It's disease, auctions and me...

Just to keep Eric happy I came home with these today, (amongst some lesser items) one Mercer and one Baty bore gauge, both .0001" resolution. Should come in useful when I eventually get down to some precession boring needs.



And these, one Starrett Micrometer 25-50mm and one Verdict dial Gauge, .0005"



I was hunting down some info on the bore gauges, partic how to calibrate and use them, no luck so far but I did find this which gave me a bit of a shock  as I only paid about a fiver each for the bore gauges :bugeye:

Just hope I'm worthy.... :bow:

Darren,

You have been ripped off.

You need to have the Mitutoyo ones, which are classed as about the best you can get.

Mine range from 3K+ squid, to 8K+squid per set when new (I have 3 sets), next time you are over, ask to have a look at them, just so you can drool a little. BTW they have never been used, just calibrated, and put into storage.

The problem with mine is that they only measure up to 7.5mm (largest one)

The chinese are now banging out copies of yours for about 35 squid, so yes you did get a bargain.

Cost - F.O.C.

Now to get back on track. You should be able to calibrate them with a micrometer.

Result!!! Nice finds Darren.. It's like one of those "Antiques roadshow" moments.

Where are these auctions you go to? Sounds like a fun day out!

Hi Darren

I'm going to have to come to one of those auctions one day,  I'll hire a big van for the occasion  :lol:

You set the bore gauges with a calibrated setting ring.

Is the merser clock gauge missing its stylus if so I've got some I can let you have.

Cheers

Stew

It's actually a farmers mart David, sheep and everything, but you never know what you might find there. Quite a few of my tools have come from farmers  :thumbup:

I have a Mitutoyo digital caliper, Paid quite a lot for it too. I must admit I don't find it any more accurate than the cheap £7.99 ones. It's still goes out just the same when you slide it back and forth.

The old ones are the best John, good old british  (some American too) engineering, ruled the world with it at one time..... :thumbup:
