Hi,

Thanks Big Al; its a case of you get what you pay for when it comes to wanting accuracy; the digital calipers are brilliant for general use and a huge help for novices unable to read a micrometer which we take for granted.

Sheffield Moore & Wright instruments are top quality as reflected in their price; I have two brand new cased M&W micrometers kindly given to me recently by a close friend and it's a shame to get them dirty but I also have other M&W micrometers which I've owned for many years; for extra accuracy when I want a precision fit I used my Mitutoyo 0"-1" micrometer.

Good point Joe about being able to change the digital vernier reading by simply applying a bit more pressure; micrometers though generally have a ratchet on the end of the thimble eliminating this difference giving constant readings. Where even greater accuracy is required then even heat makes a difference to instruments? For the ultimate precision lapping is employed.

All good fun but for the guy in a home workshop practice overcomes a lot; the best kit in the world isn't much use in the hands of a complete novice?

My Clarke engineering lathe is a decent little performer since it's expensive upgrade but it can and does annoy me in use; everything is so limited in size and the worst thing of all is that the tail-stock is locked using a spanner; how quaint?

Good luck Rob with your lathe restoration; are you going to use Paragon machinery enamel to finish it with?

Kind regards, Col.
