I have just a posted a set of free plans for a simple but effective Router Spindle Mount for the Harbor Freight 1/4" Trim Router. I include all dimensions, material and part numbers to make this yourself. This spindle mount does work. You can see videos of this mount cutting various materials on you tube just search for Modular CNC. My free plans site also has other plans as well. Check it out at http://freecncplans.blogspot.com.
