To all interested While on this subject of using steel if there is any sharp bending to be done it could be of some advantage to know the rolling direction of the plate. Sharp bends 90° to the rolling direction can cause fractures of the steel. Particularly on harder sorts. Whereas bending across

I, too, have heard the warnings about stress deformations in cold-rolled. But I wonder if it makes any difference in this scale. I've seen loco frames made of brass -- much softer than steel -- which were quite rigid once they were stayed with three or four cross- members. I feel like steel sho

Hi Harry, I'm surprised to see that you still get mild steels with the mill scale still on it. Nearly all the steel plate in the part of Europe where I live is sandblasted. The reason is that the mill scale inhibits good flame and Laser cutting. Added to this, mill scale is very much of a problem
