SO . . . . . .
Here's an option for anyone ordering/"getting-on-the-list"-ing a mod. The
510+ post (which is also the juice feed tunnel and the nutted connection for the beryllium copper (BeCu) leaf contact) will be available in
Stainless Steel (SS)
or Brass (Brass) . . . . . I'm fabricating these myself. The brass offers better conductivity, and is easier to machine. I treat it (after all machining is done) in a solution of 2pts Vinegar and 1pt Hydrogen Peroxide. This removes any trace of surface lead, and it's been pretty well established that this is an effective process and that lead doesn't "migrate" or "leach" through brass. Whatever lead is on the surface got there because of the machining process. The SS is more time consuming for me, and doesn't have particularly good conductivity. However, the SS is more durable, less susceptible to tarnish, and probably has plenty conductivity for the average vaper.
You (all) may choose, as your specifications are finalized. At this juncture, they will cost the same. In the future, at my whim, I may charge a few bucks more for SS. If you really don't care, please specify brass. If you really do care, I don't . . . .. BUT . . . . do share.
Also, to be known hereforth, by all concerned parties . . . .. The copper plate is harder to machine, easier to FUBAR, and a bit more costly to me. For this first batch, there is no difference in cost to you (y'all). In the future, I may charge a few dollars for "the copper option".
We'll see . .. . .
much love . . ..
tah-tah . . ..,
