I did some local investigating and came up with the following information, do you think they would be suitable with the two inch flats at that thickness or should i get it a bit thicker.....BTW to convert theses to $US roughly half these prices:
WE HAVE A 200MM DIA BALL MADE FROM 0.9MM S/S. IT HAS A 50MM FLAT AT THE
POLES AND A 6MM FLANGE AROUND THE RIM TO WELD TOGETHER.
A COMPLETE BALL IS $110.00 + GST.(WELDED AND POLISHED) 2 WEEK DELIVERY
TIME.
YOU CAN ORDER THE HALVES OFF THE SHELF (NOT WELDED) FOR $17.50 + GST.
