It seems that there are no others, so now it is up to you to figure it out and take some picture so we can have it as a Techtip smile Around here, when you can make it up, you can build it, just use lots of twine and barbwire to hold it together grin I know, us farmers keep everything going that way.
Good luck and if... keep us posted, not all members here have the knowledge or vision to make changes like that.
