I made some up with 125mm centers top and bottom. I got the size by scaling off drawings. I know the top ones seemed slightly shorter but I put that down to the fact that I was not looking at a true length on a flat drawing. I used flat bar for now and plan to remake them using 12mm stainless steel hydraulic tube.
Just about to leave for Arnhem, third camping weekend in a row. Netley Marsh, Vierhouten and this weekend Oosterbeek. Poor Linda, all alone for the whole weekend.
