stock_2007 Posted November 29, 2018 Share Posted November 29, 2018 Hi I'm trying to work out how to cut the vents in the side of a DVT for Chiltern Railways the vents were put in I believe to help with the cooling of the APU.As always any help is very welcome .

RMweb Gold Corbs Posted November 30, 2018 RMweb Gold Share Posted November 30, 2018 If you use masking tape to mark the vertical and horizontal limits of the vents, (I would then mark the vents using pencil too) then use a very small drill in a pin vice, you can drill several holes in the bodyside in a line, then use a sharp blade to join them together.

'CHARD Posted November 30, 2018 Share Posted November 30, 2018 (edited) My personal preference - to carefully cut out the small (roughly square) apertures where the vents will be, then insert an interference-fit square of pre-scribed plasticard in each. Note - referring to photos of different DVTs, I'm not sure if the model already comes with the two square vents nearer the cab. For the vented door aperture, I would fill the window with a square of plastic the same thickness as the body, file smooth, then drill and slot the six horizontal louvres with a file, then put a backing piece of plasticard on the inside of the shell.

RMweb Gold chuffinghell Posted November 30, 2018 RMweb Gold Share Posted November 30, 2018 (edited) An alternative would be to cut out the door and have the replacement panel 3D printed complete with the vents then glue it in place Edited November 30, 2018 by chuffinghell 2 Link to post Share on other sites More sharing options...

I had wondered about trying some kind of decal for the vents? Edited November 30, 2018 by stock_2007 Link to post Share on other sites More sharing options...

RMweb Gold TravisM Posted November 30, 2018 RMweb Gold Share Posted November 30, 2018 I’m thinking of doing a Chiltern Trains DVT and interested in how people have done both the vents and exhaust on the roof. Getting a 3D printed replacement door with the vents moulded in could be the way to go but if your going to do that, do the exhaust vent as well.

RMweb Premium newbryford Posted November 30, 2018 RMweb Premium Share Posted November 30, 2018 (edited) Now that is a really good idea no idea how I'd get the replacement panel made but well worth thinking about. I had wondered about trying some kind of decal for the vents? I used decals on my yellow NR DVT, but these vents are a bit large for that method. I would cut holes as detailed above and then use plasticard fillets to fill in the angled sections. I like the idea of 3D printing, but matching the curve/tumblehome could be fun. My personal preference - to carefully cut out the small (roughly square) apertures where the vents will be, then insert an interference-fit square of pre-scribed plasticard in each. Note - referring to photos of different DVTs, I'm not sure if the model already comes with the two square vents nearer the cab. The vents were certainly on my base model DVTs (that are now yellow obviously!) in my avatar.

Just make sure you select the correct bodyshell, assuming Peters spares have the Hornby Mk3b DVT body available. IIRC it was quite a pricey item when it came out.

Has anyone any ideas on how I can take the wording off the DVT sides? T-cut and a cotton bud usually removes all printed on wording, just rub softly and stop once youve removed the branding you dont want, whilst checking occasionally to see how much is removed NL Link to post Share on other sites More sharing options...
