Tri planar and shelter 901 and Verdier

Tenmus,
Assuming the jig is accurately made and used you are right, the spindle-to-pivot dimension will be set automatically. However, as Pcosta mentioned, I too have seen inaccurate jigs from TriPlanar. Mark the holes and check everything before you dril

As Pcosta mentioned and Dan_Ed surmised, the armboard on your PV pivots. Any slight inaccuracy from the jig can be made up here.

Dan_Ed,
Do NOT attempt to shorten/lengthen the arm by moving the arm tube in or out. You'll void your warranty and possibly do damage to the arm. The length of the arm is what it is.

Pcosta,
I agree the arm's effective length can easily be changed by adjusting the plate beneath the VTA tower, but doing that will also void the warranty. I inquired of Tri Mai on exactly that point and that was his response.

HI everybody

Thank you for your answers.

Doug
Now it' s clear for me , I 'll check the position before drilling...

I receive the tonearm at the end of this week , I'll certainly give you some news at this moment .

Many thanks again

Hi DougDeacon,

I was looking for a way to talk Tenmus out of moving the armwand, but your argument is right to the point.

Happy New Year all!

you can obtain very accurate rulers and protracters from your local drafting supply shop.
