Thanks guys for the comments and likes.

Lining proceeds, the loco body lining is coming to completion except that I am running out of decal lines, there is no decals for the valance curves and for the cab front at roof level! I have just enough lines to complete the tender which involves trimming boiler bands (which a few extra were on the sheet) of one of the yellow lines.

Valance lining with the bow pen- black line done.

Setting up a cab front line on clear decal paper- black line done.

Tender lining complete and getting ready to epoxy on the axle boxes, buffer shanks and vac pipe.

The inside of the frames were abraded with a fibre pen back to the metal for best glue fixing.

Tender chassis with breaks fitted.

The tender is now ready for a few coats of lacquer.

And these are the parts for coaling the tender- a folded styrene cover for the coal chute, a bit of MDF to fill the gap under the coal, and a card base for holding the coal, these will go in after lacquering.

Yellow lines going on the loco valance, I got this paint mix a bit light but was chuffed with the neat line so decided to leave it there and dull it down later.

After making an adjustment to the paint mix I did the yellow line for the cab front.

Looks brilliant thanks

Marking Dart handles for the smokebox door.

Making the handles out of 2mm brass tube, 1mm brass wire and a 12BA washer.

The brass tube will form the main body and is held in a collet chuck with a hexagonal body for indexing in the mill vice while drilling .6mm holes to take the handles. One can just about see the two holes in the end of the tube, this end is then cut off in the lathe using a fretting saw while the tube is rotated.

Two pieces 20mm long of the 1mm brass wire is cut off and mounted in the mini drill for filing the taper of the handles down to 6mm dia, the brass is rotated against the hardwood block while the filing is done. When the filing is complete the handles are trimmed to 8mm and 5mm.

All the bits ready for soldering, a 1mm brass rod will go through the tube body and washer, it will protrude out the back for gluing to the smokebox door.

Jigged up for soldering with a small spot of 180deg solder, the 1mm wire protrudes out the front and into the timber base to hold all in place- this is cut off after soldering. Flux is liberally applied to the parts and the soldering iron is only touched off the wire above the washer, after a second or two the solder wicks down through the assembly.....

......and done with protruding wire cut off.

After a wash and clean up with the fibre pen the unit is acidip cleaned and acid blackened.

Finished part.

Parts being epoxy glued on the loco body, the name/number plates are stuck on with Glue n Glaze.

Decided to install the card base for the coal now so that it will get a good lacquering against the Mod Podge glue sticking the coal in. The coal chute has it's baffle epoxied in and the mdf spacer stuck in with Sticksall adhesive.

And the card is stuck in and sealed around the edges with Sticksall so the glue hopefully wont leak down through the model- best to keep it in the coal!

 

And then with nearly all bits stuck on a test assembly of the loco & tender to check for adjustments n jiggery-poke- to be done before lacquering just in case finishes need touching up, the tender footplate height also been checked for a few mdf spacers to bring it up level with the cab footplate, and setting up the tender drawbar fittings........

 

 

.....and maybe a few more;-

Still have to tone down that valance & the cab front line, a tad bit heavy also and thinking about what could be done!

The gear n wheels to drive the oil pumps also needs fitting... and a few other bits.

I think were pretty close now- to the end!!

Thanks looks wonderful 

[popeye]

Love it, it would be nice to see it running.

Thanks guys, the best I can do is show it running on the rolling road very soon.

The crew were by yesterday on inspection and set about preparing the coal....

Can't beat real coal, they look like a couple of tough nuts.

That is a museum quality piece that should be on display at a national railway museum. Stunning model engineering, absolutely sublime build and exquisite finish.

[murrayec]

The last mechanical parts are complete;-

The Tender drag bar was set-up with a brass tube collar to capture the bar and allow to rotate.

The oil pump drive gear was cnc cut from .35mm NS sheet and brass handwheels cut from.3mm brass sheet, the parts were cleaned up, holes sized, and then prepared for sweat soldering.

Parts are now soldered and ready for installing.

Test fitting the handwheels to the pump box with 14BA screws.

.8mm Steel rivets were used to assemble the gear.

All the bits ready to go on, using a sleeved 1.2mm brass tube as bearings and more 14BA screws.

And done both sides.

Amazing detail!

 

[DB JOE]

model engineering par excellance

[murrayec]

The model is now complete.

The cab window frames and glazing were finally installed after the body was given two coats of satin lacquer.

The lads posing again!

Then final assembly to take a run on the rolling road.

I'll post up a short video soon.

Absolutely excellent result Eoin. Total class. Stunning precision.

And some live action

 

[Sean Hogan]

Well done eoin will be in touch about collection.

Eoin if the country doesn't end up in Level 5 lockdown until next May, you might bring her down and run her on WMRC's vast Little siddington O gauge layout. She looks amazing. She'd put the A4s and BR class 37 diesel locos in their place pretty quickly. Stunning build.
