Staffordshire Posted August 25, 2020 Share Posted August 25, 2020 LNER/BR B17 Class - Wheels info I am trying to discover the wheels dimensions etc for the LNER/BR B17 Class .... Need to know size, number of spokes etc etc for both Loco and Tender ? I think the Driving wheel size is 6' 8", with 20 spokes - Is this correct ? Leading wheel size is 3' 2" ?? How many spokes ? Tender wheel size is ............ ?? Lastly, which Manufacturer makes the equivalent 4mm scale wheels ? Many thanks, Ian Link to post Share on other sites More sharing options...
Caley739 Posted August 25, 2020 Share Posted August 25, 2020 "Wheel Specifications for the Modeller" by Mike Sharman 1982 gives the following for B17: Driving Wheels 6' 8" with 20 spokes. Leading Wheels 3' 1" with 12 spokes. Tender Wheels 3' 9" with 10 spokes. Link to post Share on other sites More sharing options...
RMweb Premium Michael Edge Posted August 25, 2020 RMweb Premium Share Posted August 25, 2020 The Sharman reference is right for the loco but tender wheels vary, I'm not sure about the GE style ones for the Sandringhams but most of the GS tenders for the Footballers had disc wheels. I think one B17 may have had a bogie with 10 spoke wheels but I don't know which one. Link to post Share on other sites More sharing options...
Wickham Green too Posted August 25, 2020 Share Posted August 25, 2020 Yes ..... with the crank pin between the driving wheel spokes. Alan Gibson offers a suitable driving wheel - but not an EXACT match for bogie or tender so you may have to compromise a little ( Don't forget Gibson's wheels can turn out to be a little smaller than advertised ! ).

RMweb Premium Michael Edge Posted August 25, 2020 RMweb Premium Share Posted August 25, 2020 Smaller is OK, all wheel tyres get turned down during their lives - up to about 2" off the diameter. Link to post Share on other sites More sharing options...

As far as I know only 61639 was so fitted, but it was a B2 by then. D Link to post Share on other sites More sharing options...

Thanks again. Ian Actually looking at a couple of photos on the web ... I am not sure about disc wheels for the tender ??

As far as I'm aware, all these had spoked wheels. This is certainly the case in the photo of 61658 on p22 of Yeadon's Register Vol 5. Link to post Share on other sites More sharing options...

Yes and no .......... I've had ( pony truck ) wheels for a Southern loco nominally 1'' undersized because the correct size / spoke combination's not available - but which measure about 2'' under that - yet still have conspicuously full depth tyres. Fortunately the nominally 1'' oversize wheel's available with the correct spokes - and measures out exactly right. Link to post Share on other sites More sharing options...

This is certainly the case in the photo of 61658 on p22 of Yeadon's Register Vol 5. Just remember that as far as the railway was concerned, the factors that mattered were the diameter and bearing journal size and centres (which in turn relate to the load capacity of the wheelset). Whether the centre was spoked or sold was technically irrelevant and even tenders with mixed sets are not at all unknown. Jim 1 Link to post Share on other sites More sharing options...
harry lamb Posted August 29, 2020 Share Posted August 29, 2020 (edited) Good evening Staffordshire, the nearest match in 4mm would be the 'Ultrascale' 12 spoke 3' 2" job. An inch too high I know but as the B17 was a Darlington built locomotive just like the D49 and it shared the same casting as the D49 bogie wheel centre. Both being built around the same period. Later Darlington built LNE classes resorted to the standard Doncaster 10 spoke 3' 2" bogie wheels. Driving wheels for the B17 are 18 spoke Doncaster standard. Ultrascale produce both these wheels but you need to plan ahead. The waiting time is 'Mummyfing' but worth it in the long run. And it is a long run! Regards. HL.
