answers for all questions I found in attached pdf :)
sorry :)

and salute!

In attachment I put some idea about mandrel and finished piece for displacer chamber with flange. I don't know is it taper of side walls necessary. this is link: http://www.stanford.edu/group/prl/documents/pdf/spinning.pdf they say that austenitic stainless steel 201 and 301 are very good for spinni...

Hy people

Is it anybody try to spin stailess steel metal sheet (for example tickness 0.5mm) to produce displacer / displacer chamber

Salute Ante!

I found this page

http://www.bekkoame.ne.jp/~khirata/english/mk_rot.htm

it seams to me like very compact design

please comment.

My advice is if you measure (feel) high temperature on the top of can after short time of heating try to f...

Ante, My neighbour and myself are working on a similar thing. Goal is to have this thing working before mid june. We're planning to use a electromotor but this is a very simpel and elegant and clever solution. Why didn't I think of that myself, using a stirling to rotate the pig. Question : what ty...
