Warren, yes, I meant you. Should have been more specific. I'll have to go check out the linear arm thread. Limited time has prevented from trying to catch up with that lengthy thread after missing much.

You definitely have a robust arm frame.

Good idea on the fiberglass coating over the plinth.

Hi Brian,
Here are few pics of the build.

The bridge was designed so I could change rails to different style if needed. The uprights have blocks with brass inserts running on 8mm linear shaft and are individually height adjustable.

The rail support is held to the blocks with m4 bolts that have 60deg points that hold in brass Vees. This allows a small amount of forward aft movement to fine tune the rail for tangent and a pivot that can be locked tight to enable to rail to pivot for leveling.

The carriage wheels are 1 piece aluminium with 2mm carbide wedding rings as tyres. It now uses Vee pivots the axles are made from 1.5mm drills with a 0.1mm radius and the Vees are m3 cup head grub screws that have a 0.5mm radius. The Vee's were forged in the grub screw with another drill ground to the correct radius.

The carriage is a copy of the one Niffy made and is carbon fibre/balsa composite.

How does it sound OMG I have never heard vinyl sound so quiet, background noise (stylus in groove) is extremely low, and clicks and pops are almost a thing of the past. Not quite digital quiet but the closest I've heard.

I summed this up in a few words - Bass response, dynamics and eerily quiet.

Is it perfect - No I still have some distortion on inner groove with some female voices, I'm working on this.

That's massively impressive, pun intended. It makes me wish I was back to the Camelot days of my previous employer where we had a machine shop just for engineers to use for work-related or personal projects.

Any recommendations for a less expensive tone arm for my SP-10? I’ve got an old Grace 714 wooden arm on it from the 80s!

Grab it while you can—they had full stock a month ago—the 10" is the best bang for buck I have found—fit and finish is top notch—I am comparing it to my SME IV. (Not sure if you are US or not—these guys are based in Canada—poke around and you will find their Canada site for intl shipping.) Jelco is out of business this year. It's too bad. In fact i have half a mind to pick up a 12" before the prices get nuts.

Iíve gone for the old Audio Technica AT1503 mk.2 and mk.3. They can be found very cheap and sound incredible. Better than a Jelco SA750L or the SMEís Iíve owned.

Don't forget that the cartridge used will have great influence on arm choice...most low mass arms are totally unsuitable with low compliance cartridges - and visa versa!

You either choose can arm and then a cartridge to match, or choose the cartridge first and then the arm.
