Hello All,

for anyone thinking of one of these with CSB suspension the weights are,

 

Engine; 2lb 2 1/2 oz or 980 grams.

 

Tender; 14 1/2 oz or 416 grams.

 

Just getting ready to ultrasonic clean the engine body.

OK I give up what did you do with the rest of the frames? biggrin.gif

 

Superb work, very envious of the finished engine. I'm sure your Castle will be even more entertaining...which one is it?

Hello Mike,

if you mean in mess #74 that's in next months part work.

The loco will be 7099 one of Cantons finest (apparently, sorry Steve). There's a lot of work been done on the Castle build already, so when I get started on it I'll just do some photos just to highlight some points (or do yous want all the gory details?).

Hello All,

just getting the Baby Castle ready for all the final test etc., but to keep you entertained here are some photos of a Castle bogie under construction.

 

The bolster with the dummy side control spring fitted. These are real springs but don't do any work.

post-8920-0-34525400-1300280640_thumb.jpg

 

The bolster with the top bar frames fitted, before fitting the bar frames clean up for the horn blocks, and mark them 0-3. Drill and tap the hole through the top frame and the bolster 12BA.

post-8920-0-55314700-1300280669_thumb.jpg

 

The frames with the front and rear strengtheners fitted.

post-8920-0-20745300-1300280761_thumb.jpg

 

One of the equalising beams, the hole in the center is a blind hole for the spring (Slater's horn block if I remember correctly).

The bottom frames from above and bellow.

The completed bogie with the center pivot and bearing pads in place.

post-8920-0-25750800-1300280878_thumb.jpg

 

The completed bogie painted and wheeled up ready for fitting.

post-8920-0-82432100-1300280913_thumb.jpg

 

This bogie is from the S.D.K. In the normal kit you get a version in etched nickel silver.

In my opinion it is worth the extra money for the S.D.K. for the extra casting that you get. When I get going on the Castle build proper I will let you know what parts are from the S.D.K.

Hello All,

this is part of what the loco has to put up with. Not the best photo in the world, but it gives you an idea of the test track that I use. If the loco will run on this it should run on anything.

Hello All,

during my clean up and testing I came across a small problem. Now I know that I should have spotted it earlier but I didn't. When I put it on one of the few bit of flat track that I have that I know is flat, it was rocking, and it had a tendency to be a bit lumpy through the frogs of the double slip. When I took the front wheel set out to clean the plunger and axle box's I could see rubbing marks on the bottom R/H slide bar. Now I was to far on to move the slide bars. What to do?

 

Well our axles are to big to start with. 3/16" = approx 8" and most axles are about 7". 9" on the journals. So if the real axles can have a slim bit in the middle why not.

 

So lets turn the center section down a bit.

post-8920-0-59087100-1300370230_thumb.jpg

 

The chassis ran well before but it now runs better.

Building a kit is not just about putting it together, but when you have a problem knowing how to solve that problem as well.

Hello All,

as I said in my last post on the 2251 build "now the end is near" and it is, the loco is finished all the tests are done. So hears the last photos of 2230.

 

When I had put some primer on the loco body I spotted this, it's some epoxy that had squeezed out from when the saddle was fixed in place, now do I leave it and say nowt, or do I remove it?

post-8920-0-56116600-1300448759_thumb.jpg

 

Well I think you know the answer, it had to go. In these photos you can see my idea for covering the gaps in the steam and vac. pipes where they cross the frames. Not elegant but it works.

post-8920-0-90879700-1300448816_thumb.jpg

 

Well this is what you've all been waiting for the final four photos of the completed loco.

post-8920-0-75338600-1300448889_thumb.jpg

post-8920-0-90350700-1300448975_thumb.jpg

post-8920-0-05313100-1300449051_thumb.jpg

post-8920-0-42595300-1300449118_thumb.jpg

 

There are some differences from the build photos in that the slacking pipe has gone (the owner didn't wont it fitted), the steam heat bag end is a bit shorter.

 

Now to summarise; would I build another YES please, are there a lot of problems with the kit NO; is it suitable for a 'first loco build' Yes (as long as you've done a bit of building before). The resin boiler and the tender tank takes a lot of the big pit falls out of this build. If you didn't feel comfortable about having the valve gear to work it could be assembled static.

 

Not sure if I can put this here, but here goes. If you would like a CD of the photos of this build PM me, the cost is £5.00 including P&P.

 

Happy building

 

OzzyO.

 

PS, off to re-start work on the Castle 5099 not 7099.

Hello All,

I was going to retitled this thread, but I can't remember how to do it!!! (so if someone can tell me please do so).

To start with some photos of the Hawksworth tender for 5099. This tender has had some modifications to fit a sound chip and speaker into it. I'll be doing a full Hawksworth tender build soon.

 

The tender top before mod. This ones for a County so it's a bit (6") wider.

post-8920-0-16314800-1300703337_thumb.jpg

 

Two views of the Castle tender top.

post-8920-0-15209200-1300702480_thumb.jpg

post-8920-0-51246900-1300703619_thumb.jpg

 

The inside of the County tender top.

post-8920-0-82540700-1300703437_thumb.jpg

 

To try and show the mods. to the Castle tender top, to get the speaker etc. in.

post-8920-0-99057400-1300703537_thumb.jpg

 

The County tender chassis with I think the inner chassis in place. (Its not)

post-8920-0-37147300-1300703787_thumb.jpg

 

The Castle outer chassis with the mods. For the speaker etc.

post-8920-0-37535300-1300703685_thumb.jpg

 

Front and rear buffer planks with most of the fittings in place, the intermediate buffers are sprung.

post-8920-0-97627500-1300703859_thumb.jpg

post-8920-0-83606700-1300703920_thumb.jpg

 

The front of the inner chassis, showing the front brake shaft. The front brake shaft end bearings are on the outer frames and the shaft has to be cut just inside of them so it will all line up when the two are assembled.

post-8920-0-79586100-1300704228_thumb.jpg

 

Three views of the inner chassis. The front and middle axles are sprung and run in tubular bearings and pick up current from one rail. All the bearings are insulated so that the chassis is netural.

post-8920-0-69732200-1300704184_thumb.jpg

 

The inner chassis from the top. On the upright board you have the pick-ups from the tender and pick-ups from the loco, which go to the chip. Then at the top you have the feeds from the chip going to the loco (not fitted yet). You can see two jumper wires going from the bottom of the board to the top, these are for testing purposes and will be removed when the chip is fitted.

post-8920-0-10499300-1300704003_thumb.jpg

 

I will be doing a full build of one of these tenders when I start on the County build. So if yous want a full photo build let me know. That will be in the next month or so.

Hello All,

now I've got this retitled I don't mind to much about putting some photos on hear.

The Castle build was put on hold for a while, to get some other work done. But this is how far I'm on with it.

Hey Ozzy won't it be exciting when you can change this thread title to MOK 71000 duke of Gloucester build.( for me )

Mok are asking for suggestions for new kits in 4mm and 7 mm it seems the duke is going to he released. There's a thread running on the suppliers page and you can contact them via there web site.

Sorry for the hijack but the better quality kits we have the better I think.

Hi OzzyO,

 

As a result of my enquiry about help on building class 2251 tender I have been directed to your link.

Just what I wanted so thank you.

However can you tell what sought of clamps you used to hold the coal raves in place and where I could purchase.

The pictures are great and help together with your remarks, although I shall not go for split axles etc.

Look forward to your reply

Kind regards

Keith

Hello Steve, Keith, All,

 

I've fancied building on of the MOK kits for some time so the DoG will be most welcome. As you say Steve the more high quality kits the better.

 

The clamps are just "spring clamps" I got them from my local tool stall in the market IIRC £1.75 for six, if you would like a set let me know. The market opens Mon. Wed. Fri & Sat.

 

Or you could modify some spring clothes pegs, cut the curved ends off so you get a nice square end.

 

Now is the time to get a brew and settle down, this is the front end of the frames, most of these photos were taken some time back on my old camera.

 

The frames folded up and tapping the pivots 10BA, the front vertical plate will have been drilled 2mm for the piston rods, I'm now using some small brass top hat bearings in here now.

post-8920-0-98386100-1302423329_thumb.jpg

 

The cylinder former folded up and two 6BA nuts soldered in place.

post-8920-0-94743400-1302423375_thumb.jpg

 

The cylinder former and front frame spacer soldered in place.

The inside piston rods

post-8920-0-34642800-1302423710_thumb.jpg

 

One of the rocker arms, I do some small mods to them a brass washer is soldered over the center pivot hole and a short length of wire is soldered across one of the arms to form a 1mm hole.

post-8920-0-92259900-1302423750_thumb.jpg

 

The top of the middle of the cylinder stretcher is removed and cleaned up.

The same loosely in place.

post-8920-0-47849600-1302424607_thumb.jpg

 

All fitted in place and pined together. On this loco the movement is transferred by a U shaped length of wire soldered to the valve spindle.

post-8920-0-37463100-1302424698_thumb.jpg

 

This is how I now do it, a small block of brass is drilled for the spindle and cross drilled for the movement transfer lever.

post-8920-0-17632000-1302424776_thumb.jpg

 

The out side crosshead the piston rod is drilled 1mm for a brass pin.

Excellent thread OzzyO. Not a GWR man, but great to read how this is coming along. Fully condone the use of Maxon motors. Think I was one of the first to go this route and certainly remember supplying my own motors to ABC before they started to offer them. Also good to see some of your own techniques and fixes to improve the kit. :thumbsup: (can we have that emoticon please ?)
