SKATEBOARD WHEELS MAKING FAILED SCIENCE RESEARCH (UPDATED)

[@RonaldsMazitis]

The expenses - one time silicon mold should not be that much expensive about 20 dollars. (You could fck up the process, so it might take more money). Pressure pot for 150 to 250 dollars. One time expanse, together from 200 to 300 dollars. So actual cost of the wheels - Polyurethane liquid casting rubber Shore A 60 (Poly 75-60 - 2 kilograms, 31 dollars. 2 kilograms of resin probably would provide like atleast 4 wheel sets. Making a set of wheels cost 7 dollars each. (Without cost of equipment).

make ammonia from natural resources extract nitrogen from it and to alkylation to it to get amines

What's not explained in raw version on KZbin? How to make silicon rubber liquid from natural resources. How to make polyol from castor oil. How to make isocyanates from amines reacting with phosgene. How to make amines outta biomass. How to make phosgene outta gasification of biomass. Mixing it all together to create uretathane liquid. No explanation what would be DIY version of PVC plastic pipe or pot. No explanation over DIY pressure pump. And pressure gauges DIY would be scify.
