Silhouette Eyeglasses: Second Temple Repair

As we expected, the remaining temple of Mary’s Silhouette glasses broke, a bit over a year from the previous repair, and this repair proceeded along the same lines as the previous fix.

Cross-drill a brass tube for the teeny screws:

I don’t recall having to do quite this much filing to make the screws fit, but they don’t call ’em “needle files” for nothin’:

Trim the tube to the proper length by chucking it in the Sherline, rotating the spindle by hand, and filing a notch just below the jaws:

Then file the end flat, countersink it just a bit, and ream out the hole to fit the broken end of the earpiece. This one didn’t quite fit the tubing, but we’re talking a few mils of tolerance on a bent piece of titanium. Rough up the end of the earpiece, degrease everything, and a few dabs of epoxy suffice for another Steampunk repair:

The original fix continues to hold, but … this can’t go on.

  1. I’ve been using one brand of Ti frames (allergic to nickel and stainless), but they’ve gotten so damned fragile and very fussy about lens sizing. I suspect my next pair of glasses will be plastic frames. Maybe go for the Barry Goldwater look. [grin]

    Is that Parafilm on the lens? Looks handy.

    1. very fussy about lens sizing

      My most recent glasses came from Zenni Optical, mostly because they have taller lenses that seem better suited to progressive correction curvatures. So far, so good.

      I like the Silhouette zero-frame concept, but it’s way too fragile for me.

      Is that Parafilm on the lens?

      Got it in one. Sticks to itself like glue, doesn’t leave anything on the lens, and repels damage like armor: can’t be beat!

  2. So, why the groove and parting off on the Sherline rather than the lathe?

    1. I was turning the chuck by hand while filing; it was pretty much a manual operation.

      Not to mention the lathe’s ancient three-jaw chuck can’t grip anything that small…
