One turntable with two arms, or two turntables with one each - which would you prefer?

 

"With a suspended deck its really not possible to run two arms on it."

Actually it is.  Many of us run two arms on

our Michell Gyro and Orbe SE's...

"Very difficult to work with,"

I find Panzerholz very easy to work with.

Sharp tools and lower Rpms. It machines

very well. Its not hard to work with but it is

hard on bits and blades due to the resins

thus the need for lower rpm and less agressive

use of tools to prevent the resins from burning 

onto the blades or bits used.

"Panzerholz is not stable -it can warp"

In all the years I have known of B25 Panzerholz ply ,

I have never seen anything even remotely to suggest

it is unstable or will warp. 25 mm and up in my experience is VERY stable to the point of being used

structuraly in many building applications . I have used

pieces removed from the base of massive machinery shipped in the late 70’s that were stored in the factory basement left leaning against a cold damp concrete floor in winter and hot humid in summer for almost 4 decades with zero warps or instability.

The layers of BEECH [its not birch] are layered between with the resins. The vacuum and compression leaves the Beech impermiated with the resins throughout. I simply cannot see any scenario in the home or shop that could cause an inch or more thickness of what is essentionly more phenolic resin than wood now warp or not be stable. Loft condos use it for self supporting stair structures. As far as sealing it, my experience tells me the edges seal themsevles when the blade heats and seals as it cuts. You can literaly polish it to a shine exactly as you would the paint on a car with a polishing compound.

Im with pindac on this claim in my experience for certain. Too many critical items are being made from it whom would not do so without data and reason to hang their shingle on.

Beech B25 Panzerholz, are you talking about the same thing. As my experience mirrors Pindacs and I know of no one elses whos doesn’t...Just know what Ive seen and experienced and never seen proof to refute it...

Beech B25 Panzerholz, are you talking about the same thing

"Never used these words - have no idea what you are referring to."

You said Panzerholz and that you used it and it warped.

I assumed then you knew enough about this product that you would know it comes in either B15 or B25. Either 15 layers of Beech veneer per 25 mm thick or 25 layers per 25 mm thick.

I reiterated the word beech as even in this thread others claim its birch wood.

Sorry, I would assume anyone familiar with the product would know exactly what I was refering to...apologies

As far as the panzer armboard being inferior to the gunmetal on a specific table. I can see that preference. Very dead plinth the liveliness that the metal brings would be missed by some so balance is a key here. Its a valid point one must be wary of over deadening in this application where one surface meets another for preference. As far as being out less than half a mm. Its sheet goods not d4s finished stock. For armboards some surface milling like any othe material be it aluminum , brass, stainless, ebony etc. etc...that would be a basic step.

Non of those materials come without the same variations in raw standard plate or bar uniformity.

Panzerholz is not a "soft" material.

Beech is chosen not for being waterproof ,

but because it is one of the hardest woods

and with high rigidity. Whether or not panzerholz

is your preference to use through experience

or not is all fine but the lack of basic knowledge of

it from its ingrediants to why they are chosen seems to undermine the relevence of "opinions". Long wordy explanations of what is basicly constrained layering

wont change the way some hear and choose. The popularity of light weight Rega tables proves that.

I’m quite certain that a slab of panzerholz can dissipate

the energy of a turntables self noise and the music

playback in its environment . The foundation it sits

on is actually a seperate problem.

Solve that first , ....

Besides we're off track on the OPs 

original question...

One turntable with two arms, or two turntables with one each - which would you prefer?"

I said "original" question...thats it above.

Evolved or not the thread topic is multiple arms

or not for personal preference.

Now with the brilliant deduction that borinized

steel is harder than wood I suppose your back

on track...

@dover

Perhaps you should learn to read before your stupidity and keyboard cowardice rise to the surface..

Panzerholz is a very hard surface resistant to impact quite significantly. How it machines is another story. This is what I said about it as far as working with it. Ive been working with it since the late seventies. However I think your density it would appear is far denser....

I find Panzerholz very easy to work with.

Sharp tools and lower Rpms. It machines

very well. Its not hard to work with but it is

hard on bits and blades due to the resins
