[tabarddn51]

Hi Guy's, Just spotted this while browsing eating my lunch. Never seen anything similar before, anyone have any ideas, seller is located in the States.

Crap. Utter crap.
(and you have rather "miraculous" ability to find "tonearms" that should be dumped IMMEDIATELLY. This is not your first amusement with a tonearm lacking any means of horizontal angle error correction.)

It appears to be a Lenco headshell with maccano arm wand and a crap bearing which is a dangling thread.
Interesting to see but keep walking

Reminds me of the phrase - "just because you can build something, it doesn’t mean you should".

Somewhat reminiscent of a Yamamura or 47Labs. Different, for sure.

Where do you see a thread?

Where do you see a thread?

An educated guess, the arm appears to be hanging guided from sideways movement by the cylinder. See the pin at the top this is where I imagine the thread is tied too.

Looks like someone was walking by a construction site and thought to themselves "I am gonna build a tonearm that looks just like that crane". It is eye catching though.

 

[cason]

I thought that guy was on AK several years ago when he was building that arm.

Effective mass of, oh, give or take 2.5 kilograms.

 

[Aerobat]

Looks like a turkey baster attached to a cheap erector set clone that was left out in the rain.

 

[Buck Rogers]

Wow, Really well built.

But if i have to explain everything wrong with this design we will be here all day!

Another instance of reinventing the wheel...

I prefer linear air bearing.

I prefer linear air bearing.

Is the screw in the upper-right corner used as the oil-damper?

 

[Buck Rogers]

Yes, It's hovering over the oil trough as you can see.

Oil viscosity, The size of the screw head and depth in the oil, change the damping characteristics.

Yes, We have tried dozens of different viscosity's and settled on 50 weight Mobil 1, Best sound... No Smell!

Every year when I change the fluid I listen for a few hours without oil and it reminds me about some of what I do not miss about pivoted arms.

The sound is "Overly lively" in other words artifacts appear as extra high frequencies that obscure fine details. The difference between with and without is what I would call, Massive!

Inner groove distortion, Skipping or miss-tracking on warps, poor tracking on some recordings, Poor high frequency performance...

All the problems I've not dealt with over the past 20 years since machining this tonearm.

And I've got one left to sell...



See it in operation...

I congratulate whoever took the time and effort to make it, but ...
