I'm still actively working on this project, but I'm not going to be finished by the current deadline (tomorrow). It seems I underestimated how much work was involved. I need to drill a few more holes, weld some plates onto the tabletop, weld the legs onto the plates, and then finally weld tabs onto the frame to hold the wooden panels.
Is it possible to extend the project deadline by a month to 25 June? I think this should be enough time to get it finished.
For info on the current state, I have uploaded a picture of the work in progress (legs are laid up and will be welded soon, but can be detached by unbolting to flat pack)
