That must've taken a fair bit of elbow grease to get the flange off, I wouldn't be looking forward to doing the other! Mind you if you keep the loco facing the same way you may be able to leave it on!

This a rather interesting concept, and one which also gets my brain thinking in terms of my 009 layout, they had tight curves on narrow gauge lines too!

Keep it up

JaymzHatstand: Surprisingly, this was fairly easy. I was being very cautious so as not to damage the nylon drive gear, but estimate about 10 minutes of (gentle!) filing achieved roughly this, with maybe 5 minutes of polishing up afterwards. I know about sharp curves - these curves are 140mm radius! I would not enjoy trying to get the 0-6-0 to go around the smallest radius that Tomix make - 103mm! I'm also looking into getting hold of some foreign-made N-scale 0-4-0s to try to convert them into passable UK might-have-beens... Particularly the Fleischmann 0-4-0 and the Tomix Percy (see https://www.newhallstudios.com/~station/images-lib/tomix_n_scale/TO-93808/TO-93808_02_lg.jpg ) which should only require the face removing and replacing with plasticard and a suitable smokebox door, followed by a repaint. As a bonus, it comes with three faces, perfect should I decide to have a "Day out with Thomas" event on my layout!

EDIT: Have just removed the other wheel's flange in about 10 minutes, and it runs pretty sweetly around the curves. I'll run it in tonight, then look for any tight spots...
