The newly painted beam, raised onto a steel platform, together with an array of parallel motion components waiting to be fitted.

Clapham Beam Engine - Update


The block paving around the engine has been completed. In order to do this the crank and bedplate belonging to the Holmes triple expansion engine had to be moved out of the way. This is now back in its original position.


The beam has been painted its new colour and has been lifted onto a steel platform so that all the components of the parallel motion linkage and associated bearings can be fitted to the various pins on the beam.

This is proving to be time consuming as some of the brasses are in a poor state. Up to now a cast iron plate, onto which a bearing cotter is located, is broken and beyond repair. A  new one will have to be made. There is also a crack in one of the cast bosses on the end of one of the links. This will  also require some kind of repair.

Clapham Beam Engine - Update


Most of the parallel motion linkage has been fitted to the beam. The painting of the beam has been completed by adding the lining detail.

Clapham Beam Engine - Update


In the last few months a lot of “unseen” work has been done in preparation for lifting the beam into place, on top of the columns.



Lifting the beam, and manoeuvring it into position, ready to be lowered onto the entablature.

Once in position, the next tricky task was to align the link at the end of the beam with the Low Pressure piston rod.

Similarly, the other end of the beam had to be aligned with the crankshaft. In both cases a plumb bob and line was used. In this case the correct alignment is shown, with the plumb bob in line with the inner circle on the white card. At the same time the line had to be central with the crank pin (not shown in the photo).
