Show off your tracks
i made some connectors... they are the thickness of the purple stockers [plus bumps]... the sloppies don't have bumps...
so when you push the sloppies connector 2 inches into the uphill track section it tends to pull the siderails [IN]....i made them 4" long... i had to cut them to 3" because they pull the track in so much...
push 2" of the connector into the uphill, it narrows it more than the 1" into the lower track... no seam hang-ups... i didn't plan this.... SERENDIPITY !... i made 240, pm me with needs.
they are white, light dispersers from 4 foot long ; LIGHTS OF AMERICA STAINLESS STEEL SHOP LIGHT. mine were 49" x 7" x 1/16", friend and i cut them into 1" strips on a table saw, then cut them to 4" long, shoulda cut 'em to 3" long, on a chop saw..they are slightly brittle...
Next time you send some cars back out this way Smitty maybe you can throw a few in there. No hurry at all it usually just a couple spots that develop problems. Tastelikedirt raceway is in a 40 foot metal storage container and right now it's got about a foot and a half of snow all around it with more falling as we speak...ah sunny California.

Hey what a great idea,...I bought some HW track sections and the connectors were soooo tight that it caused the track to pull in like you said. I'll try and cut down the connectors and see if this helps.

the "MAGIVER"... if it looks like it was made from spare [junk] parts, it was ! ; 
press the washers towards each other ; 
boom ... ; 
camera car will run in the left lane !
home made, starter and track support...bottom section of a H.W. [3] lane, [4] section "bump track"... popped off the [3] lane finishline [will modd later]...heated with a candle and bent the track connectors and dividers down slightly... i use yellow with red & blue striped, H.W. or matchbox track?... it is flexible enough to reverse arc... to 1/2 section of DRAG TRACKS...to D.T. transfer...to [9 or 10 ] 20" D.T. track sections as runout... to [1] 24" section of H.W. yellow [no-stripe]... to the finishline [1/2 is a H.W. dual lap counter 1/2 is a H.W. indy 500 roll-up finishline]...to [1] 24" H.W. yellow to the towel ... whole track pix when i set up to race next.
MAGIVER, 3 LANES, PVC STAND, LEFT LANE = VIDEO LANE [ARROW] ; 
TOP AND BASE SEPARATE FROM THE LEGS FOR SUITCASE STORAGE OR TRANSPORT...
the 3 lane track section is made from the bottom section of [4] on a 3 lane downhill race track...notice the lane dividers flare out at the last inch of track.... allowing room for the doubled up siderails of the orange / yellow track...and has the track connector tabs...
. THE TRACK HAS SMALL FLARES AT THE CONNECTOR TO ORANGE / YELLOW ... THROWS THE CARS OFF THE TRACK...
BACK TO THE DRAWING BOARD !
Yes, I've noticed this as well. When it's really cold, the seams become more stiff and can cause cars to come off the track when they usually don't when it's warmer.
