24-Mar-10 Once again I have to thank the generosity of others to have the right tool when needed. Here we are trimming the fire pan width to fit the actual boiler width. Although the pan is clamped down to the table, a conventional right-hand cutting tool would pull the sheet metal up and chatter mercilessly. But I was given a left-hand spiral cutter, which pushes the metal away from the cutter, or onto the table in this case, resulting in a rock solid, noise free cut.
