charliepetty Posted August 23, 2012 Share Posted August 23, 2012 I have noticed that currently different companies seem to have adopted RP25 as a standard profile with normally RP110 Tyre width, Bachmann seem to have this with a 0.030" depth of flange, is this normal as studying other manufacturers we seem to have: Bachmann Class 105 RP110 with a 0.030" Flange Depth Hornby HST RP110 with a 0.037" Flange Depth Hornby Ringfield RP113 with a 0.037" Flange Depth Heljan Class 17 RP110 with a 0.024" Flange Depth Heljan Kestrel RP110 with a 0.027" Flange Depth Heljan Railbus RP110 with a 0.027" Flange Depth Murphy Models 141 RP110 with a 0.030" Flange Depth Murphy Models 201 RP110 with a 0.037" Flange Depth Dapol JIA Wagon RP110 with a 0.024" Flange Depth Replica Railways 64'6" Chassis RP110 with a 0.027" Flange Depth Old Lima 117 RP127 with a 0.045" Flange Depth Romford RP110 with a 0.220" Depth WHAT SHOULD THE FLANGE DEPTH ACTUALLY BE? I accept that the older Hornby & Lima are 'Heavy' but the new stuff varies quire a lot too! Link to post Share on other sites More sharing options...
Pugsley Posted August 23, 2012 Share Posted August 23, 2012 WHAT SHOULD THE FLANGE DEPTH ACTUALLY BE? Looking at the figures above, I'd go for 0.030" +/- 0.006" - that should cover it Link to post Share on other sites More sharing options...

RMweb Gold martin_wynne Posted August 23, 2012 RMweb Gold Share Posted August 23, 2012 WHAT SHOULD THE FLANGE DEPTH ACTUALLY BE? Flange depth for RP25/110 wheel profile is 0.028" (0.7mm) max. See: http://www.nmra.org/... 2010.02.24.pdf Or 0.025" (0.65mm) nominal. See: http://www.nmra.org/...-25 2009.07.pdf Note that Romford/Markits are RP25/100, not RP25/110 Martin.

Jol Wilkinson Posted August 23, 2012 Share Posted August 23, 2012 This might help: http://www.doubleoga...rcialwheels.htm John That quotes 0.64mm or .025", somewhere in the low end of the range Charlie listed. Clearly DOGA have been able to have very little effect on the manufacturers, including Markits/Romford.. Link to post Share on other sites More sharing options...
