RMweb Gold big jim Posted January 13, 2023 RMweb Gold Share Posted January 13, 2023 The back to back gauges arrived today so I set about checking the wheels, all of them were 13.9 after putting in the gauge they are all 14.2 (hope that’s right!) you can see the brake hanger moulding is very close to the wheel flange before regauging, seem better now, a couple of tight(ish) wheels certainly turned better once done particularly on the axle with the larger hanger moulding 1 Link to post Share on other sites More sharing options...

(I'm not sure whose gauge could result in a 14.2mm value) Hornby rolling stock wheels are frequently set at 14.1mm The fact that your calipers are reading a value 0.2mm less in both cases suggests they are somehow reading low by that amount. No matter , you've added 0.3mm onto the B2B , which was definitely too low for comfort. I hope that should resolve it. 1 1 Link to post Share on other sites More sharing options...

Ravenser Posted January 13, 2023 Share Posted January 13, 2023 Just now, big jim said: They are cheap Amazon callipers, say no more! That might explain it. I just can't think of anyone who would sell a OO B2B that sets at 14.2mm : they all should be 14.4mm or 14.5mm . Hence me suspecting the measurements. I've seen something similar - in my case some years ago it was 7 x Hornby Mk3 coaches , and one vehicle taking exception to one handbuilt point (to BRMSB /OO Intermediate standard) on a continuous circuit layout. Push the offending coach through the offending point by hand and it was fine. Stick it in a train and it came off at that spot every time We hastily sourced a DOGA OO Intermediate B2B gauge . Every wheelset in the rake needed slight easing , and once that was done the problem went away. There are hints that Peco are quietly tightening the flangeway clearances in Streamline as they retool individual points (without mentioning it to anyone : Peco prefer not to discuss such matters) . That might explain the one point involved. Or it may just be that it's all right on the edge and one fractionally tighter wheelset (by a few hundredths of a mm!) on one slightly dodgy point pushes the wheel /track interface over the edge into derailment. Lets us know if easing the B2B has sorted it Link to post Share on other sites More sharing options...
RMweb Gold big jim Posted January 13, 2023 RMweb Gold Share Posted January 13, 2023 The back to back was also a loose used one off eBay just said ‘oo gauge’ in the sellers description, I don’t have the packaging to see the brand unfortunately Link to post Share on other sites More sharing options...
rovex Posted January 20, 2023 Share Posted January 20, 2023 The new Hornby Loriots have arrived at Footplate in Kidderminster. Hope they don't mind me sharing their photo Puzzled I couldn't find a separate thread for this new tooling. Be interested hear peoples views on this new model. 1 1 Link to post Share on other sites More sharing options...
