Tool time Tuesday and today we’re wrenching some stuff.  Over the weekend I helped my father in-law Larry work on his log splitter.  It was being a bit finicky the last time we used it.  Actually, it stopped working completely.  A bit of trouble shooting and we went about checking and cleaning a couple of filters.  One of those filters, the inlet filter to be exact, is threaded into the hydraulic fluid reservoir.  We used a pipe wrench to remove that filter.  When I say pipe wrench, most of you probably have a picture in your mind of what it looks like.  That design is actually called a Stillson-Pattern wrench, so named for the patent holder, Daniel C. Stillson.  Stillson received his patent in October of 1869.    In August of 1888, the Swedish inventor Johan Johansson improved on the design and receive a Swedish patent.  The pipe wrench is designed to loosen or tighten threaded pipe but is also handy with removing a hex nut that is rounded off.  The serrated teeth in the adjustable jaws dig into whatever your working with, giving you the grip you need to get the job done.  We got the job done using a ten inch pipe wrench.  Listen to the podcast here;
