The Finished Item

Nearly there

As it was on 17/06/2006, all that remains to be done is to make the eccentric strap and sheave, parallel motion linkage and then to clean up all the rough edges, test and paint it. Then it needs a nice polished base to mount it on.

On the base

30/06/2006 – The finished engine. Mounted on a polished wood base. It worked first time and ran even better after a little fine tuning of the valve timing.

It is a fascinating engine to watch running, it was worth building just to study the action of the Watts’ parallel motion ! I will have to find a suitable place to display it now.

A lot of skills were learnt while making it including close tolerance turning, milling, accurate marking out and how to extend my patience!
