Hi John, Nice Hogwarts Express. Looks great with the coupling rods/drive rods. I too have Ben's excellent wheels but am struggling to make these connections with six drivers and accomodate the necessary articulation to get round the sharp curves, (...)

(...) Hello Geoff, I have used flex rods as push rods , with the centre axel moving sideways. It works really well. But it needs a fare bit of weight above the drive wheels.to work fully (this was fixed when I put the train body ontop.) Sorry I have (...) (21 years ago, 16-Mar-04, to lugnet.trains, FTX)

(...) I'm not sure how well it shows up in the pictures, but the middle driver axle is a 'blind' driver - the flanges have been removed from those two wheels. This way, I'm really just running a two-axle configuration, the middle axle is more for (...) (21 years ago, 16-Mar-04, to lugnet.trains, FTX)

I gather these prototypes have some of the back of the wheel missing too, so the flanges of the outer wheels can tuck in behind. These means the (...) (21 years ago, 17-Mar-04, to lugnet.trains, FTX)

(...) I bought two sets of drive wheels from Ben. Four red ones for my American 4-4-0, which I just finished (less one black macaroni... grrr), and 6 black wheels for eventually making a 4-6-2. I haven't even started planning my 4-6-2, but I have (...) (21 years ago, 23-Mar-04, to lugnet.trains)
