Here's a couple of Rega 3 point Arm spacers 6mm and 9mm thick, made from solid ebony.

Replace the multi layered and hole one that Rega supply, also pictured.



Customer fitted and sent this report to me.

"Just a little note to say that I fitted the ebony base you made to my RB303 yesterday. Listened to it last night. The improvement is massive.

I was bracing myself a little because it's a big faff for me to change the shim, as my tone arm is hard-wired in and it’s very difficult to get to the soldered joints and re-solder.* So, I didn’t much want to have to remove it again if it didn’t work. I was also expecting it to be ’too much’.

Every Rega owner should have these things. The difference is so huge. Detail as never before. It's like adding a mega cartridge, phono stage or even a new TT!

I have a superb phono stage and use a 2M Black as a cart, which isn’t bad. But I’m getting a properly high end sound now. So much more detail and less stridency. No more etched highs.*

It’s given my home-made TT a new lease of life, and will keep me happy for a couple more years while I save for a Vertere MG1 or a TMS3!

I am hugely grateful to you.

Kind regards,

Richard"

Brass work.
4 equipment feet in turned brass with threaded fixing, washers and nuts.

Also large Vitavox S2 threaded compression driver to horn mounting adapters. First one hewn out and roughly turned from a massive 4.5" diameter chunk of brass bar!
More to follow.

Update

Equipment feet in brass now polished.

Both large brass Vitavox S2 compression driver adapter fitting rings faced off and circumferenced. Thread cutting and mounting holes and edge polish to do.

Slight change in requirements on the Vitavox S2 screw on adapters.
The customer's original idea of a walnut ring did not plan out, so 2 rings in brass were made that bolt to the adapters (now look much more like the usual screw on aluminium adapters - this allows for throat alignment and tightening of the bolts).
The brass rings are secured to the horns by 4 countersunk wood screws.
Fun turning project.

Making a few upgrades for this Sorane SA 1.2 tonearm.
The original armbase didn't allow the arm to go low enough - the armlift pot fouled on the base.
It was also too loose and shallow, so tightening the securing grub screw put it out of alignment.

I've made a close tolerance brass armbase. The arm pillar is now a nice smooth, close fit and much deeper.

The moon shaped cut out to allow the arm to go lower is now in the right place too.

I've also been busy whizzing up a solid ebony, Technics SL-1210 armboard for a Origin Conquer arm.

Off to West Yorkshire for this one.
