Recommended Posts

A Kelly/Hamil Gauge O 0-6-2 Tank Loco was in the workshop for coupling rods, wheel weights, and break gear upgrades;-

On arrival

After the survey & research was carried out a drawing was prepared to cnc the main parts from .5mm nickel silver and Tufnol for the shoes.

All done and cleaned up

The coupling rods are made up of 3 laminates, a jig was prepared to hold the laminates as they were sweat soldered together. Aluminium rods to appropriate size were inset on the jig board, the parts were covered with 180deg solder, then clamped in the jig, fluxed n heated until all laminations sat flush and soldered throughout.

Break gear prepared and ready to go on the chassis

A new NS wiper pickup system was installed to recess the boards and give clearance for the break rod gear- the chassis is a bit deeper than it should be and with the original pickup system would have pushed the break gear down pretty close to track level!

First run- with a bit of tweaking!

Repaint? Green or grey?

Nice either way - the above green is too light.

Nice model. Love to see an 0 gauge loco like this in action.

Hi jhb

As far as I know that's it's colour, it's now just the chassis and new bits that require painting.

If your free in the morning there is an open time in the MRSI club from 11.00 to 2.00, the Gauge O Guild meeting is on at the same time and the above loco I'm sure will be run, also the T2 from my other post, and other Gauge O stuff......

Eoin,

 

This is looking good - coupling rods look excellent.

I'm currently working on one of these in 4mm & have drawings, so could have helped with the research!!

Difficult loco to build due to the different levels in footplate, wrap over cab roof, curve in the smokebox front, and very interesting bunker area.  Quite a challenge and a very enjoyable build. 

 

Some small problems with drawings which need some amendment to fix some issues.  The position of the front curve in the footplate is in the wrong position on the drawing which has impacted on the front splashers, pushing them too far forward - should be relative easy enough fix though.

What is nice to learn is the relative size of locos.  Read as many books as you like, but when you see locos on the track you get the true scale. 

What is noticeable is how big the 670 locos really were - they really fill out all available space on the footplate.

Probably a bit late to offer assistance, however if there is any more info I can provide, please do get in touch.

Hi Ken

Thanks for offer of help but alas the loco work is complete and it's gone back to it's crew.

Having done this work on 674 I really like this loco design and would very much appreciate any drawing information you wish to impart, I may build one for myself.

Your build is looking great- both of them
