NSFW Last Word repair

[GeneT45]

I bought one many years ago because they were talked up in one of the Machinist's Bedside Reader books. Fast forward a decade or so and I worked where we had a shop with some very talented toolmakers. In talking to one, he told me the very same thing @RaisedByWolves is saying. Haven't touched it since...

If you've already had pieces go flying then the battle is already lost- I'd just get another one. Life is too short

how did you clean it. I soak them in clean mineral spirits, then compressed air at like 10-15 lbs to blow the ms out. that usually unsticks them.
I have a super old one, where the dial does not move. I don't use it much. Only when I can't get my existing snugs to work for me. It's a last resort. My Mitutoyo test indicator or my bestest are my first choices.

Hi, I put the parts in my ultrasonic washer for about 30 minutes with soapy water, I think I should have just used mineral spirits or lacquer thinner.
I have a good indicator, just trying to repair this one

Starrett has recommended removing the screw plugs and using:

• Isopropyl Alcohol
• Non-Residue Electronics Spray Cleaner

For crusty micrometers they soak them in Marvel Mystery Oil for 1 — 2 weeks and they come apart reasonably easily. For a really nasty/rusty mic I got in a mixed lot of stuff they were OK with:

1. Surface Clean with (real) Mineral Spirits & Brush
2. Marvel Mystery Oil Soak
3. Disassemble Then Soak Rusty Parts in Evapo-Rust

(Actually, the Tech initially told my contact to use Gasoline or Lacolene, but in any case stay away from soap/detergent & water as it will leave a residue)

RBW is correct... they are basically disposable...

I've owned probably 6 or 8 of them... I've never seen one that didn't stick.

I still have one... it is the most reliable of all the ones I've owned. That's not really saying a lot. I keep it mounted on a reloading press to accurately seat rifle bullets to a consistent depth. It works for that because I'm watching it move, then return... if it sticks, I know it immediately.

I'd toss a broken one long before I attempt a repair.

My vote is Inerapid. I have 4 of them the newest one is 30 years old. My first one finally failed lest year. That would be 43 years worth of use. Work ones are sent out every year for calibration. Never needed a repair. Tips yes.

I do have a few last words for home use. I always double check to make sure they don’t stick when using. Just a light touch. Easy to service as stated above.


Cutting oil is my blood.

Hi, thank you for your help with this, when I get a replacement screw I will try this.
do you know what the thread of the pivot screw is?
