Wouid you be willing to share your prepping list with the group, for reference?
Sure...
5x Kayfun Lite Plus
5x King mod
5x Kayfun spare base
5x Kayfun spare chimney
5x Kayfun spare tank
10x Stainless drip tip
5x Brass drip tip
1 Liter 100mg nicotine
The only 'frivolous' purchase among these is the brass drip tips to match my Caravela clone.
The reason I chose the Kayfun is that I am a tootle puffer, and the Kayfun is an older and well-understood tank design.
This means that there is plenty of info and spare parts available.
Also, the Kayfuns have a plastic tank and an optional steel tank.
I normally prefer glass, but polycarbonate is much less likely to break, and I have the steel tanks for when I break all the plastic ones.
The spare bases and chimneys will allow me to make 'cartridges' - prebuilt coils that can be carried around as spares.
The King mod is an older design, and thus inexpensive. It is also very robust, having thick body tube wall thickness.
I'm getting the stainless steel ones, as brass and copper are too soft for a mod that may have to last several years.
I do like regulated mods, but they are an unknown quantity.
They may last for years, or they may fail in weeks.
One unlucky drop could kill a regulated mod.
Mechanical mods are less 'user friendly', but with care could last almost indefinitely.
The reason that I have bought several identical items is to allow the possibility of making one good item from two broken ones.
Unless all of my gear happens to fail in the same way, I'll be able to cannibalize parts to fix breakages.
I also have the option of using my metal lathe to make replacement parts, but that obviously doesn't apply to most people.
Using the lathe is a last resort really, because it's more difficult and time consuming than most people realize to make something like a mech mod on a manual lathe.
Although I could make a mech mod from scratch on my lathe, I'd MUCH rather spend $10 now on a spare mod than have to spend hours boring out tubes and single-pointing internal threads.
Sundries such as wire, o rings, PG, VG, food flavorings etc will still be available, so I'm concentrating on the other stuff for now.
I vape approximately 3.5ml of 12mg juice per day, but I intend to step down my nicotine over the next year or so, so I'm expecting my nicotine to last ten to twelve years.
