striking rod was fitted through the windshaft and the axle for the fantail fitted in position on top of the fantail posts. At the top of the mill tower, the curb was prepared to accept the cap, and the cast iron curb track plates bolted into position. Repointing of the brickwork of the tower continued, with nearly half of it completed at the end of the second work-in. After the work-ins had ended, work continued on finishing the cap which was scheduled for lift-on in October. The weather hampered the work initially, but the application of a modern microporous paint, designed to withstand normal movement of the timber and yet remain waterproof, was completed in time for the lift-on. A mini work-in was held the weekend before the cap was lifted, with 17 people participating over the weekend. Final work was done to the cap and a new window was fitted to the stone floor of the mill. The tarpaulin was removed and the trammel dismantled. The 5-ton cap was lifted into place by a mobile crane on 24 October 1983, watched by a crowd of some 70 people. The fitting of the cap was toasted with beer from Adnams Brewery, Southwold. Restoration work in 1983 cost £1,408. Grants were received from the Association of Independent Museums, Blo' Norton Women's Institute, Ipswich Historical Transport Society, the National Association for Gifted Children, Mr D. Porter and the Society for the Protection of Ancient Buildings. Further income came from the sale of guide books and a drawing of the mill by Wilf Foreman. 1984 Four work-ins were held during 1984. The first two were by apprentices from Eastern Electricity Board. Thelnetham Windmill was chosen at the project to benefit from the Young Person's Development Project for that year. Pakenham Watermill had previously benefited from the project, and its owners, the Suffolk Preservation Trust, had suggested that Thelnetham Windmill would be a good candidate for the scheme. Two separate parties spent a week each at the mill. A mains electricity supply was provided. An underground cable was laid with assistance from British Telecom who were trialling a thrust borer which had been developed at their research facility at Martlesham Heath. The thrust borer laid of ducting through which the mains cable was pulled into position. The mill was then supplied with lights and sockets on each floor. Other work undertaken by the apprentices
