Latest tool buys

Adding to my vast collection of measuring tools. I picked up a few used specialty micrometers this month. $25.00 each..

Brown & Sharp #215 Disk Micrometer 0-1"




Lufkin #3611 Disk Micrometer 0-1"




Lufkin #1951 Blade Micrometer 0-1"




Blade micrometer is used to reach bottom of  a narrow grove.. Previous owner altered this mic by grounding the spindle to a smaller diameter, and relieving the frame above the anvil.. Still usable and accurate...


A disk micrometer is used to measure groove widths.

Wow I never knew Lufkin made precision instruments.

You bet they they did. The quality of Lufkin precision measuring tools was equal to Starrett during their entire run and did not drop off at any point. The price point OCG bought his disk mics at was exceptional. Disk mics can routinely be found on ebay but at higher prices since they are specialized in application.

Lufkin sold off their precision tool division to Pratt Whitney in the 1960's and they continued producing the Lufkin line with the only change being the Pratt Whitney name replacing the Lufkin name for a few discontinuing the entire line.

Today, well preserved examples of Pratt Whitney precision measuring tools like outside mics in original boxes show up on ebay at greatly inflated prices.I have no clue if people pay these stupid high prices for them or not. Three times I lucked out and bought Pratt Whitney outside mics in various sizes in like new condition in like new boxes for very cheap prices.

OCG made a very enviable purchase in my opinion at a great price point of high quality instruments that always feel like an old friend in the hand and usually buttery smooth and dead nuts accurate in use.

For certain Lufkin always makes top tier precision measuring instruments. Along with all USA made micrometers have that butter-smooth feel spindle. Some foreign brands like Mitutoyo and Flower fall into that category as well..

My first precision tool was a Lufkin 1" micrometer, that I purchased 65 years ago. It rests in my tool box drawer in the original box. Along with my father's lufkin 1" and Brown & Sharp 1" mics. A set of Mitutoyo 1", 2", 3" mics. And a Starrett 1/2" that I snagged over the years...




Set of Mitutoyo 0 to 6" and 6" to 12". All carbide tipped.



My set 0" to 6" Fowler carbide tip micrometers in a mahogany Starrett case no less... 




Then there's this Dasgua Digital 1" to 2" micrometer that a friend gave me when I was machining some parts form his 1910 Locomobile. Must have felt I couldn't hold the tolerance with one of mine...  Digital is fine, but I'm more comfortable using my old-school analog micrometers...
