Best protractor for aligning to cantilever

Nrenter, I think the Dennesen addresses the concerns in your Issue #2. It adjusts for the triangulation between the table spindle, the arm pivot point, and the overhang. It includes an indentation for the stylus tip which falls on the proper overhang arc. While not a mirrored finish (as stated earlier, both metal and plastic versions were produced) there is a reference line etched on the surface that passes through the stylus tip point. I find this line easy to use in aligning the cantilever for offset.

My recommendation for the Dennesen is based on it's accuracy and ease of use. I've owned and used multiple protractors, including the DB, and the Dennesen is the hands down winner for me.

Unfortunately I believe both Dennesen models have been out of production for some time, but may appear on the used market from time to time. A new device, the Frickert, appears to be very similar in design although I have no experience with it.

Just to point out one real downside the TTB does have, its printed lines are pretty coarse. I'm sure the same protractor with finer lines (aka, a Wally) would allow better accuracy.

It's thicker than an LP, though it's not quite 3mm. For best results you have to raise your arm up to achieve normal VTA. No problem on some arms. Major headache on others.

Hello, you can get a custom protractor made for your particular arm for $90.00 from mintlp.com in Hong Kong. Good customer service. Just give him the specs for your tonearm.

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.
