Just let me know here on x-ham your email address if you are OK. It's once sold on cost but never mind, now it's totally free and I keep strict privacy.
I'm terribly sorry not to reply to your request sooner. The tuck tutorial thing I made sometime ago was not published here but I specially made ready if you still want. But if you don't want to let me know your email address to receive this short video, just forget. I know some people have strict privacy and I am the same. And I don't want you either be disappointed to see the poor contents of my video un-professional instruction.
