i thought there had been a thread about guides suitable for drag racing 1/43rd cars on H0 track.
i did a reply that i had to measure the width of the guides, coming back from the basement, i can´t find the thread anymore?
well the answer to my question if i´m silly is of course "yes you are" and i know that only too well, but non the less, here are the guide width measurements ...
SCX compact 1.6mm
SlideGuide(R) 2mm
Artin 1/32nd guide 1.45mm
Scaley 1.8mm
Carrera Profi 1.85mm
Artin pin guide 2.1mm
Kyosho Dslot 1.5mm
H0 pin 1.0mm (Tomy SRT or Marchon?)
so, if the SCX compact guide works, the only guide still available and narrow enough is the DSlot guide. Or metall guide pin made from a nail or similar.
