7mm David Andrews E1 4-4-0

[Lancastrian]

Following the recently completed D1, I've made a start on the E1. As with the D1, the bogie has been put together first.

The support brackets for the compensating beams, drilled and 0.6mm rivets fitted.



The basic bogie frame assembled.


First problem, the etched holes do not line up.

Once some judicious filing had taken place, I could continue assembling the bogie.


Finally, mounted on its wheels.


When it has had a thorough clean up it will be ready for priming.

Thursday afternoon saw the frames erected and a check of the driving wheels with the compensation beams. 12BA bolts soldered in place for the brake hangers.

Scale Hardware rivets fitted.


Two pieces of NS soldered together and filed to shape for the running board/platform supports.



Etched part for the support bracket drilled and fitted with rivets and then soldered to one of the supports.


First one now seen in place on the left hand frame.

Replacement vacuum brake cylinder turned up, with a spigot for the tender drawbar.



The guard irons foul the leading bogie wheels, so some modification is required.
Original on the left and re-profiled version on the right.


Clearance check.

As the loco currently stands. Brake gear and sand pipe brackets to complete.

The front is raised from the spring in the MOK bogie pivot.

The brake gear is complete and the sandpipes have been finished off. The brackets are made from phosphor-bronze strip with a cosmetic rivet.

Work commenced on the buffer beam, firstly with the addition of 0.7mm rivets, before being soldered to the platform.



It was then the turn of the drag beam.

Ian Can I ask, where did you purchase your Scale Hardware rivets from? Was it a UK supplier or from the US? Your E1 is coming along nicely, an inspiration.

Another fab build and great views to help with scratch building in 4mm, thanks for sharing them.

Hi Tony,

Thank you.
I purchased the rivets directly from Model Motorcars in the USA.

Hi Duncan,

Thank you. Hopefully the instructions are coming in handy as well.

Cab front.


Modifications to the cab side sheet returns. This is mentioned in the instructions until stage 31. We're at stage 7 in the build here.


Checking the fit against the cab floor support.


Cab now in place.


Moving on to the firebox, the D1 kit had an additional etch to go behind the firebox front, so that there was extra material to allow for filing the wrapper into a nice curve. The E1 kit does not have this, so I annealed a length of 2mm sq brass bar and formed it to shape.


In the meantime, handrail knobs, washout plugs and rivets were added to the wrapper.


The main body of the firebox was completed, with the 2mm sq bar soldered in place. It will next have the firebox front filed to a nice (hopefully) curve.


Before that though, a test fit.

Thanks Ian, They certainly are. I need to finish other things off before properly getting into building , but the instructions, plus the photos is helping with working out how to do it in 4mm. I appreciate someone is about to bring out a kit, but looking at it there is so much that would have to be changed and I have already cut a fair bit of the tender out.

Modifications made to the frames to prevent the leading bogie wheels rubbing and not rotating on tight curves, following a similar alteration to the D1 4-4-0.

Scrap brass etch marked and filed to match the frame outline.


Frames after the halt etch "cut-outs" have been removed.


The brass inserts were then soldered in place on the inside of the frames.


A shot with the bogie in place.


The bogie pivot is a replacement item purchased from MOK.

Might be anathema but perhaps black plasticard in place of the brass frame inserts?

No shorts, and the paint don’t wear off…

lovely build!

Hi Simon,

The D1 which was modified first has been tested on the layout where I noticed the issue, and now is fine. The E1 should be just as good. The additional 0.7mm throw allows the wheels to stay clear. There have been no shorts so far.....fingers crossed.

I did the plasticard trick on my King on a “just in case” basis.

Wonderful work Ian!
A real inspiration.
I look forward to further posts.

Next stage is the smokebox. Now this should be fun !

Three layers.


Not forgetting the half etch wrapper.


Oh, and the boiler tube itself....


Additionally, only the outer wrapper has any holes etched for the handrail knobs and steam pipe.

Jubilee clip, low melt and the oven?

Jubilee clip, low melt and the oven?

Hmmm, unfortunately it can't go in the oven as there is a plastic 35mm film tub filled with lead in the boiler.

However.....

Two rings made from some 2mm x 1mm brass suffices to replace two of the inner layers.

Smokebox "crinolines" in place.
