WOTSIT NO.3

This very "Mills" looking engine came to us in an estate purchase some years ago and is missing some rather important bits. While it does have a certain "MILLS" appearance we could find no trace of it in our rather detailed archive.

Having spent enough time in the back burner project box, time to get things moving on this little engine. Based on the bore we are going to work with the theory that this engine was originally around the 1.3cc displacement and therefore will go ahead and make a suitable crankshaft.

First step, dismantle and assess the engine for the repairs needed to bring him back to life.

Well apart from the obvious need for a crankshaft and front end it looks like this old boy will also need a new rod and a re bore, and a jolly good bath.....

Having got ourselves all organised we went ahead and started on the new crankshaft.

Here it is with the big end journal  machined in ready for the counterbalance and lubrication drillings to be done.

And here we have the finished crankshaft ready for fitting into the crankcase.

Next step is to remachine the crankcase cylinder hole as the original cylinder liner is very loose in the case and there is no sealing between them.
