Wanted: Mpingo spacer for Denon 103

[walpurgis]

high heat resistance
high resistance to chemical agents and solvents
high anti adhesiveness
high dielectric properties
low friction coefficient
non-toxicity.

PTFE is generally considered a thermoplastic polymer; at 327°C it maintains a very high viscosity, thus requiring particular transformation techniques for manufacturing of finished and semi-finished goods.

PTFE can be used at any temperature from -200°C to +260°C peter

Erm. We're talkng about use as a spacer in a headshell here. No extreme conditions involved (I hope).

Thanks for offering.

Don't think I've got Delrin knocking about, but I have PTFE, a bit of nylon in various forms, acrylic plastic, carbon fibre tubing and sheet, epoxy sheet and tubing, various hardwoods and many metals. Must get around to using it all up really!

Peter, I have a carbon fibre spacer you are welcome to have.

Nice one Jerry...

I've got sheets of Styrene, it's not hi tech, but a nice soft plastic made for modeling. And I've got it in a dozen thicknesses, as thin as .010", and as thick as .080". Real inexpensive. I've made a shim to raise the tone arm mount out of it, so easy to work with.

Thanks everyone for the replies, especially Jerry
I think I'm sorted now.

I am reading this with interest as I need to make a spacer for my cartridge (Ortofon AS212 tonearm that is too close to the lifting arm) and would benefit from perhaps 3mm additional depth.

I am on the verge of ordering a sheet of paxolin but wondered if anyone had experimented with balsa wood ?
Only asking as I have various sheets/sizes and was thinking of mocking a spacer up as a test to see if 3mm was about right or whether less/more thickness would be better. Suppose I could always give it a listen.

Anyone tried it ?

As I recently posted on another thread, I once heard a loudspeaker with a cabinet made of balsa wood. It sounded amazingly natural and remains (in my memory) one of the best speakers I have heard.
Maybe it would be as good as a cartridge spacer?
Certainly worth a try!
