Mori make a slick machine. Not quite as slick as a Roeders though. 43K rpm
spindle and good to a micron. I’m contemplating installing a laser module in it
if the manufacturer will sign off on it.

Not sure what size you'd need but I've been drooling over this one lately:

It's a combination 3d printer and a vertical milling machine.

All the printers that are available to print chambers. SpaceX and
Boeing aren't going to rent you time on theirs. Maybe EOS has
dramatically increased their production rate, and my math is out of
date. If so, it has done surprisingly little to the price of prints.
How many chambers does Ursa make at a time or per year? Rocketlab hit
their 100th engine less than six months ago, and they're one of the
larger consumers of printed chambers.

Are you saying all the metal printers in the world can only make about 468 5k
thrust chambers per year? I disagree.

It’s a fairly quick bit of math to find that the launch rate of an
expendable system with printed thrust chambers ends up being constrained by
the total number of printers in existence in the world (and really, by the
number of printers you can use within the artificial constraints of it*r).
That number is about one rocket’s worth of chambers per week. Distributed
across the four or five significantly capitalized companies that are doing
printed thrust chambers.

With high value payloads perhaps. That seems like an expensive logistics
operation added to small and expensive launch system. Just an opinion but
perhaps focusing on designing and producing an inexpensive, simple and
reliable booster in vehicles this size and forgoing recovery would make more
sense from an operational cost standpoint. Or perhaps not. A few successful
missions should confirm it either way.

Electron is going to try it and it's something that's been done in the past.

Someone I have known for a long time asked me about using a remotely

It is a topic about which I don't know enough even to be dangerous.
But I said I would try to find someone who knew enough to critique his
ideas.
If there is such a person on this list, and you are interested, I can
pass on this guy's email.
