150mm (6 inch) Vernier Caliper - Moore and Wright 100 Series

This is really nice. I have an electronic caliper that reads to .001, but that one eats batteries, so I have to take the batteries out each and every time, which is incredibly annoying. Next, the electronic one loses zero all the time, which means I need to double check every measurement. So that's why I bought a manual vernier caliper in 2017.Ok, the specifics... This measure inside and outside and depth. A little over 6" travel. The thumb thing is NOT a wheel, but instead a knurled rest that makes it easier to slide the jaws. It works well. The tightness is just right, easy to use. The finish is brushed stainless. It's not polished, or made to be fancy looking, but it's functional.If you've never read a verier caliper, you might want to read about it before ordering. It direct measures in .025" or I think .1 mm increments, then you use the vernier for the .001" or .02 mm. So you have to do a little math in your head, or on paper, here. And you need good light to read this thing. If you need reading glasses and don't want to wear them, this isn't for you.Oh, and pretty sure this is made in the UK, which is kinda cool. They invented the Merlin engine over there, so they do know something about machine tools.With this made out of stainless steel, it's a safe bet that it'll outlast me by a wide margin. Don't think that will be true of my battery powered caliper.

There is nothing I disliked. I have had dial and digital calipers. These are priced right and as accurate as anything I have ever needed really. I did check these against a high dollar set of constants and they are spot on as far as I can see. My eye sight is doing me no favors but I am reading them easily enough with my reading glasses. No more batteries or movements or crystals to worry about. PERFECT! Far less worry about contaminants on the slides too.

As a supposed precision measuring tool sadly this item fails. As can be seen in my photo the lower rail increments do not align accurately when fully closed so that all measurements taken are 1 to 2 tenths of a millimeter out. For precision engineering and professional goldsmithing this is unhelpful.
