Core Power Plays

The specs and strengths that make it shine.
Digital micrometers are preferred for ease of use.
I often find myself wishing they were digital, it would be super nice if I could go back and forth between mm and inches for the bearing fits.

Hidden Hero Hacks

Unexpected tricks and side‑door uses you’ll love.
Suggestions for sourcing micrometers include Craigslist and garage sales.
We need to replace it and I figured you guys might have some thoughts.
I've gotten my hands on several Mitutoyo, Starrett, and Browne and Sharpe mics for under $20.
Yep look on Craigslist or eBay for a used mitutoyo.
Small end of the adjustment wrench allows for disassembly of the ratchet sleeve.
What is the small end of the adjustment spanner wrench for on a Mitutoyo micrometer for?
lets you disassemble the ratchet sleeve iirc.
The adjustment wrench can be used for zeroing the micrometer.
Basically it allows you to zero the mic.
Restoration of antique micrometer stand
I've restored all the the mics in this stand (plus many, many more).
Very cool piece. Love the design and it looks gorgeous with that cheap paint gone and new wood.
Interest in micrometer repair techniques for Mitutoyo
Does anyone have any information regarding micrometer repair that can be done in house?
It's not Mitutoyo specific but it might be helpful.
In other words the most basic of repairs... And even then the mic may not be accurate.

Buyer’s Cheat Sheet

What to check before you click ‘Add to Cart.’
Used micrometers can still be reliable if well-maintained.
With proper care and maintenance these tools can last multiple generations.
Suggestions for buying micrometers include checking pawn shops and estate sales.
Check pawn shops. I’ve found some very good deals in the past.
Pawn shops, not second hand stores but good old "bet on the wrong horse and love my knee caps" pawn shops.
Quality can vary significantly among different brands.
I like Shars tools for the price. I would put them in the same class as Fowler and SPI for quality.
Budget constraints mentioned for purchasing micrometers.
We'd like to spend ~$100 max.
Discussion of alternative brands like igaging, Accusize, and Asimeto.
I'm very happy with igaging
Accusize and Asimeto would serve you fine.
Craigslist can be a source for good deals on micrometers.
It’s a good deal but I’m mainly posting because of the Doall dovetail cutters which are just *beautiful*.
Mitutoyo micrometers are valued highly compared to other brands.
pretty good.
Prices for micrometers vary significantly.
Got these for $100. Hardly, if ever, used.
Mitutoyo micrometers are seen as a good investment despite higher price.
Is mitutoyo worth the price? I'm seeing other brands that are cheaper but have n9t heard of them before.
Comment about resale value and affordability.
Nice tools that would've been expensive but in general everyone who wants an analogue mic has one!
Mention of a similar set's market price.
I can this exact set in the same like new condition sold for 99CAD which is 75usd.
Suggestions for other top micrometer brands.
Starrett is super top notch too
So that leaves you with these choices..Starrett, Mitutoyo, Browne&Sharpe.
Discussion on the user's background and tool needs.
I would like suggestions my budget is 250$.
only get what your tool list specifies though!

Cautionary Callouts

Know the pitfalls before they catch you off guard.
Mitutoyo is recognized as an industry leader in micrometers.
Starrett and Mitutoyo are the industry leaders. Can't go wrong.
Mitutoyo is considered one of the top brands in micrometers.
Micrometer Brands Does the brand matter when it comes to micrometers, the particular type I'm talkin
Regular calibration checks are important regardless of brand.
If I buy cheap I make sure I keep a little set of gauge blocks and every day before I use those calipers or Mics I check them on the gauge blocks to see if they are still good.
To be fair this is good practice no matter the brand.
I’d say any micrometer is a good one as long as you keep it calibrated.
Checking calibration regularly is important for all micrometers.
Just make sure you check it at various points.
Dovetail cutters can be beautiful and valuable tools.
Great to have when you need it but most likely will not find a tremendous amount of use.
The spindle and thimble are held together by a taper and can require tapping to disassemble.
it might need a little tappy-tap-tap to break the taper lock.
Discussion on potential thread backlash adjustment.
Thread backlash adjustment? If you have to touch that one better buy a new mike already though.
