jimbobs ....... ... I just posted a question to you on that other Thread before realising you had this Thread started .
I was asking this --- I hadn't realised how the beams had been attached to the concrete uprights . But I had to dig out an old photo and this is what I see ........
I hadn't known they attached short verticals about 300mm long using a couple of bolts.
Can I safely take off those short verticals and bolt into place new verticals 1500mm long ? With maybe a bit of bracing ?
The replacement roof will be much lighter.
