Some Castle sets have pins and holes. How do they snap together?
From David Eaton: ! The castle sets with technic pin connections are: • 6034 Black Monarch s Ghost (Black) • 6040 Blacksmith Shop (Grey) • 6041 Armor Shop (Grey) • 6059 Knight s Stronghold (Black) • 6061 Seige Tower (Grey) • 6062 Battering Ram (Grey) • 6067/10000 Guarded Inn (Grey) • 6073 Knight s Castle (Grey) • 6074 Black Falcon s Fortress (Grey) • 6080 King s Castle (Grey) • 6081 King s Mountain Fortress (Grey) • 6085 Black Monarch s Castle (Black)However, 6034 has a clip on the side making it incapable of actually connecting to another castle wall section on one side, and also has a wall that is one stud and one plate lower than the other segmented sets. 6081 is wierder. It s only got 1 peg hole, and what s more, the battlements where it connects is 2 bricks and 1 plate too short. Very odd. 6074 is unusual in that it has four holes for connection.
