I am very of much saddened to hear of our 2pipers health troubles.He is an awesome dude, much knowledge & common sense between those ears.
I have asked him several dumb questions over the years via PM...& only received great advice,given in the most friendly of ways
When I read one of his posts,an image of a silvery,well worn micrometer often comes to mind.
Get well; my friend, & come back when you are
Wishing good thought for you
cheers man
