Hi Fuzz, when the time comes , if i,m able i,ll come up and give you a hand. I wonder would next years rhayader be too late as we,d have to be there for 2 days. one day for concrete and next day to fix it on. That no nails stuff is a bit dated now, there are modern type polymer adhesives that will even stick under water. got plenty here and chippings and cement etc.
