According to the custom of lighting a shamash for the menorah, must it be set at a different height from the rest of the lights of the menorah? While the common practice these days is it's taller, the shamash can be lower to meet the same rule.
My question is regarding how that height difference is accomplished.
Can you simply use candles of different lengths to accomplish the rule of keeping the shamash at a different height? Meaning you either use a taller candle for the shamash or if all candles are the same height you cut one shorter to meet the same rule.
Would this work according to this custom or does the menorah itself need to be designed in such a way where the shamash is either higher or shorter? As in the metal candle holder itself is at a different height from the others by design?
