Thanks for that matey. Remember the balance weights need to be in pairs, front and back.
I'm struggling a bit at the moment. I have lots of books and pictures and the LMS Journal David Hunt article on Turbo has a simplified drawing of the frames. But what I really need at the moment is a pipe and rod GA. Anyone know where I might get sight of one?
Wish I'd have known that Nick as I was at the NRM on Friday !

Bugger Ian, could have done with those.
Cheers Paul for the great pic. Annoyingly I will have to modify my radiator grille a bit now though!! Interesting to see steam coming from one of the smaller flues in the chimney casting. It has two small flues between the main exhaust vents. The steam is the exhaust from the (steam driven) oil pump inside the turbine casing on the fireman's side of the loco.

......I haven't updated this for a while so here we go.
This shows the oil cooler grille. There is an etching in the kit for the grille bit I used some fine brass mesh I found lying around, and used the etching behind it to represent the oil cooler matrix. HOWEVER (!!!) if you look carefully at the pic above from Paul and Steve you can see that I will have to add some thin horizontal and vertical grille support rods. AND FURTHER you can see that the oil cooler does not stop at footplate level, it extends below it. So I will have to make a new, longer oil cooler/grille assy. (with support rods) and modify the footplate between the frames. The centre of the footplate (between the frames at buffer beam level) starts above the buffer beam and extends backwards only as far as the oil cooler grille. Then it stops!!
On a more positive note below are some pictures of the pipework below the cab. I have fitted up the exhaust and live steam injectors, with their associated pipework. The train vacuum pipe, train heating pipe and the steam brake pipe for the tender are also present. I have just got to fit an outlet pipe for the continuous blow down valve, it has a cooler/condenser coil in the tender water tank and an outlet pipe behind the rear buffer beam (see tender pics above.)
Finally here's a pic of the pony truck with the correct roller bearing axle box fitted up.....

....maybe the last AGH wheels to pass my way so I thought a bit of extra attention was due. Firstly they have the extra bit of webbing round the three spokes adjacent to the crankpins, (following GWR practise and only on 6200/1/2.) Secondly they have the balance weight plates front and rear of the spokes. They are held together with long bolts (represented by 0.5mm rod.) Thanks to Mick D (mickoo) for preparing the etches, see above.

Up to now I have hosted my Area 51 photos on Photobucket (so I can easily paste the posts into the Gauge O Guild's Forum) and my free storage is used up. I don't want to pay for extra, so does anyone know how to post pictures hosted on Flickr or similar?

Yes, just create a flickr page and upload your photos, you can make folders and all sorts of other stuff but for simple use just upload. When setting up the account make sure you select share images, it's in one of the settings so if you can't find it let me know and I'll do a walk through.
Once uploaded select your image so it's the main focus like so
In the bottom right is a curved arrow, called 'share' click this and you get this page
You need to select BBCode and the size of the image you wish to share, it will then give you a url link which you copy and paste into the WT thread like thus.
It'll all look goobledegook like this
until you save the message at which point it will insert the picture at the size you selected with a direct link below for others to follow to see the full size image.
Flickr is free and you can store as much as you ever want, they say you can never fill it up, not sure how true that is but it must be one hell of a server or servers to make that sort of promise.
The only downside is that if you click the picture to make it larger then you get sent to Flickr and do not remain here, that's why I simply upload the photos here, or even better, just use one site....this one of course
Hope that helps

thanks buddy

....right, thanks to Mick it's time for a bit of a catch up.
Firstly I altered the oil cooler screen at the front of the loco to drop below a hole I cut in the centre of the footplate. If you look carefully you can see the frame behind the mesh as the photo above.
The gearbox has been mounted in the chassis...
....and the canon axlebox for the centre driver added (the loco has roller bearing axleboxes,) and the horn cheek stays attached...
...and the brake cylinder/lever mounted...
....and this is what it looks like from the bottom at the moment...
Thanks Mick, apparently you get 1T of storage on Flickr
Brake gear next....

.....also just to update I reprofiled the turbine covers to better match the real thing. I also milled away material from the bottom of the covers to provide clearance for the front bogie. This was done using a dental burr in a pedistal drill, I moved the workpiece around by hand (thanks to Steph Dale for the tip!) Worked though....

....on to the brake rigging. I have installed the brake hangers, shoes and all the rigging.
on to the sanding gear.....

Very neat. Not much room there for the cross shafts etc.
Nick Dunhill

No Peter it is all VERY tight. The gearbox has a depression in the bottom to provide clearance for the cross beam. (I wasn't really sure what it was for while I was making the gearbox!) There is very little room for the pull rods between the sides of the gearbox and the axlebox springs and hangers.
