One wick I made up was giving me a particularly rough time on the DID. I pulled it out, burned the juice off it with a lighter letting the flame go out naturally. I then retorched it for a full 2 min's paying particular attention to the ends and portion that touches the wick hole. I let it cool off on its own. Did NOT requench it, did NOT pour juice on it and light it again. Wrapped a coil replaced in DID, juiced the coils, fire, repeated 2-3 times. The whole process took less than 5 min's and it's been rock solid for about a month. No f1's, f2's, I've tipped it over on the table multiple times...the process seems to have fixed the wick for good. Might be worth a try.
It is extremely important on the DID to have the coil run coming off the ground screw lie flat against the top surface until it gets to its first wind around the coil. Only then do you angle it upwards to complete the wraps. I.e., you want almost no coil in open air in this particular section. Similarly, decrease the distance from the last wind to the post as much as possible without anything touching the post.
I wind mine counter-clockwise with the wire coming off the outside of the negative screw, not the inside. Works great for me and is extremely stable. Hope some of this helps.
