In the spirit of Whitworth - What measuring tools do you use

[dromia]

OK so its Mitutoyo all the way then and Moore and Wright are off the menu?

Thank you for the clarity gentlemen.

Since you gentlemen know far more about these things than me I have parked my better judgement and ordered the following:

Mitutoyo 500-752-10 Caliper: http://www.lawson-his.co.uk/scripts/pro ... 20Calipers

Mitutoyo 293-344 DIGIMATIC Micrometers IP65 - 293344: http://www.lawson-his.co.uk/scripts/pro ... %20Digital

I am also toying with this as a possible acquisition. http://www.bowers.co.uk/products/show/3863

They should do you very well. Not sure about the internal though. The others I use quite often are a neck thickness gauge as I do a fair amount of neck turning and a bullet run-out gauge.

I assume the "Comes with FREE Glamorous Girls Calender" has nothing to do with the choice? :lol:

[dromia]

Actually I didn't go for that model because of the freebie, whenever I see give aways I get suspicious and avoid the product. :evil:

I have a good neck thichness gauge on my hardness tester.

Thought the bore measuring tool would be good for checking for muzzle wear which I do a lot of, just thought it might be a bit more informative than just dropping a calibre size bullet in, it would also give an indication of groove diameter.

The problem with using a calliper to measure bore wear is when the rifle has odd numbers of grooves unless it is a smooth bore, a better alternative is a set of pin gauges which are bars ground in increments, I assume you would be need from .200" to .500" which bridges two sets so it is worth looking around. Do not be put off by cheap sets as you have an incredibly accurate digital vernier coming with which to check them with.

M&W micrometres started losing out on the quality stakes to Mitutoyo nearly 25 years ago when the bean counters at the James Neil tool group told them they need to manafacture there pooducts more cheaply.
The first step making there frames a two piece affair, thats when i stopped buying M&W stuff and switched to Mitutoyo.

I am not sure I would buy the bore gauge I think there are better tools out there for gauging bores let me check on Monday when I can access my suppliers at work.

You can do the same with internal calipres and a micrometre if you have the right "feel"

Micrometer and caliper arrived today, seem like good pieces of kit. They both check out against my vernier micrometer and caliper which is reassuring.

The only thing is there is no on/off switch on them. :G

Have been thinking of getting a decent mic for measuring od's. Do you think it's worthwhile/necessary, e.g. for measuring neck od's versus using calipers ?.
