CALLING SPARKING CHIP

Andy


There is a splendid set of carpentry tools at the moment on Ebay. Just search for GTL tools and scroll down to the tool chest. I thought you may be interested and I could deliver it to your relatives address for collection.

    ... slide rules were invented by carpenter.


    How many of you use a Mear Calculator?




    According to Wikipedia, so it must be true, he was a sky pilot. Based upon Napier's work, but his bones were slightly different. Yes I have used a type of Mear calculator.


    (I once met a man by the name of Napier and asked whether he was connected with the engine manufacturer. He said no, but Napier as in bones.)


     




    I thought I recognised the name. I have the heating calculator, it is rather old now, like me,  so I have to do my calcs in feet, inches and BTUs. Not often I use it these days. When I did O and A levels they kept on changing the units so I used ft/lbs, MKS and then CGS with all the associated units such as poundals, ergs, and many more I have forgotten about so I am completely at home with feet, inches and BTUs
