Starrett 711 Last Word Indicator

 

Your grand-dad probably had one of these. Maybe he even passed it down to you and you'd like to have it refurbished. Long Island Indicator Service has been repairing these stalwarts of the American shop for decades and because the parts haven't changed substantially in all these years, even old Last Word Indicators can be returned to "like new" condition. Check our repair service for details.

Accuracy

 

According to the manufacturer, the accuracy of the Last Word 711 indicator is ±.0005" (though this rather significant detail is omited 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: 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. Bestest, Compac and Interapid are all suitable alternatives.

Repair it yourself

 

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.

To do a satisfactory repair you'll need a pair of fine point tweezers, a small and a large screw driver, small jeweler's pliers, hand lifter, a loupe (or magnifying glass), de-magnetizer, cleaning solution (your choice), and lubricating oil.

Begin by completely disassembling the indicator. This is the only way you can examine each part and determine what needs replacing.

Remove the large cover screw on the side of the body. Remove the large cover screw on the end of the body (or the holder which may have been placed there). Remove the contact point (see instructions above) and unscrew the pivot screw. The lever assembly now slides out of the body. Remove the bezel (see instructions above) and the clear plastic crystal. Now you'll have to get the hand off and for this you'll want to use a hand lifter. You can improvise using two flat bladed screw drivers, but beware, you're likely to break the pinion if you're not careful. Remove the two screws which are revealed under the dial. Lift off the plate, the wavy washer and the ring. You're left looking at the hair spring attached to the spiral gear (center pinion). Notice that the hair spring is pegged into the body with a small brass pin. Push this pin out from the inside of the body. It can be tricky. When complete, remove the spiral gear, but there's no need to separate it from the hair spring. Leave these intact. Congratulations! Your disassembly is complete.

Clean all the parts by soaking them in a cleaning solution of your choice and then brushing them clean with a soft brush. Take extra care not to harm the hair spring. We like to use the mildest solution that will work, starting with an organic cleaner and moving up to a petroleum product if the grease and oils won't dissolve. It's imperative that all parts are immaculately clean and dry. If rust is present, now is the time to take out the wire brush and sand paper.

As you reassemble in reverse order, you'll want to examine each part for damage and replace those with new parts. There's little chance that any part can be repaired, so you'll save time and effort by keeping a small stock of commonly used parts at hand. Use a tiny amount of oil on moving parts and don't forget to demagnetize these indicators when done. It can make all the difference.

On page 73 you'll find a parts breakdown to make identification easier.

There's quite a bit of satisfaction to be had upon the successful repair of one of these indicators, so enjoy!
