GWR Headlamp drawing.

Does anyone have a drawing for 5" GWR headlamps as I would like to make a set.

Thanks.

Have you tried GWS at Didcot?

If you mean a loco lamp I have a full size drawing.

I’ve been attempting a GWR lamp but didn’t have much by way of information apart from only photo’s and some general dimensions I’d found on a thread for the smaller scales. I saw here that Dave ‘Kipford’ had a copy of the GWR drawing, which he kindly let me have. It wasn’t that clear only being a copy on A4 but far better than anything I had. What t did have was t GWR drawing number so I went on a search for a better copy.

I didn’t have to go far, only over to Roger’s Speedy thread. Back in April he mentioned he had the drawing. Not only did he have the drawing, he’d done the majority of the parts in CAD and he kindly gave me a copy of the assembly in a .stp file. Understandably it was in 5” scale and also understandably it is to the level of detail we expect from Roger.

With no effort at all I chucked it at my 3D printer, back row left.





Back Row left to right

- Scaled up to 150% for 7.25” gauge.

- Attachment of the handle and front door. Handle too weak and broke off.

- Try it in black PETG rather than PLA. Very stringy result.

- Thickening of various thin components that the slicer ignored.

- More thickening and an attempt to apply the GWR embossed chimney.

Front Row

- Latest effort, domed roof expanded slightly to so it makes contact with the handle to make it stronger. Further attempt at GWR logo

It does show promise although being PLA may not be suitable for attachment to the smokebox as it could tun out to be a bit messy. Elsewhere should be OK. The only other thing would be that a bit of work would be required to get it to print in 5”scale as some of the parts would be too thin.

Next thing is a lens and some electrics. Roger has it sorted to fit his 5” version so getting it into mine shouldn’t be a problem.

Thanks Roger
