I am trying to find a source, preferably in Canada, for small quantities to build model steam locomotives. Must have a wall thickness of 0.11″ to 0.125″. 28 Nov 2000 at 2:25 pm #288966 fourth yearParticipant Yes it is made. Type “M” has a wall of .109, type “L” is .125, and type “K” is .160 Author Posts Viewing 1 reply thread You must be logged in to reply to this topic.
