If the shape you are thinking of is with the mandrel down the center of the bead then usually I just roll one end on a marver and let the molten glass round over on the other end.
If I want the hole to run at right angles to the tear drop then I make a sizable bead and heat it until it starts to sag and let the sag 'drip down' off the mandrel a little.
I guess there might be a bead roller for something larger than an inch and a quarter but I don't remember seeing one.
