Hi All,

Good day yesterday at our local large boot sale, got these items, one of which I am not sure of its exact purpose so any help would be great.

Pretty sure that the Ackworthie is a tapping accessory but have never seen the BOXFORD item before and have no idea of hat the MATRIX item was used for..

Cheers, Martin

Ackworthie is tapping head, Matrix is a bench inspection micrometer and Boxford looks like a bore sizing gauge.

`Hello Martin.

The Boxford item is a dial indicator as Clive says. It is for checking variations from a zero position ( In the centre of the dial ) such as centring in a lathe chuck, or on a rotary table.

Lucky you Martin, all I got was a small greenhouse (something I actually did want).

I did see a nice set of 3 M&W scrapers with tubular handles in a box but I've already got some. There was also a nice M&W small tap wrench which I would have had but the owner had stamped his (her?) initials in such a way as to distort the screw thread so that it couldn't be adjusted!

Martin (and BDH)

I'm envious. I don't know where you're located, but in my part of England (South Hampshire) the only stuff at local car boot sales seems to be clothes, old toys, DVDs/CDs, and household/garden junk. Never anything of use in the workshop.

Hello Martyn,

Where on earth is this car boot sale? It must be worth a trip to if there is such good stuff to be had.

The Matrix device is, as has been said a bench (inspection) type micrometer with a fiducial indicator on the left hand end of it. This ensures that the micrometer is always used consistently, that is to say it is not over over or under tightened onto the work being inspected.

John MC. is that the small dial with the discoloured cover?

Andrew Tinsley, You could try 15.9650° S, 5.7089° W wink, no guarantees of course......

Thanks folks for the info, the Boxford item seems very well made indeed and in great condition.

Regards, Martin

Mike, as it is quite a long swim I start the week before! The main problem is the swim back with all that metal so I have a very, very long snorkel...smiley

Seriously though we do work hard at getting all over to these car boots and find that the effort is rewarded.

We do think however that it is a fallacy that you have to be at these car boots at crack of dawn as often when we are leaving after a pretty bad look round we see someone just taking a box out of their vehicle and Bingo!, it turns out to be right up our street.

You get to be good at spotting the stalls that are never any good, lots of 'pink' usually means don't bother but you really can never tell.

Cheers, Martin

If the fiducial indicator and the micrometer itself are in good shape in a temp controlled 20 deg C room you can easily measure to +/-.0001" with the Matrix unit. The fiducial indicator part (big drum at left) is designed to accurately and repeatably control measuring pressure to achieve the higher accuracy than normal micrometers.

If bashed or left in the rain for months or years it may not be OK. If in good nick it is a valuable tool for close tol work.

Hi All,

Here are todays 2 car boot mystery item finds! The first is very strange and I have no idea what it is for, only 6 1/2" long overall, beautifully made from castings as shown:

smallman 1.jpg

smallman 2.jpg

smallman 3.jpg

smallman 4.jpg

smallman 5.jpg

Not sure if there is a square shaft part missing? The lever locks into position and closes the clamp section as it locks?

The second item is , I think, some sort of dividing head or indexing unit but no idea what for or from?

dividing 1.jpg

dividing 2.jpg

dividing 3.jpg

dividing 4.jpg

Should clean up OK by the looks of it. The really odd thing was that 1/2 an hour later at a different stall a clearance guy unloaded a really nice boxed MYFORD dividing head with plates just as I was walking by;

When asked how much he said "a tenner if I don't have to lift it back on the van"! Xmas is early!

Cheers, Martin

1. looks interesting [and, I guess, might be using forgings rather than castings]

2. could well be an equatorial telescope mount

3. crying 2

Hi Michael,

I thought forgings NOT castings just as I hit the "post" button, blush, castings would of course break easily.

Does the X Patent mark mean it is USA in origin? If so, probably quite old?

I had not thought of a telescope mount! Sounds about right, perhaps Neil will bne along with some input?

3 Love the emoji! Dividing head now gone!

Cheers, Martin
