Merlin Spares

Post by Gareth McGrillen » Mon Jan 14, 2019 5:15 pm

Hello,
I am new to G scale live steam modelling and have recently inherited my Grandfathers Merlin gas locomotive. I originally had to fix the servo control circuit and in doing so I snapped a bolt on the gas/ignition system.

Does anyone know where I can buy replacement parts fro Merlin locomotives.

To those more familiar with these systems it is hollow - I assume to allow gas to flow through it if that helps.

Thank you
Gareth

Gareth,
Your description sounds like a "banjo" bolt.
Merlin are long defunct, so parts are unavailable.
A model tool/screw supplier may be able to help, but you would need to know the size & thread pitch etc.

Alternatively a Merlin owner may have some better suggestions.
Must say, there have been no replies yet!

A model engineer, such as Tony at Rhos Helyg may be able to make/adapt something to fit.

Good luck!

Thanks for the recommendation Rob, but unfortunately I cannot help.

My suggestion would be to contact Simon Whenmouth at http://www.anythingnarrowgauge.co.uk/

As Tony said try Simon.
However, banjo bolts are used on a lot of other things, fuel systems on cars for one. If you have a local Diesel injection specialist they may be able to help If you take along the parts.

Can you post a picture of the bits and where it screws in to?
If at first you don't succeed, use a bigger hammer!

Here are three images depicting the broken part and the cab showing where it went.

Hi Gareth
The Merlin banjo thread size is M5 x 0.8mm. They also used PTFE washers to seal the joint.
Hope this helps.
Regards
Ian

Thanks for the recommendation. I emailed Simon and we've sorted a new bolt out. Loco still doesn't run but we're getting there

Glad to hear things are moving on a bit.
It's all part of the fun of steam engines.
