yes u can, thats how i do it, so that the first nut down there block the second.
that way the whole thing doesnt move too much.
but for the mesh i wouldnt do it too large, its better when it has space at the hole so there is an airflow and its better for the capillarity of the mesh.
and the mesh, i think its useless to put it in the water when u burn it.
i never did that, and i dont really see any reason to do that. i remember people talking about doing that in the video tutorials, but then i came across another video where the guy said and prove it was useless.
but if u find it useful, why not; and again we dont have the same mesh and wire, so it might act different too.
one thing im wondering, do you guyz put the wire in a flame before doing your coil ?
i always do that so that but rapidly and succinctly, just make it turn red everywhere for like 1 second.
this will also help the wire to stick to the center post, well that way it wont move too much.
trials and errors, practice, the only way to get it right.
i dont always get my coil right either, and sometimes i have to do it twice.
but the way i do it, it takes me like 30 seconds now.
Hemps : i dont see why it wouldnt work with a genesis.
