Fidelity Research FR-54 Tonearm. ANTI-SKATE???


FR-54 Tonearm came on dual arm tt I bought. I moved it to the rear board, to use with Grado Mono ME+ cartridge, 1.5g tracking weight recommended.

All is well, but, I do not see any way to adjust the FR-54 amount of anti-skate.

One dangling weight, thru one groove in a wire, that's it. Bottom of weight has threaded hole. Presumably weight can be added, but, how lessened?

On scale, the weight is 2.5g. To a bimp on the bottom of the arm, just in front of the pivot. Does that mean it is transferring it's full weight, 2.5g of anti-skate?

I want cartridge to track at 1.5g, thus want 1.5g anti-skate.

I could grind the weight down to 1.5g I suppose.

Ideas?

Yes the skating force is due to friction between stylus and vinyl groove.It therefore stands to reason that the size of the contact patch afforded by different stylus shapes would affect friction and therefore affect the skating force and therefore affect the amount of anti-skate required.
yeah, the whole 'use my stereo cartride, listening, then good for mono' didn't prove correct, glad I figured it out.

gotta wonder why more turntables don't have different scales like that single Garrard did.

Glad I tried the grooveless smooth disc method, that is so easy.
