Howdy Folks,
I too really like the mesh output when it works. Hard to obtain that fine line with it and it's really fiddly to get it right. I put one together this morning which turned out quite well. Make sure the mesh is spun pretty tightly into a tube or you will have a hard time spacing it between the posts. I found that after annealing it 5-6 times, and then burning it soaked in e-liquid 2-3 times works well, but I also wrap it in tissue before wrapping the coil. When you fire up the coil the tissue will burn and create an even better insulation. I also put some juice soaked tissue on the tube ends and fire it up with a torch. I have seen a lot fewer issues with errors on the PV.
I've actually gone back to the silica wick method for quick changes and taste testing as you can flush it and burn it dry better. I found that I was getting coil shorts with mesh after flushing with water. The insulation must have a tendency to wash away after a bit of use. A loose 4/5 Kanthal 32 wrap around two strands of the silica gives me almost an exact 2.0 ohms every time. The silica must slide around in the coil easily and then fluff the exposed ends before stuffing into the reservoir. The e-liquid will cause the silica in the coil to expand nicely.
Also, I found that removing the plastic insulator tubes from the pos and neg posts (they can be trimmed down a bit too) will help to avoid burning the plastic and allow more room to move the coil assemblies around if needed. Just take care when messing with them as the posts are only a press fit.
