If you drilled it by holding it with your hand, I don't doubt you had problems. If you use a drill press, or even one of those drill-stand adapters for a hand drill & some cutting oil, drilling Titanium isn't that bad. I've done a bunch of Ti motorcycle and gun parts using just a cheapie drill stand. While it take a bit of time, its not any more difficult than drilling Stainless Steel....even with a cobalt bit. I've used both Ti & cobalt bits and both worked about the same as long as they are kept cool.
Titanium work-hardens with heat, so if you get it too hot, it makes it even more difficult to drill. The real trick is to use SLOW speed ,and plenty of cutting fluid - I use Kroil, but tap & die lube works fine also. The Cobra deck is pretty thick to boot, so you really need to take your time. Don't try to drill it in one continuous operation - back off once in a while to let things cool down, drill slowly so you don't get any galling, and use plenty of lubricant.
No biggie...at least you got it done, and it looks like i works fine. Nice job!
On wraps and heat up time for thicker wire, I look at amps. If I am not putting at least 3 amps through 28g, their is too much delay in getting the wire to temp.
