I had to disassemble the burners on my stove because the thermocouple on one has gone and it's the only way to get the top plate off. (Force 10 stove, Sabaf burners) The burners are two-piece aluminum castings held together with thin stainless screws, I reckon about 3/4mm. Inevitably, the screws have seized into the castings and have snapped off. I need to drill them out and replace with slightly oversize bolts and nuts but it's proving difficult to drill the bolts out as the drill flexes and wanders off the bolt into the much softer aluminum, even using a drill press. Any tips on how best to drill these bolts out of the alloy?
