Caro Lu�s,

I am glad to hear from you again,

>Let C1 and C2 be two exterior circles with centers
>O1 and O2 and radii R1 and R2. Determine the locus
>of the centers of the circles that cut C1 and C2
>with antipode points.

This is a basic fact that appears as a corollary in Julius Petersen's
great work

M�thodes et th�ories pour la r�solution des probl�mes de
constructions g�om�triques (1880)

This corollary can be seen in page 13 of my paper

and problem 52 at

Best regards,

Francisco Javier Garc�a Capit�n
