Steamer, I'm just guessing but there's been a few complaints about that problem.
The Ni200 I have is tempered. I pulsed it tomake sure there were no hot spots, so there went the temper. The twisted held enough strength to get a reasonable wick in after pulsing it. That's 28 gauge Ni I have on hand by the way. The only thing I use it for is that old, but very reliable, DNA40 low tank I kludged together.
You know I also have some of that Ni200 Clapton Bill turned me on to, I got that just for the Merlin's but only used it a couple times, I can send you some of that as well. Man, my head is really up my .... today, sorry... I've been having a real rough time with the spine the last week and a half, hitting the pain meds and heating pad at max. The doc to sent me a short term dose of steroids to help get me past this hump, only 2nd day in on the steroids so hopefully a few more days and I'll be back to "normal for me
