It was a present for my sister-in-law's garden and I only had one afternoon to play with it after cracking it open. I'm guessing around 200lbs.Borishttp://www.blogger.com/profile/13965125392095147170noreply@blogger.comtag:blogger.com,1999:blog-3040363452505236063.post-82083894841532751832008-09-13T19:17:00.000-05:002008-09-13T19:17:00.000-05:00How much does the stone pictured weigh?Alexhttp://www.blogger.com/profile/09850828910653998528noreply@blogger.comtag:blogger.com,1999:blog-3040363452505236063.post-18301872774855153682008-09-08T07:05:00.000-05:002008-09-08T07:05:00.000-05:00Great post and superb explanation.<BR/>I've been going to make on of these babies for a while.<BR/><BR/>Cheers<BR/>Robpower athletehttp://www.blogger.com/profile/04235126663171014531noreply@blogger.com
