This is the same pamphlet that my buddies and I ordered from an ad in the back
of Popular Mechanics about 30 years ago.....

Their design is meant to be built as a static test model that an amateur
rocket engine builder could make with simple machine tools and commonly
available materials (No, we never actually built one).

It was never meant to leave the ground. The engine is too heavy and depends on
a complex set of ground support equipment. The oxidizer is gaseous oxygen from
a welder's tank. The engine depends on a steady supply of cooling water to
keep it at a safe temperature. The pamphlet states (on page 22) that a
flight-worthy engine would need to be built from exotic materials that would
be difficult to fabricate in an amateur shop. 

This would be a great project for someone to learn fundamentals of rocket
design, but it is not a flight-worthy propulsion system for a satellite or a
launch vehicle. It is a first step but designing a flight-worthy engine would
take a major effort beyond what is in this pamphlet. Designing a launch
vehicle around that engine is even more of a stretch.

I hesitate to say that something is impossible but building a rocket to reach
orbital velocity with amateur resources seems to be of such a magnitude that
there must be a more productive way to spend the remaining years of one's
life.
