More Steam Mule Progress

More Steam Mule Progress

6th January 2010

Whilst precious little else is happening on account of the relentless cold and snowy weather, I thought this afternoon’s latest progress on the steam mule might be of interest…

Below: John Moore has completed the basic water tank – seen here with the lid on the right. This will be slung underneath the chassis and is still awaiting ‘fake’ rivets to be fitted.

Below: The chassis is also being assembled and is seen here after welding and bolting. The snowplough is also now complete and ready for collection and final weatherproofing treatment. Ironically the snow is rather hampering this!

Below: Meanwhile! David Young is working on the crankshaft. This view shows the completed big end on the connecting rod, complete with oil pot.

Below: The connecting rod laid over the circular cranks. These will be mounted on a single crank axle, then a second axle will be fitted to create the crank throw. The centre of the axle is then cut away to leave the connecting rod free to swing. I’ll try and post pictures of the process to explain it rather better!

Below: The assembled cylinder, slide bar, crosshead and piston. Note also the cross shaft for the reversing gear protruding from the baseplate sides.
