The Frames look terrific, Dougs. All well worth the effort, I'm sure you will agree.

not had much time on speedy but I am still working on her design when I have a few mins so I thought it was time to update you on the progress of the axelboxes,
to recap these are the problem

they have the bearing bushes in the middle which is not good as they are about 1/4" too low
these are the ones I have vs the original design which are split and will allow removal without "splitting the axel"

so my new solution is to make some brass bushes and incorporate them into the original design so they will split allowing worn bushes to be replaced if required.

its not a fantastic picture but basicly I make a split bearing that will fall into the original design quite nicely I do like simple solutions, it makes them less likley to not work.

Looks to me like your going well with your build.

is now the right time for me to reveal i'm about 6 months into a very long build of a 5 inch gauge model of Robert Riddles finest Loco, the standard class 9 or 9f?

[Dan4th]

Well then show us some PICS

C'mon, Vulcan Bomber, Pleeeeze????

Seriously, I'm sure we'd all be interested....

I've not taken any pics of anything yet, when theres bits worth looking at I might start a build thread of my own.

[Dan4th]

If you start a thread, we will all
be watching and having fun like
we do with Dougs, so please do
it if and when you can

Not "Aircraft", but still fun!

Can't wait to see that vb I am now going off to google the class 9
And I'm back wow that's a monster 2-10-0
Is it your first loco?

Yes, the 9f is a big loco at the best of times, the most powerful steam locomotive ever to run on british tracks. One holds the record for pulling a train weighing in at around 2300 tons according to its owner.

It is my first engine (nowt like jumping in at the deep end). I am actually a cnc machinest by trade so i havd access to some really clever kit at work and most of its produced from waste material from work. I'm very lucky in that respect

[Dougs]

I have to say I am quite jealous a cracking loco, it will be amazing when built. If you need any help at all you know where to find me I am not an expert by any means but I have got to know my way round a model loco reasonably well.

[Dougs]

I have been progressing slowly with the new axle boxes
First job was to cut the bushes out

Next to machine up the faces

One down one to go


Both done from the center axle

I also went to the midlands model engineering exhibition today and although they did not have any speedy's they did have a 7 1/4" gauge version "paddington" wow



I could have spent all day taking photo's of it absolutely lovely model
Anyway I got loads of materials to continue the build including all the bits I need to make the axle boxes and finish the frame.
I also got some authentic paint to do a full respray on butch but that's for another time.

Krikey!

How many men does it take to
MOVE that thing?????

Lovely piece of work, though

Quite a few
I would estimate about 160kg or 350lb unbelievable heavy

Thank you for the Update, Dougs. Also for the pics of that beautiful model Locomotive. Fantastic!

[Dougs]

slow but steady progress i have almost finished the first axle box got quite a bit more milling to do then bore the hole for the axle but its definately getting there

[34053]

Thank you for the Update, Dougs.

Been back at building my loco again having now got my restoration out of the way
Finished off the prototype Axle box

I was told the best way to make multiple parts was to work as if I am doing a batch so I set about doing some milling operations to progress the other five axle boxes so got the parts all cut to size

I then got all the others to fit nicely a lot more machining to do to finish them off but a good start

[Spitfire]

Brilliant ... what skill you have

[Dougs]

Brilliant ... what skill you have

Thanks, you should see my scrap bin

[Aceyone]

Fascinating stuff,when I think I used to struggle with Airfix models !

[Dougs]

Spent all day machining and feel like I didn't get far but these axle boxes are very complex and the more accurate I get them the better I will be off later on when I get further into the build,
So with a new batch job way of working planned out I set about machining up the boxes

The groves hold the brass bushes in place

And it's repeated on the top bush

All lined up ready for final machining to size note the peg drilled in the side to hold the whole assembly together

The first axle pair machined and fitted to the frame

I still have to bore the hole for the axle and drill a couple of holes for the spring pins but getting there.
On a slightly side note all this very laborious machining has inspired me to fit a power traverse to my milling machine so I have bought a motor and speed controller from Ebay and will set about making that when it all arrives should make milling a lot more fun.

Nice work there.

Your not going the whole hog then and making it into a CNC machine??

[Dougs]

Hi VB no I decided not to bother as I like to do the machining myself where possible and the programming will take longer than just doing it anyway as most of the parts are generally one offs. CNC wise I have access to 5 axis grinding, milling and laser cutting, laser drilling and laser milling oh and some EDM machines too, at work so bit pointless spending time and money to make a very cheap version of a CNC machine.
I quite like the pain and effort to do it the "old way" even though my grandfather was horrified by my use of scales on my lathe and miller an awful lot of bits are available now from suppliers ready made, but I don't want to build a kit. I want to make as much as I can, and in the case of the axle boxes make my own design if I feel it's doable. I personally don't think there is a wrong way as I do it for fun. If someone wants to build from CNC parts and they enjoy it then that's awesome. For me it's the making that is the best part I am luckily in no rush to get finished, although I have just got some plans for a traction engine

[34053]

Many thanks for the Update, Dougs. A 'Traction Engine'.......................................I just Love the thought of that!

Thats fully understandable.

Some reading here for you if your interested?

And just so you know, there is now a 9F on the GCR to live.
