Model Enthusiasts for Mamod
"When I set up Model Enthusiasts in 2004 the idea was to find out
what people with a Mamod engine needed to get the
engine running as it should."
That's still true today

 10  ALUMINIUM RIVETS FOR MAMOD STEAM ENGINES 1/8th   

For your Mamod engine renovation project.

Using top quality rivets is really important if you don't want to do the same job on your Mamod steam engine in the future. That is why we only supply top quality rivets.

They are aluminium with a steel mandrel. These are 3.2mm dia. and 8mm long (1/8th inch type). 

You will use these when you attach the Engine Bracket which holds the Crankshaft/ Flywheel, to the Firebox. They may be useful when attaching the Smoke Box IF those holes have been over-sized.

So basically, you will need at least two of these rivets for your Mamod engine renovation. But it is always helpful to have more just in case.
