Today is the day to replace cam follower pin in the Ford 960. No Nuday tools so what is 0.395-0.397 on this tool? Also what is 0.448-0.450. Thanks. Kevin in Central AL

Not sure what you're looking for, but all I had to do is highlight your number and select google and it showed me the fraction, but it's not anything common. If you have a good set of drill bits you could use them for a hole gauge.
 
Local ,small town stores don't have a good selection of drill bits. Not even Home Depot. Was hoping to use some flat bar and grind it to size.
 
This is one very old METRIC Vernier. Metric on the bottom. The top scale is in inch, with 16 lines to the inch. You can buy a very cheap inch Vernier that may be easier and more accurate for you to use, than the one you have in the photo.
Or you could convert the English requirements to metric and then use the metric scale on the Vernier.
25.4 mm in an inch. 1 inch divided by 25.4 is .03937
 
You can easily make your gauges but buy a cheap digital caliper over the one you have. You will be luck to be within .050 with that mechanical one as it is not a good one. The lines are too wide and "fuzzy". Home Depot has them for $19.90. I bought one for my road box just a few weeks ago there.
 
twenty bucks will get you a digital readout from harbor freight, but you better hurry my catalog says "everything must go" lol. gobble
 
The settings must be critical if they are carrying out the measurement to 3 decimal places with only .002 tolerance.

I could make some gauges for you and mail them if there is time to wait.
 
You are getting into micrometer reading if you want to get that exact.
No way you are going to adjust a nut on a turnbuckle that precise.
So get it close and let it ride.

50/128 is .390 and 51/128 is .398

57/128 is .445 and 58/128 is .453

Now all you need to know is how to read 128 of a inch on that scale.
If that is your question go buy a digital caliber or look up the video on you tube.
It gets more complicated than I would like to get into here.
 
You cannot make those precise measurements on the tool you are showing. It's just not THAT accurate.

If everything must go, then why do they keep restocking the shelves?

I always enjoy browsing around at Harbor Freight especially when they have the tent sales in the parking lot.

Even this chart does not break it down into .002 increments, but it will give you an idea
 
If you know how to read a vernier caliper correctly, it can be read down to .001". I've got a Machinist's and Millwright Handbook that may tell me. If so, I'll post it. I've still got a rotary dial caliper I bought 30 years ago snd my co-workers can't read that! Dumb-a..es!
