My 6" calipers don't get used much at work. The 12" sure does.
Is that a lathe carriage scale .
Where did you get it.
How long have you had it
Is it home made or a true lathe vernier scale
It looks to be a very good tool to add the the lathe
Brown Sharpe 36" vernier caliper.
Got her cheap on account of the surface rust.
Was very pleased that she had no pitting!
Cleaned up nice.
Is that bar round
Looks exactly like this only 36". This is not my pic...
Also, mine didn't come with the 2diamonds.
I was talking about that vernier scale early
On in this thread that is laying on that big saw cut
Log . It appears to be a round Vernier
Don't look anything like the one you just posted
Scwhite : the yard stick is 2/3 round, the measure head is round on the right side,
I got it from a guy that his machinist farther passed away and was selling stuff off about a year ago along with a lot of other machinist stuff.
Rustrp: I was referring to its quality not who made it, as there are no names on it, hence built rite.
Some day I'll find a use for it , I'm not seeing a way to mount it on the SB 10L yet.
Is the ends threaded
Okay, I saw built rite and thought you were referring to the tool company in Massachusetts. I can find a use for the precision rule if you run out of ideas.
1/4-20 end threads
I have a 24" vernier caliper, but for most OD measurements, a diameter tape (pi tape) is just about as accurate and a lot cheaper.
I have a 12" digital caliper I use about 1/month. Just picked up a 24" manual vernier caliper. I admit it - I'm a toolaholic.
No a tape is not ether
Try the Starrett Vervier calipers model 123z
Master bar .
They are extremely accurate.
All you need to do is learn how to use them
The feel is a little tricky but they are very very accurate. 50 vernier divisions on them .
For anything over 6 inches my Starret rules and square have sufficed, I have a 12 and 24 in chrome satin that fit the combination square.
So I needed some stuff from Shars so I threw a 24" caliper in my cart. Ironically on ebay shipping costs for the caliper are 17 bucks. My order from shars with the caliper was 15 bucks.
One of my friends, a toolmaker, claims he did an assembly over 24 feet using only an accurate tape measure and a jewelers loop, holding to .003 tolerance all along the way... I know he holds incredible accuracy on his machines, so it lends some credibility to his claim. It was cheap enough to get an accurate vernier that was 24" long.
It's my guess that .003" will come and go with the evening breeze.
My largest caliper reads to 60"
You win ez.
Big callipers,Big bragging rights, no need to measure.
