My painting came to a grinding halt on the weekend past.
The plastic central hole finally perished and broke in multiple places. I found out what they used as ballast - lots and lots of tiny round metal pieces. Individually I viewed them as weightless, but clearly packed into a base - weigh quite a bit.
So the painting came to a dead halt. I tried sourcing a replacement base, but no one seemed to stock any in Brisbane. When I looked online they seemed to be only (my search capability is not great) available on eBay.
Lots of friends suggested help, but in the end I had to resort to my own genius to solve the issue.
So a lump of pine (its all I had), some nails and a drill made this work. It works until I can sort out a more effective means of balancing base.
