l want to build a solid wood turntable

Sam here and yes the shungite would have to be modified however the sound could be different + magnets would be used to make the vinyl more electric.

You need to look at at the Miyajima  cartridges. They are forward thinkers using cactus needles, which are considered wood, as a material for the cantilever.

What are you thinking of using as a stylus material for your all wood turntable? Ironwood or a cactus needle?

One of Soundsmith's top cartridges also uses cactus needles for cantilever.

Sam here and if a cactus needle can be used as a stylus needle i can dam well use shungite for at least the tone arm + if i water log the african mahogany i'm making the platter out of by submerging the wood in distilled shungite water for 3 days the wood pore's will open up and be energized by the shungite water then dried out with a heat lamp and the wood will be dry and hard like a piece of 100 year old wood with great tone.

No! Wood see I'll shrink and expand.
