Thanks! I'll get a chance to watch the episode when I get home tonight and see if there is anything I can cover. It looks from what I've read, they are still ignoring the effects of repeated hits over time.
I'm also still invited to the convention, so I'll be going and at least I'll get to meet them...probably get to play up the fact my timing sucks .
Also got a nice compliment today...a friend of mine has told me that on close examination, my patternwelding is better than several makers that she knows. Apparently while I haven't made that much, I've make sure to follow instructions well enough that the material turns out better.
Now I just need to make more and put the grinder to work !
