Was it you that I referred to my colleague Joe worked at Space-X and flies
N2O hybrids and if so did you connect with Joe?

Awhile back I asked this forum if anyone here has information on nitrous
oxide hybrids, and from all the info there and other info I have found just
about enough info to get an idea for the general design of my engine, which
will be gaseous nitrous oxide fed through a showerhead style injector into
a tube of moulded paraffin carbon black mixture, out through a standard
nozzle. If it works, I would like to try and create a UC valve type
injector, which uses ACPC fuel grain on an E Match to light the fuel and in
the process release the oxidizer flow, which may be as simple as plugging
up the oxidizer hole, or having a small pinhole be able to vent enough
oxidizer to sustain combustion.
What i'm mostly curious about is the actual design and manufacturing of
the engine, as this other forum I have grabbed info from is mainly pushing
me to buy commercial rocket casings and parts, however given I think I have
access to all the tools I need to make a full motor, i'm hesitant to spend
more money than I need on parts I could just make myself. I also honestly
just want the fun of designing and creating everything from scratch.
So, that being said. How do people manufacture hybrids? I've heard
graphite as a nozzle is effective, however it's also extremely porous, and
I'm hesitant to use it as a unibody design for the main combustion chamber
and injector. I would very much like it if someone here who has either
built their own or knows of any detailed papers telling of the
manufacturing of the body of the motor. I know of Nakka, and that will be
extremely useful to start manufacturing once I have the ability to get back
into my school's shop.
Thanks!
