Message: <blockquote data-quote="Allen" data-source="post: 492243" data-attributes="member: 389">Sounds like you have the resources to be successful.Take a look online at some of the split-spoon samplers out there.  They are expensive, and probably not something you'd care to invest in.  However, I see no reason why you can't redneck something that would work fairly similarly.The basic split spoon is just a hollow tube with a cone on the business end.  That cone is designed to help retain the contents of the hole you just created.  If you are in clay, any open ended piece of pipe will allow you to remove a core from the ground.  They are just a pain to clean afterwards.  As you move up in coarseness of the material, it becomes increasingly important for the cutting edge of the split spoon to have some kind of a lip on its interior to help keep the contents from falling out as you retrieve it.  Banging it around with sand/gravel inside it is a good way to have an empty pipe when its extracted.  One can increase their odds of retaining that material by capping the pipe as it's pulled out of the ground.  This is kind of the same thing when you might sample something with a straw where you just dip the straw in the drink, then put your thumb over the top end of the straw and hurriedly get the bottom to your lips.  As for the cutting edge with a lip?  You might be able to just buy an extra connection fitting, then take and weld a thick bead all the way around the interior on the bottom end.  That should give a person a little better of a chance of retaining the core. To clean it out, a garden hose works well.  Just shove the hose in the pipe and turn the water on full blast and let it erode the stuff out of your pipe, keep shoving on the hose so it is always blasting directly onto the material in the pipe.  Another option is to lift it vertical and get busy on that pipe with a big hammer as the dirt can really get compacted in there.  This is the method I suggest if you are also looking for a little exercise and a lesson in patience.</blockquote>
