Step 1: Compound Miter Saw
Because I didn't open the clamps all the way, the second time I had to put the saw back on, I had a little trouble lining up the holes. To prevent this, I traced the outline of the saw feet on the table top in permanent marker.
Step 2: Router Table
The table top is made of some pretty soft MDF, so I had to be careful with the little notches. I cut out the basic shape by hand with a jigsaw and coping saw. I shaved them down with a chisel until I had jut the right size that the router would sit flush with the tabletop. These little teeth hold the saw in place from below, and also give me something to rest the router one while I tighten the clamps.
I bought some countersunk bolts that fit the 3 mounting holes on the face of the router. I took a piece of 1/4" plywood I had laying around and drilled and countersunk some holes to match the ones on the router. I took some 1x3" scraps and filled in the void in the table top and screwed them to the underside of the plywood with very small countersunk screws.
I drilled a hole in the tabletop for the router bit and then I drew a center line to help align the fence.
I took a scrap piece of an old door jamb and cut it to the length of the tabletop. I put some wood putty in the holes and sanded it smooth. I screwed a piece of 2x2" to the back to give me something to stand it up and clamp it to the tabletop. At first I used some big C clamps, but now I use some quick grip clamps to hold the fence to top.
I like to use magnets to hold the chuck/collar/arbor tools close-by. I don't like having to look far for the tool to change a bit or a blade, so I added an old hard drive magnet to the underside of the top. I traced the tool's shape on the top above where it lives, so I won't forget it's there.
Step 3: Finish
The router doesn't get used very much anymore, but I have had to use it a few times when I need a smooth cut with a router bit that doesn't have a bearing. I'm a lot more comfortable moving the wood through a machine like this, than wielding a heavy tool and hoping for precise results.
