Hi BB,
Yes it got done by either the local council who were the first owners, or the owner before me who had owned it for the past 20 years.
Looks like the rails have totally failed, and then they have pulled the rails back together. Put some flat bar on the long sides of the front and back rail, then put some round bar on the inside of the side side of the rail.
I have to change them and will look at doing it in the next few days. I can now see why these 20" 45 twin rails are very prone to cracking with all the twist and vibration from the engine. You can really see this when you start an engine on the bench which isn't bolted down. It takes a lot of effort to stop the engine jumping and rocking about, so the 3mm pressed steel rails would just have too much give and flex in them.
This is why I am hoping the modified 3mm RHS will be more solid. I should have maybe gone for a slightly thicker RHS but I think it should be okay for a good few years anyway. I think I will also put some flat bar between the rails like KenW did, as that will brace the rails as well.
