Emmmmmm No. Mainly 80 x 80 Aluminum Profile Doubled up in some areas and 16mm Aluminum Gantry Plates. Solid as a house as it has no problem with me walking about on top of it. I have a few bits to finish off and the odd tweak to make. The biggest problem I have is space. She takes up so much room in the garage that she is almost unusable as it is now near impossible to get 2.4m x 1.2m sheets in. Shes a big girl !!! 2.8x1.5 footprint give or take. Hence she has been idle for 2 years!
