Thanks for your quick reply. Currently i am using a 1300C jet lighet i bought from dealextreme. Do you think it will work if i cut the mesh in a circular pattern with a small wire cutter and then remove the remaining bit with a small plier? That was my initial approach, but then i read about the screw. By the way the metal plate i intact, i just poked it a bit through the hole just to clarify if there was a barrier between the nipple and the mesh. Do you think it will be sufficient if i just remove it the way i mentioned, and then torch it for about 1 min with the Jet lighter for DX?
