I did say in my first post that I have a vamo and a provari. Also a multimeter, though I had forgotten the name of it. I only have a couple of batteries that don't have an ohm meter, and they are not 501 threaded. I definitely plan on checking the ohms of everything and also learning how to check for hot spots before I try to use anything. I'm getting lots of (what feels like, to me) conflicting advice here, which i totally understand is the nature of this sort of thing. Everyone is offering valid opinions. But... I have to sort through it and decide where to start. E.g. Protank would be a good place to start, but then maybe it wouldn't because it's too small and difficult to keep the wires from crossing and shorting. Aga or rstt would be a good place to start, but then again maybe not because working with silica is easier than working with mesh because the mesh can be a conductor. Terminator is good, but no, because it's too small and you have to join two different types of wire. I love all the Greek built options, but, even if I can find them in stock, I worry about availability of replacement parts if something should break. I'm not upset with the advice, but frankly I simply can't find something that everyone will think is a perfect starting place for me.
I ordered the aga t+ and a couple of terminator tt atomizers, plus some different wires and mesh and silica wick. I understand the tt's are going to be difficult to work with, so I will probably start with the aga. I will also try to rebuild a protank head, although it's been mentioned that will be difficult as well. Maybe I will try to rebuild a vivi nova too. I don't like them, but it's worth a go.
I have very steady hands and a lot of patience. Hell, in my last job I used to have to dissect fruit fly maggot eyes (imaginal discs) under a dissecting scope. Those suckers are, like 200 microns across. Of course, imaginal discs don't short out and blow your battery, but I'm pretty good with tiny fiddly things. Lol. I'm also very concerned with safety but I do appreciate the warnings. I will definitely be watching YouTube vidoes many times with the pieces in front of me before I start attempting this. I sort of need to have something in my hands though, before I start thinking too much about it. I'm definitely a hands on learner.
Again, I do appreciate all the input and I've tried to keep it all in my head as I was choosing things. I'm sure I will be trying other things as I get my feet wet.
