He, he, he..I lied.
I will posting an Instructable for the Caldera-Trodes.
Better display of the information and all.
The basic steps:
1. Layout the shape for the cone on copper.  ConeCad gives radius and span data.
2. Cut out the ends of the strip, and the outside edge.  Only rough out the inside edge.
3. Use a file to get the ends exactly right.  The outside edge should be pretty close to the line.  The ends and outside edge define the geometry of the shroud.  Make it right here, or do trimming elsewhere.
4. Needle-nose pliers, crimp the strip at regular intervals to form a cone.  Wide end of pliers at wide end of strip.
5. Solder the seam.  Carefully bring top and bottom end of the cone to round.  A good fit prior to soldering is a must.
6. Slice off the raggedy end of the cone at the right height.  Make the top and bottom 'circles' true.
7. Tin the edge of the 1/4 teaspoon measure.  Some stainless doesn't like tin/lead solder, so use lead free.  Not for ROHS reasons, just compatibility.
8. Solder the cone onto the PCB, alined with pass-through.  Use very little solder!  Too much solder or too long heating warps PCB.
9. Solder on spoon.  Two or three tacks, then flow them together.  Take care not to unsolder seam on shroud.
10. Drill itty-bitty [1/16"] hole through the copper, near the spoon end.  Vent and clean-out hole.
11. Do the same on the other side of the PCB.
I will post a link pretty soon.
