Ariel,
may I suggest to modify the Wiki about the hybrid base?
As I discovered few minutes ago, before screwing the rebuildable part on the hybrid base, you have to remove the center post extension.
Of course, any suggestion and help is very appreciated
Let me see if I understood what you mean:
you have to remove the center post extension (used for the 510 base) from the rebuildable part and replace it with the center post extension of the hybrid base.
Something like this? :
1.- Unscrew the Tilemahos rebuildable assembly from the 510 base.
2.- Replace the center post with the one included with the hybrid base.
3.- Screw the hybrid base to Esterigon.
4.- Screw the rebuildable part until it stops.
5.- Assemble Tilemahos as usual.
