Anyone try the replica B-60 Fidelity Research VTA?

My sammle moved not only up an down but also sidewards.
The reason as far as I can judge is the pin on the screw
which connect the inner and the outer collar. The inner collar
slides along this pin up and down but if there is
any play between this pin and the notch of the inner collar
the tonearm will move also sidewards. This means that the
'replica' is not as 'exact' as claimed by the producer.
I assume that this screw is better made by the orginal B-60 .

I'll get the original Ikeda base in January, hopefully. 
So I can check then.

I figured it out. If you don’t have the set screws that pinch the tonearm stalk all the way in the adjuster stops. Thought I had them in far enough but didn’t. The first thing I noticed with this part is WHY would you put the set screws in a location where they can hit the adjuster? Also, it’s tight getting a wrench in there and depending on the positioning your set screws they can be covered up which means you have to lower the adjuster to even be able to remove your arm. Oddly, if you look at various pictures of the Ikeda online the set screws don’t seem to always be in the exact same location.

If you follow the instructions and do them up properly they dont hit the adjuster.

That’s to accommodate a large variation between turntables in the height of the platter surface relative to the armboard.

You want to set the postion of the pillar shaft such that the arm is parallel to the record when the VTA adjustment is dead centre with the cartridge mounted - this gives you the maximum VTA +- adjustment.

The original FR screws have an plastic piece on their ''nose'' to prefent damage on the aluminum skale or steel parts. 
Here's a good tip -
In my experience as a high end dealer most folk do up grub screws too tight and damage the surface of the pillar. This means small adjustments can be difficult because the grub screw will find the dent.

If your grub screws dont have the plastic tip, go to your gun cabinet and get some buckshot. Pop a lead pellet in the hole before you put the grub screw in. This means the grub screw pushes the lead pellet against the shaft and prevents gauging the pillar due to the soft lead buffer.

@dover how could they not hit the adjuster? The set screw holes are fixed in one spot and the “arm” that the adjuster knob is on is fixed in one spot.
