If I remember correctly the "Cetme" has many curve surfaces. Getting the radius of each surface to align correctly is a problem that is hard to solve without the dies and press to bend it. Many of us have made the AK receiver well enough to work but it has four flat sides and can be realigned with a large hammer and bucking bar. There is a world of difference in what allowable slop between these two rifles. After bending up the flat you must "Heat Treat" spacific part of the flat. The list goes on of things that must be done inorder to have a rifle that is safe to fire. If you have no experiance in working with an annealed spring steel I would recommend buying five flats, at least, or buying an already bent, heat treated and numbered, but unfinished receiver from someone who advertises in a publication like "Shotgun News".
It is a lot of work to make something as simple as the AK, bending the "Cetme" is a step or two above.
