Alternative track materials

Well my track it's made out of slot tracks, just because I'm on quarantine and I can't get choroplast right now. I've thoug of using electrical trunking like referred above but it lacks the turns. Aluminium trunking could also do the trick but I think it will damage much more the cars than plastic. The orange track it's cool but doesn't allow contact between the cars, and if not correctly mounted one track will always be shorter or longer than the other imo.

Still think that choroplast it's the best solution for those that can't buy or get Sizzlers fat tracks etc in Their own countries like myself.

So cardboard isn't a discovery but I recently re-floored my basement and the boxes the planks came it seem nearly perfect to use as a wide banger track. It even has walls already there and ready! So if you know anyone that is redoing floors, maybe ask them to save a few of the boxes...might save you some cutting and folding, if nothing else.

Silly question, but how many people have tried using vinyl rain gutters for their builds? Split it all the way down either side, looks like you could run two cars wide in there ........ or split it the other way and have single-track drag lanes, ready for orange track to be laid down.

I was going through the garage   Looking for Alternative track material. And I came across this baseboard The backside has a perfect cut out for a hot wheel track or just the Hot Wheels itself. Now if I can figure out what I'm gonna build and where I'm gonna build it.youtu.be/F2hdzZa4c8Q

Well I used  48' of the baseboard I had found  in  my garage. It's just hot glued to the wall for all my straight runs .The baseboard is also  wide enough to park some extra cars along the sides on the flats. 

I am currently trying 2 different materials.  Pink foam and used flooring (interlocking planks).
I found that the flooring, since made to float when installed the back has an ~1/8" thick plastic coating on it.  It seems to be perfect for this use, as it is slick, flat, and tough.  It does flex some, though.  A single plank I am using is 5' x 6" wide.  The ends are made to lock together so longer runs could be made by gluing a spine to the underside for reinforcing.

the pink foam is cut with a hobby band saw, and hand will be shaped for contour.  Foam sands/shapes easy, and a coating of paint + thinned (acrylic) joint compound + paint should give a tough surface.

another hot wheels track material that I used years ago was 2 rolls of flexible, vinyl baseboard, glued to a wood backing.  the curls that go towards the floor are the walls, and the wide flat sides but up to each other.  a 4" baseboard yiends an 8" wide track

 i stumbled across this stuff, and some ideas come to mind, the cover reminds me a lot of an orange hot wheels

20 years ago I built this. 
dragged out of the weeds this weekend as good track building mojo

tilt launch
(does anyone use a tilt launch now?)

extruded aluminum.  the bad part that made it a poor race track
the shape was like this

so one lane would drag the top of the car
we  would still load it with 8-10 cars and launch
lower flat track was basicly a steel 2 x 4 with no holes in it
we called it houston traffic, because the chaos at the open section was great to watch,
and reminded you of the insanity of the freeway

has anyone tried to make curves out of a bowl?

like this:

15" diameter, super slick, and the acrylic could be painted, and glued,
maybe you could backlite from under

cut in half for a 180°

You could rebuild the track so it looked like this:


....... and then your two outside lanes would be the actual racing surface, with the inner lanes being bolted together

Was doing cleanup at the house and forgot I had this thing, (pic is example)
(looking at things with a different eye)
the top is aluminum, 3" and 2 halves riveted together
compound curves but not too drastic
may have to do some tests
