The New Hotness

  • Tea Ball Revival

    The latch closing my tea ball consists of a nice stainless steel dingus held on by a grotty rivet of unknown provenance that I’ve repeatedly staked over the years. It finally came undone this morning, so I had a few minutes of Quality Shop Time right after breakfast.

    My tiny-screw box (left over from the long-gone Leichtung Workshops) has some stainless 0-80 screws that I found somewhere, but only brass nuts. Ah, well, we used to use brass water fixtures and lead pipe, so an 0-80 nut in hot water isn’t going to kill me.

    The ball rim has a recess for the rivet head, but the screw head was slightly larger. I braced the rim of the ball across the vise jaws and give the recess a few shots with a fat punch to enlarge it.

    Then…

    • A dot of Loctite on the threads
    • Assemble everything
    • Take it apart to put the latch on the correct side of the rim
    • Reassemble
    • Attempt to close
    • Gently bend the rim to flatten it out
    • Close
    • Attempt to latch
    • Brace closed rim on vise opening with screw head up
    • A few shots with a drift punch to settle recess around screw head
    • Success!

    It seems I ain’t worth a damn in the morning without a hot cuppa. The rituals must be preserved.

    I tossed the ball in the dishwasher and opted for a tea bag today…
