Whilst waiting for some paint to dry... I've been cutting out the frames from sheet steel. I have a lifetime supply of 1.6 mm

It's hard work with a hacksaw. Filing the edges flat was aided with a long straight edge and sighting through.

Here's the frame blanks cut to length

I've been cutting those lovely cut-outs in the frames, lots of sawing and filling. Then lots of drilling for spacers, and heaps of 8 BA tapping in the spacers. I start the tap square in the bench drill. But, first I remove the quill return spring...

Filing, filing

I've been working on the buffer beams. The chassis is bolted together. It was nice to do some turning again, the axle bearings were turned yesterday from gunmetal.

I couldn't resist sliding the wheels on

I've a supply of 8BA screws from my local supplier.

The buffer beam height is perfect for the LGB stock...

At last a rolling chassis. The coupling rods are finished. I shaped the cranks in blocks of two blanks soldered together, the profile is a bit different between the pairs, so I'll put each pair on their own side of the loco, and not mix them.

Checking the clearances

Rolling chassis

This is how I modify screws. I needed 1/4" AF for the cranks, to keep the rods on, but had no bar stock. I converted four 4 BA screws into 8 BA

Now I need to think about the cylinders...

Wow this is all looking really good, I'm following this with great interest

A month ago I made a gentle start on the smokebox as I wait for some cylinder materials. I'm using steel sheet for smokebox endplates and wrapper

Here's the progress so far. I like using roundhead screws for the rivet look, these were used on the live diesel bodywork

Last weekend I started on a flange to mount the boiler barrel to the smokebox.

Disc blank cut out and mounted on mandrel

Outside diameter turned

Centre removed and bored to just pass the boiler barrel OD. Strip cut out and filed flat.

Strip bent to shape around a handy former. Ready for silver brazing

Fully brazed. It took many heatings and adjustments to get the strip placed just right. My first go with cadmium free silver solder

Although a little heat distorted, I was pleased with the concentricity

One week later, boiler barrel fitted to smokebox. 8 BA all the way

Hi Dave!
Nice job, be interested to know what you thought of the Cadmium free silver solder, assuming you have used the cadmium stuff before. Hear many reports of it not flowing as well as the old stuff.
I'm afraid I have enough of the cadmium stuff to see me out, so can't see myself changing, but be interested to hear your opinion.
Grant.

Hi Grant, the cadmium free went fine. My old silver solder will soon run out, so I bought a stick of the cadmium free to try. The ring had two spots where it had pooled, I think at the end of the flux line, and me over enthusiastic stick feeding. When the job was finished, I re-fluxed and re-melted them and it flowed nicely without any other aid

Thanks Dave, I reckon your a game man soldering a ring that thin and then machining it to fit. Concentricity doesn't have to be far out when you involve the lathe. Congratulations.
Grant.

I made the chimney base from steel. One of the first operations was to mill the smokebox profile on its base. I did this in the lathe, with my old Emco Unimat 3 flycutter.

After milling, the blank was turned in the lathe, working both handles to get the large radius.

The job is secured to the mandrel by Loctite 609 retainer

Lots of heat is required to remove the job from the mandrel, the chimney base is now a lovely blue/black colour

It certainly is a pleasure to see the work in progress. It looks like a fine job so far. I am particularly impressed with the boiler/smokebox flange.

Thank you Keith!

Moving to the other side of the smokebox, the smokebox door. This is made from a slice of free cutting steel soft soldered to a mandrel after the rear face was turned.

Rear face details just visible

Profiling the front face

Finished door still on mandrel

Hinge straps cut out of 0.6mm sheet with tin snips

Finished hinges. I used LBSC's "words and music" for the straps and lugs. I had to borrow the roundhead screws from the live diesel

The door is swinging!

Dave,
The big problem with your work is that I ran out of superlatives long ago! As always, I'm in awe.

It was time to start on the chimney. I started at the top.

Gunmetal was used for the chimney cap. The blank was Loctited to the mandrel

Marking out the upper curved part

I filed this curved surface

Rough turned

Finish turned

Tall chimney version

Cross-bar fitted

Out on the line!

It was a lovely morning for a cigar and coffee!

I made a start on the cylinders. I like to use commercial plain bronze bearings for oscillator cylinders. They have a very good surface finish.

The port faces were bored in the lathe using the exact same set-up as was used for my large de Winton. Bored for the cylinders to be able to be soft soldered to them.

The faceplate required counter balance weights

The port face is soft soldered to the faceplate angle plate

I want the rear covers to be removable. I like screwcutting so decided to thread the end covers and the cylinder. An internal tool was ground for the cylinder, this took days... I've used 40 tpi as the pitch. As the threads were short I turned the chuck by hand. My wrist was aching like a teenager's afterwards!

I thought I'd tackle the boiler next so that I could see where everything will go. I've been very slowly progressing.

A supply of 1.5 mm copper sheet, 2", and 1/2" copper pipe was already on hand. I've recently received some more sticks of the cadmium free silver solder (brazing rods) from Macc Models, I'm ready to make a sizeable investment in the boiler - lots of silver.

Some 4 mm thick steel was bought to make flanging formers. I was able to reuse a boiler endplate flanging former from my first loco build; the small De Wintons. Flanging is very satisfying with frequent stops for annealing the copper sheet.

Rounding off the throatplate / backhead former

Rework #1: Removing a thin strip from the wrapper using the piercing saw. The throatplate is already brazed in place.

Backhead and former

Firebox former with unformed plate

Progress so far
