I can see I'm going to have to be the one to go out and get the silicone tape!
I can see wrapping a straw in it, cutting a hole in the top and making a little "drop-in" liquid reservoir!
I bought a 1" wide X 12' long by 0.020" thick roll of something called "Silicone Rescue Tape" at local Pilot truck stop this morning. Had to sell a pickup load of scrap aluminum to afford it. A box of 5 ncig cartridges and the roll of tape cost me $32.00.
This particular stuff only adheres to itself and is not easy at all to work with. I have made two '801' style cartridge fillers.
One by wrapping a straw end , applying a flat top and allowing the silicone to adhere and form a cap to the straw. Cut the X in this one.
Second one by cutting a broad cross, folding the arms down the side of the straw and wrapping a narrow band of silicone around that. Allowing to bond and form a loose cap with a slot in it.
Had a little flooding with the slot, none with the X. Haven't vaped either one dry yet. Keeping my fingers crossed. If it works I have enough tape to last for my great grandson.
Update:
Well, so much for constant feed from this type cartridge mod on 801 style. It does work great as a home made dobbit though.
Update2:
Until the top piece came off in the dark and drowned my atomizer and pillow.
Back to the stingy but trusty straw and fishtank foam plug.
