Torch drawback; conclusion - at last

 John, sorry  mate, .....but for the first time in the many years
that I have been reading your posts, I have to disagree with you.
I do agree with you that acetylene is indeed lighter than air, I
,just don't quite agree with your  density comments. 

G’day; I wondered if I should take Umbrage with those comments of
Mr Fischbein, but my dealer could only offer Burnt Umbrage and I
don’t like the taste; it makes me browned off.

However; my own comment is, “Enough is sufficient”. “Enough” was
disclosed in my first posting on the subject. – Cheers for now, John
