're not. This degree of precision is impossible without dual images.

I spent some time with my TTB protractor today and I see what you mean. If the lines were thinner and they got rid of those concentric squares, I think it would be a better tool, though.

If using a universal protractor, absolute precision in pivot-to-spindle distance is unnecessary. That's the whole point of an aimable protractor and headshells with slots. Pivot-to-spindle is a hair off? No problem. The protractor will automatically produce a pivot-to-stylus dimension to compensate. If the stylus is square at both null points your triangle is correct, by definition.

ok...I get it. Finally. It only takes 6 or so times to sink in.

BTW, if you're using a Baerwald protractor with an OL arm, you may have better luck mounting the arm at ~220mm than the stock distance of 222.76. Regas weren't designed for Baerwald and some cartridges aren't long enough to reach the Baerwald null points with the arm mounted at the stock distance.

I know we've discussed this before, but I've never experienced this as an issue (Shelter 501 mk 11 and a Denon 103R).

If the lines were thinner and they got rid of those concentric squares, I think it would be a better tool, though.

Agreed! One line through the null point plus one on either side for squaring yourself up would be better.

I can't think of any use for all those squares. They confuse the eye with alot of unnecessary information. Maybe they're intended for aligning the cartridge body rather than the cantilever, but why do that?

The Rega/Baerwald incompatibility will only arise if a cartridge's stylus-to-mounting screws dimension is shorter than average. I had that with one cartridge (can't remember which). An inward nudge of the armboard fixed that.
