similar or same? can they be mixed (both ways)?
and for the "pelvis": is that a double length pinhole? with middle stop for pins? as far as I can see from the sets using it, its supposed to be used with a 12T bevel gear
--> if the partial gear from the top is a 20T gear, are the teeth aligned or shifted one half tooth to be inline with the bevel?
