Crow,
I bought one of these years ago at a flea market in silicon valley.
The man had two, one with a tip, and the other without. Thinking the
tips would be an easy lathe project, I chose the one which kept more
money in my pocket...
And have regretted it ever since<G>
What size tip(s) would you recommend for "normal" through hole work?
Ballendo
P.S. Any tips gained through use you'd like to share? Do you use
yours for SMD work too?
