I recently gained access to some old farm lands that has numerous creek beds with exposed sandstone on the property. The rock in these creek beds is consistent in thickness with the length and width being some what semi consistent. There are also several old sand stone retaining walls where much larger rock appears to have been cut to a uniform size prior to their construction. Some of these walls are expansive and contain tens of thousands of pieces of rock and must have taken quite a long time to build. I have found one rock that is about six foot long and its shape perfectly matches the outline of the state of Kentucky. A neighbors daughter who worked for a landscape design company in college tells me this type of sand stone would be very well suited for landscaping, pavers and wall building. She commented that the Kentucky shaped rock would go for top dollar to the right person. One of our local building contractors told me a lot more rock is now being used in housing construction than what it was thirty years ago. I am considering the possibility of collecting and categorizing this rock in an effort to make it available to landscapers and stone masons. I have also given thought to building a cutter heavy enough to split the larger sand stone into uniform pieces. Does anyone have any advice as to the proper place to start? I have checked with one landscape material supply yard and they work strictly on a consignment basis. Is sales by consignment a common thing when dealing with such supply yards? What would be the pros versus the cons of dealing strictly by consignment?
