Because this track will be portable, I build the base using 3/8" plywood and 1"x6" boards for three sides and 1"x4"
for the front
All the routing is finished, and what used to be a sheet of Lexan is now a pile of spaghetti. I made a 3" high
eggcrate grid from the sheet of cardboard, so I could jigsaw out the actual roadway. The cargboard grid keeps
the jigsaw blade from bottoming out and doesn't slow down the cutting. Good thing nobody was around to watch
me wrestle all this stuff into the box.
This is what's left of the sheet. When I first laid it on the cardboard drawing, I traced all the lines onto the Lexan
with a felt pan.
I used 1/8" Lexan for the roadway because I wanted steep elevation changes. Because the slot needs to be
1/4" deep, I glued 1/8" Plexiglas spacers to the underside, then a 1/8" strip under the blocks to tie everything
back together
This is where I started raising the roadway. Screw holes are drilled and countersunk and the wood blocks are
glued to the base. Because the plastic is so flexible, you need to keep checking the elevations to make sure
cars don't bottom out.
Hey, maybe I should build a whole track out of clear Plex...Ice racing...yeah, that's it
