I am based in Centurion.. Pretoria Midrand . The Play sand Kitty litter sand and plaster sand are all good but if I can source some of the Chrome sand I would be very happy because as you say, if you are going to make a success of a project then give it all youve got and get the best you can.I must admit that the stand I built is very over the top and over "built" with infinitely adjustable spikes on 75 mm legs reinforced with 100mm flat bar etc etc If someone can help with REAL sand a big thanks from me.
