1st and foremost to answer drews question. i actually still have friends FROM ATHOL,MASS who are natives and 3rd generation employess of l.s. starrett.


each and every mfg over the years has manufactured a "homeowner"/"contractor"/"professional" version of their tools. ANY TOOLS!


it doesnt matter what it is. why? to grab all aspects of the market if possible.


call the low end crap a "loss leader" if you will. and obviously made OFFSHORE.


now if i was in an aerospace CNC machine shop, it would be MANDATORY to have what that shop/company/corp WANTS! it doesnt matter if its japanese or american or german.

ITS WHAT THEY WANT CUZ THEY SIGN YER CHECK!

upon entering such facility even BEFORE YOU TOUCH A PART..................it(yer precision tools) would go to calibration for OBVIOUS REASONS!


now lets say you drop yer precision tool and the measurement is OFF!


and lets say you check 150 parts per yer shift. and the measurement is WRONG!


then lets say the part goes to a secondary process, and the next guy looks at blueprints and does his process to the part on his next shift.


see where i am going with this? the part could actually be machined multiple times WRONG because of that 1st measurement YOU MADE!

now do ya see the costs involved and the REWORK!


but hey SAMMY-G-G knew that because he owns that shop in the picture shown. OR DOES HE? appears sammy g-g's shop does VALVES! as thats the only part evident in picture. i dont see any curvic couplers, hot rotating turbine engine parts, combustors,nacelles, or anything associated with AEROSPACE and TIGHT TOLERANCES!

and he mentioned the BP factory across the street, well unless BP(british petroleum) has gotten into aerospace and i havent heard about it, than BP does underwater drilling for oil. oil flows thru those valves. and we made LOTS of valves at BAKER PUMPS in downtown L.A.. right down the tracks from the L.A. COUNTY JAIL! a lovely area by the way that i spent lots of time at machining stone age valves out of stainless. not mar m/not stellite/not inconel/not waspalloy/ hastelloy/etc etc aka aerospace alloys with high nickel content and extreme RH(rockwell hardness)

i doubt sammy g-g has ever used WHISKA material and machined iconel.


but to question sammy g-g's INFINITE WHIZ-DUMB and the difference btwn what goes up in the air or SPACE...........................heres a lilttle common sense for sammy g-g's BOSS after his more than BRILLIANT STATEMENT and QUESTIONING what i did for the vast majority of my life.


0.002mm=0.000078" OR 78 millionths


so YES starrett tools CAN MEASURE that dimension.

and believe it or NOT any all mfg's of precision tooling have CUSTOM TOOLING SHOPS. so ANYTHING CAN BE MEASURED PRECISELY!

i have no problem with japanese precision tools, i have some. but the vast majority of shops that stayed in biz during the aerospace crunch in 1997(when i split) were JUDGED on their parts performance/delivery/lack of rework and rejection #'s. and there was a hell of alot of machine hops that went belly up. here in phx garrett cut their local vendors DOWN from 219 vendors to like 17 approved vendors. thats a hell of alot of biz space CNC's and everything else involved that went POOF! why cuz they tried to cut corners. snap on or starrett. if yer using it everyday and yer AZZ is on the line, you dont have TIME for problems. and TIME IS ALL YA GOTS! TIME =MONEY!

so YES sammy G-G YOU TOO CAN MEASURE HIGHER TOLERANCES WITH MM graduated precison tooling.
