•  When your Dremel rotary tool’s sanding drum gets clogged, refresh the surface with a rubber pencil eraser. Run the tool at low speed and press the eraser into the clogged drum to rub out the chips and gunk.  I never thought of this, but I do have something similar to what I use for my bench sander that I use.  
  
• To clean out the sandpaper in a bench sander, press a pencil eraser into the sandpaper as it goes around, to  help clean out the paper and extends the life of the sandpaper. 
  
• You don’t always have to throw away tools that may be broken. You can change them to make them usable again.  For example, if you have  Phillips screwdriver where the parts have broken off the end. Since it cannot be used anymore as a screwdriver, you can grind the tip into a sharp cone shape to create  a heavy-duty awl for starting screws and finishing nails right on the mark and chipping dried glue from project corners.
• You can use binder clips to make multiple saw cuts all the same length. Clamp a jumbo binder clip to the fence and use a 1/4-inch-thick wood scrap pinched in the clip as a stop. When you are done with it, you can clamp the binder clip to the saw’s power cord so it’s always close by.
• If you need to sand small parts in a small area, consider using an emery board. (the ones you use to sand down your fingernails).  The wooden ones can be trimmed down to fit into tight places and they usually have one type of grit on one side and a finer grit on the other. Sanding Straws also do the trick.
• Use a straight edge to see if there are any dips or valleys in your wood. Lay
  the edge on the board and check to see if you have any daylight showing under it.
• To help not lose your metal straightedge, buy a pack of 1-1/2” round neodymium magnets and put them around the shop. For example, three on your scroll saw, four on your router table, four on your table saw and three on the underside of your workbench. This way when you’re finished using your straightedge, you just put it under your tool and snap it into place. Note, this only works with stainless steel straightedges, as aluminum straightedges are not magnetic. This trick also works with mechanical pencils.
• Always buy good quality tools. Good quality tools work better than cheap tools, so they help you complete the job easier and faster. They will also save you money in the long run since they last much longer than cheap tools.
