tony_harker Posted June 21, 2020 Share Posted June 21, 2020 Many of Hornby larger locomotives are fitted with flangeless wheels in their trailing trucks under the cabs. Does any one know what radius the locos would traverse if these wheels were replaced with flanged ones? TIA Tony Link to comment Share on other sites More sharing options...
atom3624 Posted June 21, 2020 Share Posted June 21, 2020 I genuinely don't think they would!!I suppose the equivalent of 10th radius would be about right. There is a 'bit of movement' of the axles' in the brass bushings / bearing, which may permit a slightly smaller radius than you'd think, but generally it's as they say - presenttion only. If you've a nice 'scale' layout still using 16.5mm gauge, then it may be worth trying, but definitely a LOT more than 4th radius I would guess - hence '10th' above!! Al.

2e0dtoeric Posted June 21, 2020 Share Posted June 21, 2020 As the cartazzi truck doesn't move, on modern-build steam outline loco's, don't bother fitting the 'display' flanged wheels. They MIGHT be ok on a nearly straight end-to-end, providing you have used 'express' points, not the tight curve ones! Link to comment Share on other sites More sharing options...
Chrissaf Posted June 21, 2020 Share Posted June 21, 2020 My flangeless wheels (A4 Pacific) stick out (overhang) my curves by about 8 to 10mm and that is on Radius 4 curves. As my truck is not hinged and part of the chassis, I can't see the flanged display case wheels working on anything other than a dead straight track.

tony_harker Posted June 21, 2020 Author Share Posted June 21, 2020 My minimum radius is 4' and there is a little sideways play so I might get away with it. Especially if I use scale width wheels. Link to comment Share on other sites More sharing options...
