I haven't worked on a bottom fed version. Was kinda waiting for you to chime in for that. The center post is a brass screw with a flat head at the connector and threaded to a brass standoff that we make. It's #4-40, but there is more space if you bore out and rethread the nylon insulating tube. I have 5 Brushed units, but they need assembling. Satins were only supposed to be a limited run of 5 with 3 already gone.
But I see the interest and might have to rethink that. There will need to a surcharge for Satin I think. Satin is alot of work on us since the engraving and finish work has to be done on a completely finished tube so to speak. Its the only way to make the engraving "bright" against the satin background. So the slightest scratch or any rub marks from collets, chucks ruin the tube very easily. Very dicey to do them.
All 3 posts are brass with Stainless screws. We make the posts also.
