Hi Chas,
sorry for the delay in my reply, but yesterday appeared to be Zombie day. I had a severe case of an alcohol free hangover, I can only put it down to too little sleep, I was in a dozy state the whole day. I was also afraid I'd post a whole lot of rubbish, or something stupid. Nett result was I hit the sack early and slept for over 12 hours.
I'd like to take up your kind offer, that is if it's no skin of your nose.
But I must point out that it
might not be returned till near the end of the year.
Looking at the construction of your tool reminds me of 'mater artium necessitas', necessity is the mother of invention. I've come up with some things in my life, but this is definitely one that would never have entered my mind.
Cheers.
Karl.
