Ralph Brammer models

For discussion of the issues faced when building a model or layout - how to replicate wood, what glues to use, exactly how much weathering can a Gnat take, a good source of detailing accessories - you get the picture, I'm sure.

Hi Gerry
I must admit I did think about commercial gears, but I thought that by the time I had huntered them down I could produce the style I needed.

The layout I am afraid is firmly built into the gararge and is not designed as a portable one. But if it interests folk I will keep poping pictures on the site. At the moment most of the work is done in my work room (glory hole) in the house and the finished bits will be taken to the gararge as and when they are completed.

The Norfolk (and Suffolk) boys are a great help in acting as a sounding board for the development of its overall plan. We have informal Gnatter meeting now and them to exchange ideas and show each other the latest goodies. It seems to work well.

If you are coming to distant parts(Norwich )let me know and drop in. I hope to make some progress over the next few months.

Hi Ralph, That is a most impressive bit of gearmaking the most amazing part is getting the last tooth to be the right distance from the first. Not an easy task if you are off by even a cats whisker :!: Having taken the time to machine gears with an indexing head, and even that can prove to be a challenge for the above reason, I am most impressed with your talent and patience.

Fine bit of work that is Lad :).

Hi Michael

Thanks for your comments. Dont look too closely but one tooth on the large cog is slightly thicker than the rest :roll:

What interested me was that I found the best way was to use the old method used in water and wind mills for wooden gears. I used the peg and spacer block method which gave me eaqual(almost :D ) spaces and supported the teeth upright.

Next step is the two cheek uprights and an effort to put the axles in the correct places for the cogs to mesh :!:

An interesting problem

Regards Ralph

Hi all
While sitting in a Travel Inn on Saturday ( more about that later :D ) I saw these ntwo pictures of the crane at the tran-shipment dock.

It looks very interesting if only somebody could move the two locos out of the way so I can get a better look. They can shunt them back again afterwards :? :?

Interesting thought :idea:

crane

Postby Rockley Bottom » Mon May 21, 2007 7:48 am

Hi all

The side panels for the crane finished at last. I nearly made them a pair instead of being right and left handed :oops: but woke up to the mistake in time.

Good job they are on opposite sides of the crane as they are not a perfect pair.

Hi all

Double sided tape mock-up :!:

Thought I had better see how some of the bits went together. :?

Got the jib support done, as well this (as the crown pivot) will be a two piece casting to allow for flat back casting, Just idle :roll: as I could cast them in one piece with a two piece mold.

Think you need to have words with your brick layers Ralph, or is this a bond that I'm not familiar with :lol: .

Good to see you are progressing so well with the crane. I must admit, until you posted the pics, I didnt think of the similarity with the one at Balderton on the Eaton Railway, a location that I have often thought would be ideal for the basis of an inglenook type shunting layout :wink: .

Hi Steve

Good to see on Saturday in a strange country so far from your base :D

As you must have guessed it either ment lifting the brick paper or turning it on end

The easy way out won :!:

Ralph, the crane in your pictures is the transfer crane at Balderton on the Eaton Hall Railway. The photos were taken in 1905 when Little Giant arrived for trails there.

Hi Peter

Thanks for the picture What atmosphere :!:
It makes me think a transfer siding is a must, even if it is just to model the two blokes in the picture :)

Thanks Andrew, now comes the messy bit doing the casting. Must NOT ruin any more clothes :oops:
I have some casting gear,trousers and sweat shirt which stands up on there own with resin.

If you find that interesting you should check out Mark Smithers' book Sir Arthur Heywood and the Fifteen Inch Gauge Railway. It has much clearer versions of all those photos.
Also (If I recall correctly) somewhere on the internet there is a picture of the Jib crane at Duffield. I can't find it right now, but I'm certain I saw it in the last year or so.

It's a small world, that is Simon's layout (rue_d_etropal) :) , so come on Simon, where did the crane come from :?: is it the Pola one :?: .

Hi Peter

The pictures I used to send to the group came from my copy of the Heywood 15 inch line.
It probably lost some clarity in the scan. :?

Thanks for the link :D

I heard of one mine in South Africa that tells guests they can keep any ingot they can carry... I think they've lost one in their entire history that way...

Mind you, how would you get it through customs :D

Brickwork

Postby Rockley Bottom » Thu May 24, 2007 8:05 am

Hi Steve

The builders said "thanks" for the tip about the bonding and they will try to remember it for next time :oops:

It is also not true that the extention is so I can take over more rooms for railway modelling :shock:

It might be an idea thought . may just get bunk beds in the alcove :?:

Regards

Ralph

Hi all

I made a mistake :oops: :oops:
The error was in my guess at how the gears meshed. The drawings shows what I did wrong :evil: This was because I thought that I "knew it all" instead of checking and checking again.

At first I thought I had two options, to make a new big gear :!: smaller than the one I had made so that it would fit into the distance I had between the bearings.

The second option was to make a new side :!:

I then woke up in the night and thought that I could extend the sides I had made. The trouble is the sides are triangles.

I then remembered how my mum extended the sleves on my school shirts during the war. she added a "T" shape into the sleeve to take care of the tapper in the sleeve.

Bingo :o this was the solution the second diagram shows the solution.


The two pics show the first castings of the crane.

If you do not look too closely " you will not see the join" :?:

BURTON-ON- TRENT SHOW


Hi all

Something I ment to mention was the presence of Gn15 at the 7mm NG show at Burton-on-Trent last week.



Steve Bennett was there with his stall of goodies and his layout which drew peoples attention to our scale. It still looks great every time I see it and has many lessons to teach in scenery building etc. It has a "total" look which I find brings a model to life.

Gerry Bullock had his salt pans on veiw and was a great hit. It looks good in pictures and even better in the flesh. His stand was a meeting place for several Gn15 modellers who had made the trip to Burton including Pat and Dave Westall. Gerry's layout had something moving all the time and the wind pump took my eye.

Gerry has put a lot of work into the extention and alterations to the layout and it is coming together very well. Next time he must wear his salt workers hat, :shock: if the ones on his figures are the correct style it would go down a treat :D

I had a great day out and the bacon butty was first class.

Can we get a few more Gn15 style layouts in to future shows :?: :twisted:

Thanks fellers for all your efforts


Ralph

Pretty impressive fix Ralph, Are those the same pieces that you made originally? they almost look like castings, they do not look painted if that is what you did. What paint did you use and how?

Hi Michael

You are spot on they are castings :D
I suppose that it is habit from the days when I sold castings,and I may need another crane later on for the railway.

I never liked making more than one piece (I find it difficult to get a matching pair :!: )

I have been making the other bits for the crane today, the wheel and fittings for the end of the jib, the winding drum etc.

Will show the progress as i manage toget it all together.

The method I use for painting is to wash the castings and brush with an old tooth brush. Rinse, dry, spray with car primer, and spray with colour or brush paint. Add lettering or/and home made transfers, spray with matt varnish. add weathering etc before varnihing.

Hope this helps

Regards Ralph.
