Accomplished what we set out to do today.

3 sheets of 1/2" MDF as an underlayment. It's staggered so the seams are offset from the old OSB below. Only needed 3 as the ends of the track is banked enough to raise above it.

Precision banking system. :) Remember, not really going for a lot here. Just enough lift to give a slight incline.

Sophisticated fencing system :) Just finding a straight one at the local yard was the fun part.

All routed. Even put in the pit lane Doc told me to :)
Cannot say enough good things about the router WITH the vacuum port. I have sheet covered the entire basement and no need. This really worked well and venting out the dust.
Ok, tomorrow is spackle/sanding. Maybe get the gains routed if I have time. Grandkids command a supper with us and they out rank even a slot car track.
BIG thanks to The General for helping me today. She really did a fine job.
Oh, good seeing Dixon John drive by today...at least he waved :)
