Well, CDN Tire is having another sale on their digital calipers and on their micrometers.

The digital calipers are $14.99.

The micrometers are $13.99 for the 0 - 1" model, and $14.99 for the 1 - 2" model.

I already have the calipers, but I'd like to pick up a micrometer as well. I assume the 0 - 1" model would be the best for reloading, but I wonder if the 1 - 2" model would be useful too?:confused:

At those prices I am tempted to buy both, but I don't need any more tools that sit neglected in my toolbox.
 
micrometer would be serious overkill. what do you need to measure to 1/10 thou??? i've used them on engine internals, but that's about it. for everything else, a caliper is enough.
 
"...$13.99 for the 0 - 1"..." You get what you pay for when it comes to measuring tools. You know how to read a micrometer? However, a 0 to 1 will do for measuring bullets, few rifle case lengths though. Haven't found much use for a mike for reloading, myself.
"...tools that sit neglected..." Some times better to have it and not need it than need it and not have it.
 
I have the CT digital calipers and they work just fine. I've seen more expensive ones that look exactly the same but rebranded with someones company logo.
 
+1. Have the Mastercraft and it works.

Just be careful you are consistent in the way you measure, since you can get different readings if you use the point of the calipers Vs the inside of the "arm".
 
Once you get a decent dial you'll find the digital a hindrance. I have a couple of digitals but find myself going back to the Mitutoyo dial every time. For comparing measurements nothing beats the visual speed of a dial reading. Just my opinion which may or may not be worth $0.02.
 
if u seriously want to get into using a micrometer get a more expensive name brand like mitoyo starret and such they are pro used grear. i work in a machine shop and we will only use the more exemsive brands if u want a cheap but reliable model try kar or some mitoyo models. starretis the ultimate in accuracy. in the calipers the chepest yet most accurate would be dial or scale models u can get a good name brand pair like starret mitoyo for less then 150 dollors. thats my two cents worth hope it helps
 
Mikes and dial calipers...

I've had a 1" Starret mike for years and find that my dial caliper from Busy Bee just as accurate, to the 0.0005" while I also have an inexpensive digital caliper, it is a pain in the butt, as the battery seems to run down.

The dial caliper also works well for OV cartridge length and for roughly checking chamber head space.

IMHO, if $ is tight, get a dial caliper. (I also have a vernier caliper but the dial has spoiled me :redface:.)
 
i have one at home, the only differents i find between them and my starret's, or mitutoyo's (machinist by trade)are feel better and much smoother action and finish
 
I ended up buying the 0 - 1" model of micrometer.

Apparently, they are the best way to measure a bullet diameter.

It might come in handy if I do any gunsmithing, or any other metal-working.

I used to be a machine operator in a machine shop, so using one isn't difficult for me.
 
dial is great when you want to see changes in profile / smoothness / ramp rates, but for just checking overall length of a loaded cartridge or trying to figure out which bullet is which if a bunch fell on the floor, i'd think a cheap digi-caliper is adequate. i've used dial on an engine build (digital would have been hopeless & annoying).

i actually have all 4 types: digi-caliper, vernier caliper, micrometer, and dial "needle" (like a plunger, used to measure bumps or camshaft profiles)
 
0-1 mic is what you need to measure case head expansion to 0.0001.
It made a difference in the reload's I use when looking for a max load.
I worked at a place that make's part's for jet enjine's and just for ####-and-giggle's I bought a chinese 0-1 and 1-2 inch mike's and had them calibrated.
She had them for quite awhile but I eventually got them back WITH the aircraft certification sticker's on them! They passed!
What does that tell you about their quality?
And she did say she does fail the occasional Starret/Mitutoyo brand.

Where do you send them to for calibration and how much does it cost?:confused:

Also, how useful is a 1 - 2" micrometer?
 
Get the CT caliper and mic. For that price if they are junk just chuck them out. I find if you are doing just transfer measurements and it is only you as the user doing everything the cheap stuff will be fine.

When you get into tight tolerance and taking you own measurements to give to a machine shop, have something made and sent back to you and wanting it to fit get the good tools like Starrett or Mit.
 
They were set up and certified in house.
We made part's for Bombardier,Dehavland, the U.S. military,and a whole slew of other's.
Those chinese c clamp's surprised us all, especially some guy's who just spent 250-300 on an 8 inch solar digital digital vernier.
