There are various support methods for the table. The Yarker Memorial Raceway utilized a standard 5 foot by 9 foot Ping-Pong table as its base. Valleyview Motorsport Park makes use of a simple custom build frame of 2" x 4"’s. My brother’s track, Cardiff Memorial Raceway was designed as a portable, three lane, high speed oval. It was build with four interlocking pieces (joined with wooden dowels) of track and utilized metal foldup legs that were purchased at a local building supply. The whole thing is transportable in the trunk of his car!
Build/acquire your table legs and support structure first. The best material for the tabletop seems to be ParticleBoard, as it is easy to work with and doesn’t splinter. Plywood would probably work well but is more expensive. Aspenite or Oriented Strand Board should not be used, it routes poorly.
You should fit the tabletop to the support structure and mark
out the whole track layout in pencil using the "Compass" that you built.
You may want to disassemble the tabletop and take it outside or to the
garage to do most of the actual routing.... or... you can fasten it in
place and do the routing right there. Routing creates a lot of dust
so give the first option some consideration. Secure the tabletop to the
table legs/support with screws and glue. Once attached, you want it firm
and immovable. Cover nail/screw holes with plastic wood and make sure
that none of the nails/screws are going to ever meet the router bit.
This could be DANGEROUS.
How To Fix Any Routing Mistake
Two words..."Plastic Wood". Spread it on with a putty knife
and sand it smooth with sandpaper. It may take two coats, but once the
paint is on, you’ll never know. A good trick when fixing a rough slot problem
is to insert a cardboard finger-nail file (or just wrap some sandpaper
around a popsicle stick.) This will keep the edges of the slot straight
and smooth. If you have a major alignment problem, open up the slot with
a knife/chisel, fill the whole slot with plastic wood and, while it is
still wet, use the popsicle stick or putty knife to re-open up the slot.
Dry sanding it when set will create the perfect groove. After routing,
you should always check the smoothness of the slot by manually pushing
one of your cars around the track. The guide blade should never grab or
jump. If it does, get out the Plastic Wood and sandpaper.
Painting
Use oil based gloss paint. First, paint each slot with different colors,
in order to make sure that each lane is differentiated and that the cars
get returned to the correct lane after a spin. Second, use two coats of
grey or black paint for the track surface. Finally, paint the off-track
sections green (grass) and brown (gravel traps). A light sanding with very
fine sandpaper will remove any pits or rough spots, particularly around
the slot where you will be laying the security tape. Make sure the track
surface is quite dry before adding the security tape or it may have trouble
sticking.
