Thats a very groovy footplate Col
Lovely build.
Steve

Thanks Steve, I used round bar of various sizes to get the shape right.

That's come on nicely Col, and the chimney's a corker!

A brilliant piece of work. Is the chimney a turning or rolled from sheet?

Cheers, the spark arrestor is made from 0.010" nickel. Once I worked out the dimensions each cone starts as a ring of sheet metal, polo shape basically, make a radial cut through it, and then gently curve it with my fingers over a round bar in the vice. The central flange is a flat ring of 0.010" again, then soldered up.
The lower part of the chimney and the dome were fly cut on the lathe to suit the boiler and smokebox dia's and then turned in the lathe, the chimney being bored right through.

Absolutely beautiful mate!!

That is just lovely, I wonder why the designer positioned the spectacle plates relatively close together?

Looking forward to seeing this progress

Fantastic work Col. Are the rivets on the bunker back embossed or scale hardware? I only ask as they seem much more heavy duty than the footplate top? I'm still learning with my GW press and it's trial and error with the different size tooling and depth of rivet etc, any pointers would be greatly appreciated

Another job rubbing shoulders with the others is this unusual loco.
It's a 3'-6" gauge Beyer Peacock 0-4-4 built for the Norwegian Railways, a rivet counters delight

Pimply brutes, those Beyer Peacock engines... Is this going to find its way to Fangfoss by any chance?

Hi,

Fantastic model of an interesting prototype. Similar locomotives ran in South Australia on the same gauge track.

Indeed V9 plinthed at Naracoorte is the oldest preserved loco in SA, I note the cab is a bit more open than the Norwegian one.

Simon,
I must admit this area of the cab was difficult to ascertain as I did not have an end elevation drawing and the plan did not show this detail.
I had to try and scale it off of a photo ( see below) but also I wondered that with a relatively small dia. boiler/backhead and with the regulator in the middle the driver would be standing closer to the center than the outer area of the cab, so to enable them to see forward would place the spectacles in that position ?.

Mick,
The rivets are all done with a G.W. rivet press, it's as you say trial and error. I test on a piece of scrap to see how they come out and then compare to the photo's.

Richard,



I was asked to build with slightly different chimney to the one shown above.

Quite a bit rolling through the bench at the moment, here's a little Ixion Fowler 0-4-0 Diesel Mechanical.
Converted to S7, (what else ) and weathered.

How did you do the conversion? What "new" parts did you need?

thanks, Graham

 

[Steve Cook]

Very nice Colin, that has a great 'lived in' look and the pooled water is brilliant

…. What "new" parts did you need?

thanks, Graham

I'm guessing used notes would be just as acceptable.

.................. I wonder why the designer positioned the spectacle plates relatively close together?

I would think it's because the loco was built without a cab, but with a forward spectacle plate just like the aft one in the picture.

Then later - when the cab was installed - more platework was added, but the portholes were left in their original position.

Unlike the Ixion Manning Wardle, which had stainless steel tires and 3/32" axles, this one had brass tires and 3mm axles which made life easier.
Once I had taken the chassis apart the axles were removed and the wheels pulled off using a G.W.puller. I then turned up some mandrels to suit the wheel dia.
The wheels are held in a set of soft jaws by the tread of the tire( flange outwards) and the back of the wheel is skimmed, in this case by 0.5mm to bring the flange down to about 0.7mm width, which gives enough meat for the S7 profile tool to work on.
I also first checked that the tire would not be turned to thin for S7 standards, for loco's 3.2mm approx and I didn't ( couldn't) want to take any material off the front face because of the detail, boss and balance weight.
The Ixion wheels are quite coarse so no worries there for re-turning.
The above mentioned mandrels are then used to mount the wheel in the conventional jaws and the wheels re-profiled.

There was no need for new axles in this case and the wheels were re gauged and quartered.

Been a while but then it's been hectic to say the least, but finally finished the little Beyer Peacock.
She is a total scratch built to 7mm scale, 3'-6" gauge, and to give an idea of proportion she is just under 7" in length.

Powered by a Mashima motor mated to High Level gear box altered to fit 3/16" insulated axles which in turn were adapted to take the Slater's wheels which are designed for 1/8" axles . Sprung axle boxes, compensated bogie fitted with side control springs.



.....on to the next one, no peace for the wicked

Lovely model of a pig ugly prototype

Your gonna hate this but with a chimney like that (standard wood burner chimney with in built spark arrester) and being Norwegian I'd put a lot of money on it being a wood burner, not coal

Like Sweden and Finland, Norway has an abundance of wood and has to virtually import all of it's coal, so many smaller engines (Sweden and Finland still used modern large wood burning 4-6-0 till the very end) were wood only and it's why Norway was one of the first countries to go electric.

I'm sure you're quite right mate although I have a photo from my client showing a coal burner with the very same chimney. I'll will ask him about this though.

Lovely mate,

Always inspirational to see a pure scratch build!
