The Finished Product

Here's an overhead of Cory's finished table.  The "ripples" you see towards the top are due to the way the light was hitting the table in the garage where we were assembling.

You may find that your cup holders will need a little bit of extra sanding in either the baseboard or racetrack to get a perfect fit.  Some went in without any problem, while others were more stubborn.  Just do this by hand, as it probably won't take too much.

Also, we had portions of our rail that were more difficult to fit onto our table.  We just ran an electric sander along the outer edge of our race track, and tried again.

It takes quite a bit of trial and error, but if you've cut properly and used the same wood pieces, it'll go.  Just keep playing until it latches.

We didn't attach the rail to the table, but did screw the race track and the center insert to the baseboard from the bottom.

We used 1.25 inch screws.  When we put the insert playing surface onto the table it came up just a hair on each end.  After putting in a screw at each end, the insert was completely flush with the rest of the table.
