  • Spiral Worm Gear Stock

    Are short lengths of spiral worm gear stock available from vendors at prices
    mortals can afford?

    Desired is a length of gear as follows:
    7/8" OD (3/4" PD), Left Hand Spiral, 45؛ Helix, 16 Pitch 12 tooth, (22.63 Normal Pitch)

    If these dimensions are somewhat nonsensical, it is because I am reading from a print
    and do not know better.

    If it also came with a 3/8" reamed ID and a 1/16 x 1/16 keyway, I would be
    moved to buy lottery tickets.

    Are you matching a gear or do you have some flexibility in the design?

    The reason I'm asking is some bolt houses near you stock ACME all thread. LH ACME all thread may be available by way of special order if you ask a knowledgeable counter sales person.

    For instance, the counter guys at Nisku Nut & Bolt seemed pretty good when I went there in July.
    Design to 0.0001", measure to 1/32", cut with an axe, grind to fit
