A seven-branched candelabrum

Q: When it is not Chanukah, it is permissible to light a seven-branched candelabrum?
A: It is forbidden to make any item in the form of one of the objects in the Temple (Avodah Zarah 43a). It is possible that this candelabrum does not have the same form as the menorah in the Temple, but it does not matter since any seven-branched candelabrum would have been kosher for use in the Temple. When the Hasmoneans entered the Temple after defeating the Assyrian-Greeks, they did not have enough materials to create a beautiful menorah, so they did what they could and made a simply one. If you look into the Rambam's commentary on the Mishnah (Menachot 3:7), he has a picture with the menorah with rounds branches and not straight ones. There is a dispute whether the picture drawn by the Rambam is correct or not. Either way, it is forbidden to have a seven-branched candelabrum of any shape. There are a few solutions: 1. There is a novel ruling of our Rabbi, Ha-Rav Tzvi Yehudah, to which Ha-Rav Yitzchak Herzog (former Chief Rabbi of Israel) agreed: you should take screws and connect the candelabrum to a table or shelf, and it is thus not no longer an object. An object is something which is carried, and this is no longer something which can be carried around. 2. Add a branch. There is a famous question for Chanukah which has one hundred answers (see the book "Ner Le-Meah"): if there was enough oil for one day, then the miracle of Chanukah only occurred for seven days. Why then is Chanukah celebrated for eight days? This is called "Kushiyat Ha-Beit Yosef" (the difficulty of the Beit Yosef), since he quoted this question (Orach Chaim 670). One of the answers of Maran Ha-Rav Kook is that since it is forbidden to make an item in the form of one of the objects in the Temple, the Rabbis added a day to Chanukah or it would have been forbidden to use a chanukiyah (Mitzvah Re'eiyah, p. 84). Thus, you can add a branch. 3. You can remove a branch and you will have six.
