Nothing I have seen anywhere is close to being big enough for the 24. I will get my last one out tomorrow and take some measurements. It needs to be fairly heavy because it is the spinning mass weight that makes these machines so good.
Don't stress about getting the bases out, in no rush. I probably have 50 here, I just have to repair and paint up another batch before the weather turns bad.
I haven't bought any bushes because I have a small supply of bushes left but can never have too many
