    I am planning to make a cylindrical post with a spherical head and i want
to be fabricated it either on PMMA or on silicon. I have gone through few papers
which state how to fabricate the cylindrical post but iam unable get papers on
how to get the spherical head. If any does know about any papers or how to
fabricate it I would really appriciate for their help. I would like to thank you
guys in advance.

Thanks,
Dhanam
