You may wonder the difference between African Blackwood and Ebony. Both are hard and dense. African Blackwood is not quite as dark in natural state. It is denser and harder with a tighter / almost no grain its so dense. Due to this it machines and drills very well indeed.

I can't say what acoustic difference there is between them though, as I've never had the opportunity to listen to them back to back on identical equipment.

Here it is mounted (to ensure perfect fitting) on my scruffy test SL-1200 deck.

Here is a set of weights (heavier antiskate), lateral and custom mass counterweight for the mighty Fidelity Research FR64s tonearm.
Made in 303 grade stainless with semi polished finish to match the arm.

I used the same sized grub screw / hex key sizes as the originals use.

Also a couple of Tonearm mounts - one for the Thorens TD-124 deck in Ebony.

A bespoke tonearm pod for an Audio Technica 12" arm from an African Blackwood block that fits to the rear of the plinth.

Here are a couple of projects for Rexton

Armboard for SL-1210 with SME V fitting.

A counter weight in 303 Stainless steel specified for an SME 3012 tonearm. The original weight was too light for the intended cartridge / headshell and was nearly off the back of the arm stub. This baby will balance things nicely.

WOW! Cant wait to try these babies and you need to update your sig, that SPU is coming to Wakefield dude!

Nice one, Steve - fab work as usual! And congrats, Andy! :)

Trust me, you won't regret going for an ebony armboard. Prepare for some long nights ahead rediscovering your record collection, as it'll make your Techy sound more musically addictive than ever!! ;)

:lolsign: here's hoping so! I bought the custom counter weight as an extension to my own Denon 103 experiments and also research into Ortofon SPU's. :D

Here is a finished SME3012 extra heavy counterweight including drillings and grubscrew for slider bar for the fine balance weight.
