When I tlaked to Jim at Questar, he said a couple of months, but he also said he was having trouble finding machinists that can work with a typical lathe, mill, and drill press. He said all the kids coming out of school only know how to program CNC machines, which doesn’t work for Questar because CNCs are prohibitively expensive. Typically they start around $20k from what I’ve seen.
With all due respect to Jim, who seems like a nice guy, but that's ridiculous. Drill press?!?! It's insanely cheaper to make most parts, even in small batches, on CNC mills & lathes. Modern CAD/CAM makes programming far easier & better, and the machines will outperform any human machinist that ever lived (including my father, whose mid-60s Machinery's Handbook I inherited years ago) in part-to-part consistency, speed, and probably even absolute accuracy.
FWIW, a small "real" vertical mill like a Haas Mini Mill (which would make mincemeat of most of the parts in a Tristand) is around $35k new last time I looked--but no one pays cash for these machines as it's a terrible use of capital. They are usually leased or financed, and parts cost is computed on a machine time basis. If you figure your little robot buddy will last 5 years, that means you only need to cover $7k/year plus tooling, power, and shop floor space. Your expensive machinist can devote their time to programming & setup and leave the parts loading, swarf removal, deburring, etc. to assistants.
I offer as proof the Losmandy GM8, which is a much more involved product made in the USA of machined aluminum. The non-goto versions sold for only $300 or so more than a Tristand, and I never heard anyone criticize Hollywood General Machining's workmanship (nor seen anything to criticize in person).
If part of the appeal of these devices is Old World Craftsmanship, cool--but please let's be honest about it.
Just my opinion.
