This time it's a solid one piece ebony armboard for a Technics SL-1210 GR deck.
A Linn fitting for both a Supatrac Blackbird sideways unipivot (interesting new arm) and a Syrinx tonearm.
The benefits of ebony over other materials are well reported of course.

Progress on the big Tannoy GRF replica cabinets.
These are made of 24mm thick premium birch plywood.
The 21mm supply that I'd used previously for the sides and back has dried up completely..
These are extra heavy of course.
The customer came down with the drivers and Mainly Tannoy new crossovers (very nice).
Also a custom grille and plinth solution. More about those later.
The cabs will now be finished, plinthed, etc.

The Tannoy GRF style cabinets for the HPD 385 drivers, I made have been finished and collected.
The owner is very happy with them.
He requested a different plinth arrangement octagonal, a large spike in each corner (something he already had, and liked the look), showing infront of the plinth corners.
Instead of half or long grilles an American made round mesh grille that fits snugly on a pressed flange that I fitted onto the front of the drivers.
The usual Tannoy front foam rubbers after easily removed.
A thinner strip of foam rubber was applied between each surface and the 8 bolts hold it all together.
Here are some pics.

A nice project all in 24mm birch plywood. They were very solid and heavy!

I had a request to fit a Pioneer PL-71 tonearm to a Technics SK-1210 mk2.
This is something I had done myself many, many moons ago.
The customer read about it.
The arm was good fathers. The Pioneer deck sadly no longer around.
The Acos made PL-71 tonearm Requires a very low mounting point.
Twice as low as a standard Jelco!
No problem, I have very thick solid Ebony blocks.
Lots of dishing required.
Here is my PL-71 arm fitted to my test mule deck.
Off to Norway.

Another TW Acustic Armboard.
This time in solid African Blackwood.
Super dense and hard. Only topped by Lignum Vitae for that.
Drilled for a Grace arm fitting.
With a recess machined in underside to allow the arm securing nut to thread on a bit more than the standard TW Acustic metal arm plate allows
Bound for the USA.
