Re: Is Teflon is bad for silver?

Yep, I have the teflon milled, drilled and tapped as just have .750" holes in the .25" aluminum back panel for RCAs to pop out of so the teflon has to be dead on the money so we run it on a CNC machine....They charge pretty well for that, but that was for three units...

How dead is dead-on? 0.005" is standard with premiums charged for tighter tolerances. 0.005" is about the thickness of a piece of 24 lb. printer paper. You need tighter than 0.005"?

Why don't you just give the machinist some ABS and have them make you a couple of templates, get a router table, a drill press and some taps and do it yourself? You could crank 'em out all day for a fraction of the cost.

Send me a dimensional drawing and I'll make you up some maple ones to try when I get some time. The maple's from 250+ year old old growth trees from the midwest forests and have been sitting at the bottom of the great lakes in an oxygen-free environment for a 100 years or so ("sinkers" that were lost during transportation by logging industry over the years). Pretty cool stuff.

You get murdered on tiny runs done right unfortunately...

Yup. It's all the set-up costs. They don't amortize out too well with small runs.

I thought about using the teflon slip washers, but wanted lower capacitance and this teflon trick works great, but is expensive to execute....

Yup. Though I think you could do it in-house for a lot less in the long run.

Oh, stole this from BEAR Labs BTW who had used it on an amplifier....Picture of the teflon and back panel in my gallery....

Thanks.
