Blank Universal Large 10.5x10.5" Square Router Base Plate - Two Handle

Looking for a BIG router base to mount your router to? Our blank universal 10.5x10.5" square router base with double handles might be the ideal upgrade. It is compatible with any trim/compact/palm router as well as full sized routers.

The router base features a 1 3/8" diameter stepped-hole that is 100% compatible with "porter cable style" (P-C) router bushings to give you the greatest capability. The removable black phenolic plastic handles provide an easy, ergonomic grip to give you secure and precise control of your router.

This 10.5x10.5" router base gives you superior stability and accuracy thanks to its huge footprint. This comes in handy when using your router with tray templates or pocketing projects where the router needs to stay level and maintain contact with your template while you are pocketing out open areas. 

The square design allows you to maintain an even distance between the center of the router bit and the outside perimeter of the router base if you want to use it in conjunction with a fence or temporary block to create straight channels, flutes, mortises or other specialized cuts.

Finally, the 3/8" thick, clear base plate provides unparalleled visibility so you can see your workpiece, stencil or template while you are moving your router around. 

Fits Any Compact Palm / Trim Router - A Universal "Drill It Yourself" Solution

Unlike the majority of the aftermarket router bases we manufacture, this specialty base is designed to be a "drill it yourself" or "mount it yourself" solution. The blank universal base features two precut recessed channels that will allow you to mount it to any router that has the mounting holes inline (not offset) with the center of the router shaft. You then mark and drill the remaining two mounting holes in the base by hand, then countersink them with a countersink bit before mounting it to your router.

As most routers have four mounting holes it is recommended that all four holes be used to mount the base to your router. Two through the pre-cut channels already in the blank universal base and the other two that you mark and drill yourself. It is important to note that if your router has mounting holes that are not inline with the routers shaft (where the bit goes) and are instead offset, you wont be able to utilize the pre cut channels and will have to drill and countersink all mounting holes. This offset is more common with compact trim/palm routers rather than full sized routers. See the photo on this page for a visual representation of what this looks like.

How To Mount The Blank Universal Base To Your Router

• Remove the OEM base and line it up center with the blank universal base. The base features an etched "crosshair" to visually represent the exact center of the hole in the base.
• Rotate the OEM base until two opposing holes fall inline of the pre-cut channels in the blank universal base. Please ensure your routers mounting holes are inline with the center of the router shaft/collet if you plan to use the pre-cut channels for two of the mounting points.
• Assuming your OEM base is still centered with the blank universal base, mark the other two holes through your OEM base onto the blank universal base. Note that applying some painters tape or masking tape to the blank universal base might help, as acrylic is hard to mark with anything but a permanent marker.
• If you are having issues centering your OEM base on the blank universal base, you could use the alternate method of installing a router bushing with a 1/4" hole into the blank universal base, then installing a 1/4" straight bit into your router and through the bushing to act as a centering pin. Then lining up your router (with the OEM base removed) and marking the holes to be drilled.
• Put your OEM base (or router) to the side and place the blank universal base on a piece of scrap wood or workbench that you can drill through. 
• Using a small diameter drill bit (1/8" diameter or less) drill through the marked holes in the acrylic base. Then progressively move up to a higher diameter bit that is large enough for your router mounting screws. The idea is to start with a small diameter bit as a pilot hole, then move up from there, to avoid cracking the acrylic while drilling.
• Using a 1/4" to 3/8" in diameter countersink bit carefully countersink the holes to enable your router mounting screws to sit below the surface of the blank universal base. It's always best to start with shallow holes, test the mounting screws to see how they sit in the hole, than to countersink too deep in the first go.
• Attach the blank universal base with all mounting screw points drilled out and countersunk to your router. If your OEM router screws are not long enough, a trip to the local hardware store may be in order to purchase longer screws. Just bring your OEM screws along to ensure you match the thread diameter.
