Using stainless steel for a firewall does seem logical as CG mentions. Today I spent some time working near the firewall on my 14-19-3. Had my magnetic flashlight close by and before I knew it the magnet was stuck hard and fast to the firewall. Knowing that most stainless does not attract a magnet I must now assume that the firewall is some plain vanilla sheet metal. Does this sound right? Can anyone else confirm this? Thanks, Rob
