A Copernican View of the Turntable System


Once again this site rejects my long posting so I need to post it via this link to my 'Systems' page

Thanks for that link Brad,
I saw it last week but could not remember where?
You're right......very fine machining work although I'd be hesitant about doing a platter? This requires dynamic balancing to very fine tolerances.... you don't want a heavy 'rocking' platter eccentrically loading the spindle and motor?!.....not to mention rocking the vinyl :-(
Yes Lew......some of the armpods are exotic indeed!
I suppose when they're attached to turntables that are priced in the mega-dollar region, the manufacturers can afford to splurge?
What we are looking for here......are alternatives to the 'expensive' armpod?
Are there any?
In_shore,
There were some previous discussions here regarding cantilevered pivoted armboards attached to the armpods as per Corby's excellent example illustrated some pages back.
To me, there are three obstacles to this in relation to this thread:-
1) It requires even more expert machining and metalworking skills which puts it beyond the average DIY audiophile here.
2) It makes it more expensive
3) A cantilevered swiveling and/or height-adjustable mounting board attached to the armpod, has many risks regarding stability, movement and rigidity.
The prime requisite in my thesis on the armpod is that of utter solidity and stability.

Strangely enough.....moving the heavy armpods on spikes is not that difficult.
Without the spikes however......the pods can 'glide' across the shelf with alarming alacrity. Co-efficient of friction of the two smooth surfaces must be low?
Dear Nandric,
I like your humour :-)
Unfortunately, sending one of my pods to Europe (including some specialised packing to protect the valuable object).....would cost heaps.....not to mention the Project Manager's time and effort to organise the building and sending of such a thing ;-)

But I might have something better for you?
Lying awake in bed last night......insomnia being a common symptom of painkilling tablets after surgery.....I had a Eureka moment like yours!
A method of producing heavy armpods for the cost of $20-$40?
And no machining skills required and the end result could be as beautiful as you could wish?
Is anyone interested?

Stay tuned and I will reveal my epiphany tomorrow ;-)

I was not aware of Corby's work, thank's for bringing this to my attention.
As nice as Corby's design looks and is I find it overly complicated for my requirements and perhaps as you mention plagued with stability problems.

My design is as simplistic as your pods are though mass is the only thing they share in common.
