Not sure what i have ..
« on: April 12, 2014, 05:01:27 PM »
Bought a couple of gauges, and some type of fixed micrometers ??

2 of the gauges are marked:  1 div. = 1/4 ounce.  Pressure gauge ?

The other showes  .001 - 1.000" and has a mounting tab on the back.
Fixed location dial indicator?

The little right angle things are from Mitutoyo , and look like micrometers.

Any ideas on  these ?

The logo is for Federal Guage, which used to be in my neck of the woods. (Now part of Mahr)

Weird scale size, dunno what it was for...
(They made guages for **everything**)

Nice tools!! Great 1" travel dial indicator, Others looks like something to measure spring tension/compression & travel...

The little right angles were something from a dedicated gauge. Some shop somewhere was machining a production run of parts....they made up a jig or fixture to nest the part in, then fabricated and positioned the micrometers to inspect a certain feature. Probably there was a "master" part that they used to zero the micrometer heads to.

The micrometer stops can also be useful as carriage stops on metal turning centre lathes (center for you folks in the USA) - they allow depth to be adjusted by 1/000 inch steps if required.

The tension/compression gauge I have no idea as to its use, but it could be used in clockmaking to measure torque on a gear wheel or mainspring...

The other dial gauges are also used in precision engineeering, e.g. to 'clock' a workpiece central when held in a 4 jaw independent chuck...
