The teeth in Jill's Brakewheel and Tailwheel were replaced during our restoration project.

Over the years we have received a lot of interest and help from schools.

Sondes Place School in Dorking volunteered to cut the basic shape of the new Brakewheel teeth.

 

The teeth were then seasoned before being
hand fitted by our volunteers

Our maintenance team discovered rot in one of Jill Windmill's Sweeps - originally constructed from Pitch Pine in 1982.

Following advice from millwrights and those in the timber trade, we were persuaded that Siberian Larch was of better quality than the current stocks of new Pitch Pine.


We decided to build a new Sweep using a Whip constructed from laminated larch.

The initial search of sawmills in Sussex had borne no useful results at all and so we had turned our gaze further north. Eventually we tracked down Sykes Timber, hardwood and softwood merchants based in Atherstone, Warwickshire who claimed to have a stock of top-grade slow-grown Siberian Larch and, to that end, a small group of our volunteers were dispatched to Warwickshire to check out their claims.

The team were not disappointed. They were positively overwhelmed by the quantity and quality of much of the larch.

They therefore explained to the timber merchant the reason for the potential purchase, stressing how important it was, if the team (for maintenance work) were to safely climb the sweeps once re erected on the mill, for there to be no significant knot holes or other impairments in the timber. This did not faze the timber merchant at all and he undertook to select the best timber for Jill Mill once an order was received.

The team returned to Sussex, discussed what they had seen, sized up the requirements (including spare timber for future work) and placed the order.

Within the week, the timber was dispatched by lorry to the Mill and work started immediately to cut and machine the large planks into the sections required for the rebuilding of the old sweep that needs replacing.

What is really remarkable is the quality and weight of the timber supplied. Apart from a limited amount of sap wood at the edges of the planks, all of it looks like it will be of sufficient quality to be usable for the job in hand. And the weight of the timber confirms that it really was slow-grow, and thus very close-grained which is just what was needed.

The photographs below show views of Jill Windmill before our restoration project commenced and their equivalent views in Spring 2010. It is interesting to note that most features have been retained both internally and externally, the main exceptions being the flooring in the Roundhouse and the new fantackle assembly.
