My feeling is that I'd rather have the 3D models in my library, even if Hornby did make a Mk2a. I'll probably even do my own HST at some point! Subsequently I don't really follow the releases, but I imagine they might be waiting a long time for a 2a otherwise. 14 hours ago, bradfordbuffer said: And for the slightly larger minority scale of 3mm....but the boys and girls in British Ho and S should also take a interest! Yes, if I get it right, I hope it will have a wide appeal across TT, and other scales. There are possibly scratch builders in OO, who'd prefer to do there own thing too. I was surprised how many people are printing the 313 in OO. I thought that would have been catered for. I don't think I'm far off the TSO and the BSO bodies. I'm thinking about releasing them soon on an 'attribution license', so anyone can access, share, and modify them as long as they credit the original file.... and give an option for donations rather than charging anything for the files themselves. I just think of all the resources that I used to design them, that people have collated and share for free, and it seems like a better way to give something back. I also benefit from giving other people the opportunity to develop the files. That's my thinking anyway... this weekend I've been tasked with oiling two sets of garden furniture so not much progress happening ! 2 Link to post Share on other sites More sharing options...
Blefuscu Posted May 13 Author Share Posted May 13 This is the first draft of the BSO. I believe, externally, it's the same coachwork as the BFK, is this the case? The windows and doors are in place, but no steps or gaps under on the doors yet, and I need to shuffle the roof vents around... 4 2 Link to post Share on other sites More sharing options...

The windows and doors are in place, but no steps or gaps under on the doors yet, and I need to shuffle the roof vents around... Mk2s look Brill can't wait to get them wet! I'm just tinkering with the GUV in 3mm one notable thing with resin printing is the roof more often needs a swipe with some very fine grit paper to smooth layer lines (as most models viewed from above) but vents get in the way on the guv I've placed 'holes' at the slicing stage on each vent so when sanded the location is marked for replacement...'simples!' I know there might be a way via a drawing package but above my pay grade at the moment. I'm being cheeky how easy would it be for a second file for each coach to be included one with vents one with locating holes? Regards G 1 1 Link to post Share on other sites More sharing options...

The Mk2 and Mk2A builds used the same shell for the BSO and BFK. For completeness there were no Mk2B BSOs and the Mk2C, Mk2D, Mk2E and Mk2F BSOs all had second class window spacing so were a different body to the Mk2C and Mk2D BFKs. 1 Link to post Share on other sites More sharing options...

I think all printed roofs suffer from this, and it's not a bad idea. In theory, it's not difficult to do either. I simply cut the vents away from the model instead of joining them.... although they have to be scaled up first to create a small gap, and each cut needs a bit of cleaning up. I was thinking about it for the 313s, as there were 2 options for the vents there. Ultimately, I went in favour of trying to sand around the vents, instead of more tiny things to print/scrape off the FEP. The other issue is version control... if I have to make a change to the body later, that needs rippling out to every version I made. I think all printed roofs suffer from this though, and it's not a bad idea... but i might just see how the vented version turns out before I try the vent hole version. 1 Link to post Share on other sites More sharing options...

The Barrowmore group have the BR coach diagrams on their website. They aren't the most detailed drawings, but they are dimensioned and you can see stuff like the different window spacings. http://www.barrowmoremrg.co.uk/BRBDocuments/CS/Book_No_200_EK_web.pdf I guess it was thought worth having the expense of different body shells to get an extra three feet of van space in the later Mk2 BSOs.

Flood Posted May 14 Share Posted May 14 Just one thing to be careful of. The BR diagram has the BSO roof vent positions for the Mk2 BFK and Mk2A BFK, I first noticed this when Bachmann got theirs wrong and I noticed the BR diagrams in Harris were also incorrect. The positions shown on the Mk2B BFK drawing are correct. Link to post Share on other sites More sharing options...

Yes, I've got those thanks - they are a good starting point. I use them for scale, and the layout of main features.. and I keep a printed copy next to me to make notes on. 1 Link to post Share on other sites More sharing options...

The reproduction of AB104 in my pdf of book 200 from the Barrowmore Group is pretty poor. However, the older diagram BR164 is much clearer.

Blefuscu Posted May 16 Author Share Posted May 16 As an aside, I've just had an email back from the British Library regarding that book. TLTR: Technically, they are still in a bit of a mess. Last time I was there to look at some OS maps, I had to put a paper request in and come back in an hour - but this is in another building and will take two days. Quote Dear Michael, Thank you for your enquiry. The book - British Rail Mark 2 coaches : the design that launched Intercity, shelf-mark: fm01/1432 is available to request for the registered readers only. This book is stored in our off-site location at Boston Spa, Yorkshire and the delivery time is 48 hours. You need to make two visits, one for to place the request and another to view the material. We do have another copy but that is not available due to the cyber attack last year. If you have a reader pass then please make a note of the shelf-mark, collect a paper order form from the Reading Room staff, fill in the required details, and return it to the Issue Desk. We currently have a limit of 6 requests per day. Please note that last orders should be submitted by 15:45. We are not taking any advance orders at the moment.

What % should the slicing be scaled at to bring it to 3mm 1.101 scale normally just wing it then measure but not the most scientific way..
