VTA and HTA overhang

Theo, The Herbies Way Exellent II Mat is what I think Tom is referring to. I have one and have used it on a LP12. They are fairly light and work well on the Linn. They do make them in many different heights.

On my current TT I prefer a harder mat though.

I view perfect alignment if the stylus touches the inscribed arc at any point on the Mint protractor

Sarcher30, the mat I'm referring to is not the "Way Excellent" mat; it's the "Donut" mat found at the bottom of the Herbie's Turntable Mat web page. It's basically the elastomer wafer of the "Way Excellent" mat without the silicone foam base. The "Donut" is not intended to absorb vibrations so it's sonically inert for the most part. That's why I found it to be a good method to adjust for LP thickness and SRA on the Gyro SE.

Theo, I'm not familiar with the Linn 12 platter so cannot say if it will work the same as for the Gyro SE. But I will add that I also use a "Donut" on a Music Hall mmf-7 turntable, which has an acrylic platter, and the results are similar. The main difference is that I use a Way Excellent mat on the mmf-7 and it compresses slightly so I use the 0.81mm "Donut" to account for the compression.

Regards,
Tom

The only way the offset would not move when adjusting VTA up or down is if the tonearm post was curved.

The Eminent Technology ET 2 tonearm has a curved post for this exact reason. The part is called the arc block or VTA block. The arc block is stationary and the bearing housing rides the arc of the arc block as VTA is adjusted to keep overhang dead on.

Sarcher30, I didn't mean to imply that you took a position, that you really didn't. I should have addressed my last comment to "anyone who". Sorry.
As far as the various alignments, you still have them mixed up. Baerwald goes for even error at beginning, middle and end. Loefgren B has least total error. Maybe description on VE is confusing, but nevertheless.
