When [Morley Kert] laid eyes on a working time card-punching clock, he knew he needed to have it for a still-secret upcoming venture. The clock appeared to work advantageous, besides that after a dozen or so take a look at punches, the ink was quickly fading away into illegibility. After a brief teardown and inspection, [Morley] decided that the ribbon merely wasn’t advancing because it ought to.
This clock makes use of a ribbon cassette akin to a contemporary typewriter, besides that as an alternative of a feed spool and a take-up spool, it has a brief size of ribbon that goes round and round, getting re-inked as soon as per revolution.
When a card is inserted, a lot of issues occur: a brand new gap is punched on the left facet, and an arm pushes the cardboard towards the ribbon, which is in flip pushed towards the mechanical digit dials of the clock to stamp the cardboard.
Lastly, the ribbon will get superior. Or it’s purported to, anyway. [Morley] may simply see the shadow of a chunk that was now not there, a spherical piece with tooth with a protrusion on each faces for participating each the time clock itself and the ribbon cassette. A easy little gear.
After emailing the corporate, it seems they need $95 + tax to exchange the half. [Morley] simply laughed and fired up Fusion 360, having solely caliper measurements and three seconds of a teardown video exhibiting the lacking half to go on. However he pulled it off, and fairly rapidly, too. Model one had its issues, however 2.0 was an ideal match, and the clock is punching evenly once more. Make sure you test it out after the break.
Okay, so possibly you don’t have a time card clock to repair. However absolutely you’ve needed to throw out an in any other case completely good coat as a result of the zipper broke?
Thanks for the tip, [Zane]!
