What size did you drill the holes in the posts? Any pics? this could be the fix for my biggest "dissatisfaction" for this
tank lol.
I'll try to get some pics when I have to rewick. I have numbered drill sets that are TIN coated (titanium nitride), but you really need something like carbine drills for drilling stainless steel, it's hard stuff, not like drill mild steel. But I went into it knowing I'd most likely ruin a few bits and may even screw up the fogger, it was a risk I'm glad I took because it's so much easier to coil now. First I took a machinist file, just a very small file and filed a flat on one side of each post to make it easier to start the drill, I tried to center punch the posts but it just curled the tip of my Snap-On punches. I starting with a drill bit the size I wanted the hole to be, about 1/16 but because the bit would flex it was hard to get started so I started with bit almost the same size of the posts. Once I had a divot/pocket started I went back to a couple smaller bits until they dulled and I broke one, ended up the final pass with the 1/16 size bit. I did this with a hand drill and the fogger base in a small vise with brass jaws and I chucked the bit as far back in the jaws as I could but that's not the way to grip a drill bit, you should never chuck on the flutes. But as I said, I went into knowing I'd ruin some bits, slow speed, stop frequently and a drop of cutting oil helped a lot. When I was done there were tiny burrs left in the threads of the posts, with dental picks I removed most of those then I slowly worked one of the screws back and forth very gently until I was able to screw them in far enough to bottom on wire.
The negative post with the delrin insulator was difficult because to don't have much of the round post to work with, I had to get the hole at the very bottom of the post where it meets the square shoulder, I almost screwed that up because I now only have about two turns of the screw before it's back out. I have seen those negative posts selling for $7 so I may end up having to get another if the screw ends up too loose over time from use, need to find which vendor I saw them on.
Unless your handy with tools and have an assortment I wouldn't recommend it, I took the risk and it came out "usable". It surely isn't the right way to do it and it's not pretty but I'm happy with the end results. It would be great if we could find a member who is a machinist that would do these for us, I'd gladly pay a reasonable price to have someone do the next one for me.
