Green Park Train Shed Update5   Leave a comment

DEVELOPMENTS AT BATH GREEN PARK
As construction of the train shed has progressed I have looked again at various aspects of the train shed design.
The TWO issues are: Combe Down tunnel track that cuts across the middle of the train shed AND access to uncouple locos at the platform ends.
The former – nothing to do there it is what it is
The later has developed further. Originally I thought of a lifting flap in the train shed roof but early on discarded this as the structure just will not be strong enough to take constant handling in such a way never mind the odd heavy hand!
So worked on leaving a gap in the roof for that ‘Hand of God’. After all, this whole area beyond the dividing track was going to be ‘off stage’ and so is a big bonus.
Now that construction has moved forward far enough I can see that I may not need to leave as large a gap as I had first thought.
I plan to add one more bow string as you can see in the photo below.
This has an added advantage that the 3 ‘X’ trusses on the far side of the roof can now run right across from front to rear sections and so amalgamate the whole visually.

The view internally of the extra bow string girder
Today I’ve started glueing the ‘X’ trusses in place on to the main bow string girders.

Both roofs are now painted on their undersides – sooty cream. For me its important that the model looks ‘Shabby Chic’. I’m trying to represent Bath Green Park in the 1950’s and 60’s when it was looking rather past its best.
The glazed roof on the left is, on the original, a solid pitched roof but I’ve made it glazed to allow more light through and allows a better view into the platforms as the main roofs do cover a large area of the platforms.

Green Park Train Shed Update4   Leave a comment

I must be spending 4 or 5 hours a day on BGP train shed, well, I haven’t got anything else to do!

Big progress in the last week: I hope to finish the rear part of the train shed over the next 7 days and then be able to move onto the front and more visible part of  the train shed.

The pitched glazed roof on the side of platform 2 is almost complete – I ran out of 1.2mm ‘T’ bar strip to complete the glazing bars. You can see I’m only 3 sections short. Ordered and will finish that in the next couple of days. Issue – there is a lot of light reflection from the room window on this glazing and so I have experimented with a matt lacquer spray on a test piece of acrylic. Will reduce the light reflection but also the view down onto the platform. Going to wait on that decision until I have to fix the glazing in place.

You can see just how many truss beams I have cut, fettled and glued in place. 100’s already and more to finish this rear part of the train shed. One of the most difficult things is trying to line them all up. I only have a side view and even with my GoPro camera and the good old mirror trick it is still very difficult to align them all perfectly.

I’m pretty much ready to cut out the roof for both sides now. The black card will be used as formers to cut the 1mm birch ply

I’m doing a trial run with the ‘X’ trussing on top of the main bow string girders so only attached with Bluetac at the moment.

The  ground frame is ready for platform 2 crossover. This was worked by the loco fireman and used by trains terminating at Green Park to enable the loco to run round the stock either preparatory to returning to Bristol or to shunt the empty stock into one of the middle sidings. The G/F being released by Bath Station SB.

I’ve another one to make for the crossover at the end of platform 1 by the Avon river bridge.

Beyond the fenced area at the end of the platforms was a decent sized circulating area. Mine is about 10mm deep! But doesn’t show badly?

In this picture a lot of the trussing looks white. Its all cream. Funny how the light makes a difference.

Green Park Train Shed Update3   Leave a comment

Following up on Bath Green Park and the buildings.

Here is a better shot that shows the offices on platform 2 and the main station building at the end of the platforms and the myriad of cast iron work and pillars.

These are all real pictures of Bath Green Park that I’ve taken off the Internet and copied and enlarged them to the required size and then pasted them onto my walls.

You can see all the horizontal trussing that Alans brother laser cut for me. This is a fraction of what I have to fit.

Today I’ve started on the pitched roof. Glued the horizontal trussing in place and cut the acrylic (glass) roof panels and fitted the glazing bars onto the right hand one. The other I’ll do tomorrow

Yesterday and today amongst other things finished making the Trussing with Ogee guttering attached that fits along the outside of the side bowstrings on platform 2

About 3’ of it. A bit repetitive! I did the same (without the Ogee guttering) earlier in the week to fit along the top of the wall backing Platform 1 and to which the side bowstrings fit

Regarding disguising the track that crosses the platforms. A single colour is always going to stand out so needs camouflage and I thought about the old train shed picture that has held sway for the last 15 years. Photo copied the centre sections in B&W, darkened them right down and here is the result as fitted to the right hand side. I’ll fit the rest and leave it up for the moment. The other idea is a picture of the station building again in B&W and darkened right down. I’ve only attached it with Prit Stick so easy enough to remove. Once I’ve got far enough to cut out the roof sections and temporarily fit them it will become obvious what is right.

I have the final 5 side bowstrings to make now but waiting on more Plastruct to arrive next week so over the weekend I have those small adjustments to make to the bowstring that is fitted to the station building. Once I have adjusted the width between these two pillars so that it matches all the others I’m then ready to fit this and glue in the pillars on Platform 1

Everyday a lot of detailed work goes on.

I’ve now finished the back wall behind platform 1 and today I glued it in place on the platform. I’ve glued some of the side bowstrings to their pillars. Before I do all the others down Platform 1 I have an adjustment to make to the station building backscene. As mentioned previously I glued the first bow string to this backscene. Measured it all out but somehow the pillars sit 15mm further apart than the others so before this backscene is fixed in place I’ve have to adjust this. Don’t think this will be an issue and those pillars have to be in line.

Once this is done I’ll then glue all the pillars down that far side on P1. Having got those upright and straight I can then glue the pillars in on P2. So the next few days going to be fairly critical.

One of the other jobs started today is painting that front bowstring – the one mounted on Perspex. I started with painting the pillar bases brown. Used masking tape for a clean crisp finish and to test how I’m going to paint this front bow string.

Not great. Paint leaching up under the masking tape – see picture. I used green decorators masking tape! All the others I did free hand and are ok ……… but don’t see myself painting all the beams etc on the front screen free hand. Envisage paint everywhere!

I’ve now got 36 pillars placed. Low down shots on the GoPro really beginning to look good

Big Boy Smokebox   1 comment

Machining does not give a sense of the size especially with such a big lathe. 31/12/2020.

From Alan

a few words about the turning of the smoke box as in the pictures it doesn’t

look as big as it really is. When I made the cage to go inside of it I was surprised

that I was quite accurate with my dimensions.

When it came to turning the sides, at a 3 degree angle, it was all done on the top slide.

It was very time consuming with the rough cuts every 5 inches 10 -15 minutes times 4.

Then twice more to clean up the casting.

Finally 4 x finishing cuts of the sides which took 40 minutes for each 5 inches.

This equates to a lot of very slow handle turning as this was all done 

at 55 rpm.

 Bearing in mind it’s 20inches long and 13 inches in diameter and weighs 150 plus pounds. it’s a lot easer to move with a fork lift.

And still lots more to do.

O Gauge Figures for Alans New Layout 6   Leave a comment

The latest figure to join the group. This fella will sit outside the pub on layout Never Doit, socially distanced from his partner on the other bench. Hand painted with hairy stick.

Big Boy Tender Base and Sideplate Replacement.   Leave a comment

Not being happy with the finish Alan decided to redo them.

To give a better finish the sideplates are being increased from 1 to one and a half mm thick. This allows for a reduction in the number of baffles to allow easier fitting of a high pressure pump.
