Well I am planning on making a slider, and need to know how to anchor it. It will be in shallow water and in soft mud. I dont want to make it float. So how do I go about securing it.

anchor the posts into the mud and then use 2x4s at 90 degree angles to secure the posts.

Use 4x4s for the main posts. Cut a point into the end, pound the posts in as far as you can, then cut the post to the right height (which will also remove the mushroomed over top) <BR> <BR>Include diagonal braces from post to post to help stabilize the structure.

Clarke, <BR> <BR>4x4's for the main posts <BR>2x4's along the side to tie all 4x4's together <BR>2x8 across the top to complete the slider &amp; seal everything together <BR>Landscape / lawn bender board for the top ( cheap / easy material to use ) <BR> <BR> <BR>* for side braces 2x4's as Rod said. Also depending how tall the slider is we used 8 foot landscape / tree stakes &amp; drove them in 5 + feet to provide extra support to the 4x4's - its solid as a rock. <BR> <BR> <BR>Here's the basics. <BR> <BR> <BR> <BR><img src="http://www.wakeworld.com/MB/Discus/messages/65919/371845.jpg" alt="Upload">

Thanks. how hard is it to get those in the ground? Just a sledge hammer will do?

soft mud? yes a small sledge hammer will work. if you have a post driver it works way better..

next q <BR>whats the legalities on public water ways?

where do you want to put it?

yeah but where the heck do you get the post drivers at?

In a river. back in a creek.
