Help replacing broken leadscrew (2015 First Choice item)

[buchanan]

In an off season event today we snapped (!) one of four matching leadscrews on our robot's stacker. The screw was an AndyMark First Choice 2015 item (http://firstchoicebyandymark.com/fc15-020) but isn' t available through them now. Does anyone happen to have one lying around they'd be willing to part with for fair market value?

We're not really interested in re-engineering for different or non-matching hardware since this machine has only one more off season event scheduled before being put out to exhibition-only pasture.

We have spoken to the manufacturer (Haydon Kerk), and they don't sell small scale, but directed us to McMaster-Carr. MMC does have matching material, but only in 72 inch lengths (we need 18") at $157, again kind of steep for an about-to-be-retired robot. That will be the fallback plan, though. We can always salt the rest away for possible future use.
