What is PTB MisterD?
Pyramid Tea Bags, from Lipton i believe! Vapers started using this a a replacement for cartridge filling.
Using it to insulate the mesh is a great idea if it'll withstand the high temperatures close to the resistance wire. It may also be usefull in isolating the ss mesh from the Iatty steel cone.
I think it's time to start fiddling with my Iatty.....
