Rustam - there isn't any info on stock making, but the author does recommend a book that can help. There is however a section on building a slow ( rust ) blueing setup !

No barrelmaking I'm afraid - this is a subject you will struggle to find useful info on. An American chap called Bill Holmes apparently details building a simple rifling setup in a book called " The Home Workshop 9mm Submachinegun " - I don't have this book though.
There are drawings for making hook rifling cutters in " DIY Machinegun " by Gerard Metral but I don't think they would scale down to .22 <img src="http://jsramsbottom.co.uk/bbs/e/icon_frown.gif" alt="Frown" width="15" height="15"><!--graemlin:-->
Finally there is a video and plan package available from the USA showing the construction of a rifling machine - pretty expensive if I remember - about $200.
