I built this mobile base because I was not happy with any of the store bought ones I had tried. I also had bought this Frued 2 1/4 hp router combo kit from woodcraft when they were on sell during christmas. If you did not buy one you missed out. This thing came with an aluminum base plate for table mounting. It has height adjustment and bit change above the table. It also came with a plunge base. All that for $150 dollars, I could kick myself for not buying two. All these up grades had been in the design stage for years. My shop constist of my 16’ x 22’ carport. And all my tools have to fit into the 6’ x 16’ storage room on the end of it. So having all these upgrades in a small package was a must. The base made of yellow pine and all joints are mortisted and tennon with 3” srews for added strength. I also added 1/4” steel corner brackets to help support the weight. The base has 6 swivel casters, 4 of wich are double locking on the ends. There is a set on the right side under the plywood for extra support. The router table extention wing is constructed from two pieces of 3/4” melamine laminated together and hard maple along the edges. The outfeed table was constructed useing a tortion box method. It is flat, sturdy and rather light weight for it’s size. I attached it to the cabinet of the saw with KV folding bracket. The last two pictures are during a work setion before the up grades. I stll have to construct the router talbe fence and a box under it for dust collection. That is when I get a dust collector. Hope all you jocks enjoy.
