Starrett 711 Last Word Indicator

QKS07Z90LAA1 

New Last Word indicators can be bought from any Starrett distributor and most catalogs carry them. There are numerous variations all having to do with the kinds of attachments that come with the indicators. The ABC part of the Starrett number alludes to these attachments. Darn if we can figure it out but a careful study of their catalog should shed some light on things. We are certain that the letter "Z" means the indicator comes in a storage box and these are usually red in color and have spaces for you to store the other attachments. The numbering code for Starrett Last Word indicators:

  • A = universal shank PT07103A complete with long and short arm PT07104F
  • B = gooseneck shank PT07107A
  • C = all attachments included plus 3 steel (chrome plated) contact points
  • M = 0.01 mm (metric indicator)
  • P = universal friction holder with shank PT13175
  • S = most likely indicates that this is a set with some sort of attachment(s) included
  • Z = storage case
  • ? = body clamp PT07101F
  • ? = double jointed attachment PT13301
  • ? = height gage attachment PT24706 (3/16" x 11/32")
  • ? = surface gage attachment PT05119
  • ? = coupling with 3/16" hole PT05116

Because we are not Starrett distributors, you will have to get new indicators elsewhere. Amazon.com could be your best bet. Check the Amazon prices below to see if you can get a discount.

The body clamp will slip over the indicator's body with considerable friction, to keep it in place. You will then be able to clamp it to any rod between 1/8" and 1/4" in diameter, using the thumb screw. PT07101F Body Clamp Complete (includes the thumb screw) ... order on page 32

Accuracy

 

According to the manufacturer, the accuracy of the Last Word 711 indicator is ±.0005" (though this rather significant detail is omitted in the Starrett catalog).

.001" vs .0005": They're the same indicator but have different dials. The .0005" dial is simply subdivided into smaller units. Both indicators have the same accuracy. You can mentally subdivide the .001" or you can have the dial changed on your old indicator when you send it for repair.

 

Some notes about using your Last Word indicator

 

How to change the contact point: swivel the clip, which holds the contact point, using a small screw driver instead of your finger nails. Position the new contact point and swivel the clip back into place. Starrett model 711 Last Word indicators have a contact point which swivels on a ratchet. Sometimes the ratchet doesn't fit well and the contact point will cause the lever arm to jam. You'll have to try another contact point. Sometimes the pivot screw protrudes too much and rubs against the contact point. Again, try another point until one fits. For proper operation make sure the reversing lever is fully engaged up or down and that the contact point is properly seated in the ratchet. (see contact points)

How to change the crystal on the Last Word indicator: remove the chrome bezel by prying it off with a screw driver and replace the crystal (see parts list). If your old indicator still has a wire spacer, throw the wire away. The new crystals don't need this spacer. A pair of jeweler's pliers will help you squeeze the bezel back into place.

If the indicator hand jumps on a regular basis, try de-magnetizing the indicator. If you don't already have one, a small demagnetizer can be bought from most supply catalogs. Spinning objects and motors can induce magnetic fields in the indicator. If magnetic fields are a problem in your shop environment it may be best to switch to a non-magnetic indicator. Mitutoyo, Bestest, Compac and Interapid are all suitable alternatives.

If the indicator hand hangs up on occasion, just tap the indicator and the hand will probably return to its normal setting. Don't let this upset you if it happens only occasionally. We're talking Starrett here.

Repairs of the Last Word 711 indicator can be surprisingly tricky because new parts don't always fit as well as they should. You should be prepared to make minor alterations from time to time.

How old is my Last Word indicator?

 

oldLastWordbody1

The exact age can't be determined because Last Word indicators have changed very little over the years. They did, however, go through several stages with distinct characteristics. Among the oldest models you will find that the end of the body was slanted (shown above). This is probably pre-1960. Subsequent models have ends which are squared off.

LastWordolddial1

The oldest models also had dials which lacked the yellow band along the right hand side, as seen in current models. You will see .001" written as 1/1000" on the dials (shown above). Keep in mind, your indicator may have been repaired at some time and the dial may have been changed to the new style.
 



 

Q&A about the Last Word indicator

 

Q: Am I correct to assume that the hairspring is what tensions the center pinion to stop it moving and that it should be attached? On the site in the disassembly instructions it mentions there is no need to detach the spring from the center pinion yet the spring and pinion seem to be listed separately. Can they be purchased assembled? If they don’t come together how are they attached?  What is the method of installation, how much tension is put on the spring and how is it retained while assembling the rest of the indicator?

  • These are a lot of questions that require detailed instructions. Please refer to our repair manual available on page 199.

Q: I got a Starrett Last Word that was sticking, and sometimes wouldn't run through the whole range and get stuck. When I rotated the dial I found that the needle would move with the dial when it stuck. It looked like the crystal was grabbing the needle or pushing it into the dial, so I popped the crystal off (thanks for the video). With the crystal off it runs nice and smooth over the whole range. When I was trying to put the crystal back on it kept falling through the bezel and I still had the wire ring in. The indicator I'm guessing is from around the 60's, is it possible that plastic crystal may have shrunk or perhaps it was the wrong crystal on it?

  • You may be correct that an undersized crystal was in place since touching the hand is very unusual for a Last Word. The new crystals no longer need the wire ring because they have a spacer built in. Replacing it is easy and you should not have any problems.
