Not worried.
We're all a bit odd (even tha'?) and it is one of my pleasures to have things tickety-boo in my workshop: if the emery paper manufacturers have gone to the expense of making and marketing differing grades then I may as well store them ready for use in that order.
I knew these grades by heart when I worked with them in the early sixties.
The differences are not easy to feel or see.
I could easily spend time with the heater on and minus five degrees outside, noting the effects of various grades on a sheet of metal but I thought that someone here could advise me, which they have done.
After a long break I am back working on the clock and about to polish the centre arbor.
I am very out of date. What would you use to get a really high polish on a roughish turned silver steel 3/16" x 3" rod? Perhaps there are labour-saving modern diamond-using that I don't know about.
What variety of model engineering demands only half a sheet of emery paper or cloth in five years?
