Went to lowes looking for these low voltage shields, cool, on sale $0.64 each... with a wizzer [air / electric cut off disc] trim to make 2 connectors on one end...
Stocker and the trimmed version ;
Slide the track strips onto the connectors ;
Drag Track to Hot Wheels adaptor, rotate the shield 90*, plot out your DT and HW measurements, cut slightly large and file to fit ;
Slide the track sections onto the connectors ;
Race ready ; add some 90*s, couple 180*s, 2 more 90*s and with another HW to DT adaptor you're back onto DT for the finish...may need a couple milk carton plastic shims as the HW track is thinner ;
Adds the option to add loop de loops or jumps...
