These are always interesting posts.
for the original poster.
welcome to the forum! Lots of good information here, and I wish you well in your rocketry endeavors.
in your very first post here, you ask about home made rocket motors. As you have seen online, there is plenty of information on them, but the materials are difficult to get in some places and the risks for experienced rocketeers are low but not negligible, the risks to inexperienced rocketeers is high.
I don’t think it makes sense for anyone to consider doing it until they have considerable experience in flying standard rockets. You may have a lot of experience with these, I can’t tell from the limited information you have provided. As a minimum, you should likely have successfully dealt with reloadable rocket motors before you start building your own.
what is your goal? If it is the challenge of building and launching and recovering a rocket from scratch, including the motor, you might consider water rockets. These literally started as a child’s toy (I had one as a kid.) people have been messing with them for a while, and currently they range from still simple to pretty darn challenging, including staging. You not only will need to build the rocket and the nozzle, you will need to build the filling system, “firing” apparatus, and launch tower. A brief google search says the world record for altitude is 830 meters. I have seen many if the YouTube videos, and the water rocketeers look like they are having a lot of fun.

last I checked, water is relatively abundant and not heavily regulated in Norway.
So if it is your craftsmanship and engineering skills you want to develop, there are other options .
in any case, if at all possible, it is a good idea to meet with and fly with some rocketeers experienced with what you want to do before committing your time and effort into anything. 95% of my rockets are scratch builds (but I use commercial motors), but I built 10 or 20 kits before I started on my creative kick to “learn the ropes.” Working with experienced rocketeers will reduce the amount of time you spend “reinventing the wheel.”
as
@prfesser said
Making rocket motors has a learning curve that is likely to cost you...not just chemicals and parts, but also destroyed rockets.
what he didn’t specify is that the “parts” it may cost you include fingers and eyes.
I agree with
@Troy3003 ,
If he learns how to do it safely, then where is the issue?
key word is “safely.” IMO (humble or not) “learning safely” involves doing it after discussion with and under direct supervision of someone who has already DONE it successfully, something you can’t get from seeing any number of YouTube videos.
i wish you many safe and successful flights and recoveries, and I hope you have a great time doing so. I will refrain from wishing you have a blast!
