I need about 30 feet of rack gear (2x12' + 1x6', or 5x6' which seems to
be what's actually available) and 3 spur gears for a project (upgrading
my old cable-drive CNC (woodoworking) router to gear drive). More
expensive, fancier options are relegated to fantasy, I think. I did
consider things like Acme screw drives, but the increased rotating mass
seems like a problem, as is the flopping length of the 12 foot longer
axis. Ballscrews are a post-lottery-winning option only, I think.

Of MSC and McMaster, McMaster is a bit cheaper for this item.

I suspect that for the limited purchase size they may be the only
sensible option, but thought I'd throw it out here to ask if there are
any other suppliers friendly to HSM/small orders that might have better
prices.

we use a place called union iron for building rack & pinion slide gates..
quite a bit cheaper than McMC
here's a number
