Having measured the remaining stock of 5mm x 3mm slotted 'T' section I was pleased to find my calculation for the original order was just enough for the 8 pieces required for the top and bottom parts of the short 19ft girders. It did mean that 3 pieces would formed from off cuts - two per girder which is better than purchasing more 
.
The wall end of each of the four 19ft girders will have downward extensions to form the wall fixings. During fabrication I soldered a 2mm x 0.5mm piece into a cut in the slot at one end of each girder so it extended upwards and downwards to enable me to make sure the proposed wall fixing was in the correct orientation before cutting of the top piece.
So far the middle verticals and diagonals have been soldered into position in the slot using 179 solder cream with an RSU - the girders now await delivery of the 'T' section brass in order to complete the build.
