I have far grander plans than this, but need to refine rusty workshop skills.
I made a bottom feedable 510 connector out of parts from ft

which was one of these
$1.17 510 to 510 Adapter for E-Cigarette at FastTech - Worldwide Free Shipping
with the pin removed, and in it's place I put a positive centre pin from these
$13.61 Cartomizers for Pyrex Glass DCT (10-Pack) 10-pack - 1.5 ± 0.2
that have a nice long post. The head on the pin was too thick, so I put it in a drill and wore it down with sand paper
For the honing skills version I'm using a reo bottle set up and vamo board, but plans are for an sx350 running a 26650 with bigger bottle
I'll share pics as i [slowly] go, waiting on parts ATM
