this was only a few posts up from you lol.
"Oh yeah...if you ever so slightly shave the hole under the screen of the upper chamber so that a 14mm M to a 18mm F jointed adapter slides in,..and then sleeve that 14mm joint w/ the silicone from the steel whip..you have a perfectly sealed glass on glass connection..you are then open to use ssv,,or lsv wands or any 18mm male glass wand.
Or use a 14m M to a 18mm M for other jointed applications."
Thanks for replying - I did see that post but did not understand what the poster meant by "shave the hole under the screen".
I want to try plugging a DBV whip into the upper chamber where the cooling coil fits. The opening appears to be about 14mm (a bit more than 1/2") so I'm thinking that a 9/16" vinyl or silicone whip might fit but was hoping to hear from someone who has tried it before I invest in tubing that will be useless if it's the wrong size.
Hope you like your Solo - that was my first vape but I didn't love it - had a bad experience with Arizer customer service and found a desktop (DBV) that met my needs better than a portable. Now I also have the Plenty but it's hard to pass around when I have guests (hence my desire to graft the DBV whip onto the Plenty).
