making a bridge on a sledge ?
i know thats a wierd title but i have an explanation. i reckon its going to snow soon and to get to the best hill me and my freinds have to cross a frozen stream about a foot wide but 6 foot at the top of the v shape its in we cant jump like we would any other time of year because of the sledges weight we couldnt get far enough and we`d land on the stream and get very cold. so is there any way that anyone can suggest of atatching a bridge to my sledge (a bit like the mt 72 tank principle). four main criteria are:lightweight ,removable,cheap and 3 foot long(the sledge is already three of the six foot) i have an idea but its heavy.the sledge is wooden and has an 8inch by 3 foot space underneath and is about a foot off the ground.all ideas are welcome! please help.thanks ,wood wizard.
i have limited wood can anyone suggest a design where the bit of the sledge where you sit becomes part of the walkway. also im getting two of the desgns ive thought of on my site : http://my-site-me.webs.com/
