 or laminated stocks . Good quality pitch pine was not obtainable in the lengths required . Douglas fir was obtainable in such lengths but was discounted on strength and durability grounds . A Douglas fir stock on a nearby mill had rotted after only seven years . Thus it was decided that laminated stocks would be made .   The 52 feet ( 15 @.@ 85 m ) long stocks were made from Douglas fir . All timber had been pressure treated with preservative and well seasoned . It was estimated that a laminated stock would be up to 20 % stronger than a similar stock of solid timber . The timber used was 1 1 ⁄ 2 inches ( 38 mm ) thick and nine laminations were required at the centre , where the stock passes through the poll end of the windshaft . Careful attention was paid to where individual joints occurred between different pieces of timber . Both stocks were made during the work @-@ in , with one of them being trimmed and finished ready for use . The stocks were the first laminated stocks made by amateurs .   The four sails were made . The originals being slightly different pairs . Those on the inner stock having bays of 3 feet ( 910 mm ) pitch and those on the outer stock having bays of 3 feet 2 inches ( 970 mm ) pitch . It was decided that the new sails would be identical , at the larger pitch . Four 27 feet ( 8 @.@ 23 m ) long whips were cut from a baulk of pitch pine obtained from a demolished maltings at Bury St Edmunds . The whips are 6 inches ( 150 mm ) square at their inner end . Sail bars and uplongs were made from modern pitch pine , selected for quality . The mortices for the sail bars were cut . That at the heel of the sail being at 27 ° and that at the tip being 15 ° , decreasing by 1 ½ ° at each sail bar . Three of the four sails had been completed at the end of the work in .   The fantail and associated gearing was fitted to the mill . At the end of the second work @-@ in , the cap could be turned by means of the hand crank . The fantail itself , with the blades painted red , white and blue was installed shortly afterwards . The clasp arm brake wheel was assembled around the windshaft . It was found that the wallower was eccentric on the upright shaft by ½ inch ( 13 mm ) . When this was corrected the brake wheel was within 1 / 16 th of an inch ( less than 1 mm ) of true . The clamps for the stocks were sawn from a baulk of pitch pine ready for completion later in the year . Other work included a new frame for one of the ground floor doors , cleaning and painting ironwork and further repointing on the brickwork . The four sails were fitted to the mill with the aid of a mobile crane at the end of the second work @-@ in . The stock , with one sail attached was carefully inserted through the poll end of the windshaft and when wedged in position and the clamps had been attached the second sail was fitted to the stock . The process was repeated for the second pair of sails . The mill turned by wind again on the last day of the second work @-@ in .   Work later in the year included the finishing of the fourth sail , balancing the fantail and sorting out teething troubles with the fantail gearing . The brake and brake lever were made and installed and shutter cranks for the sails were cast .   Restoration work in 1984 cost £ 2 @,@ 918 . Grants received were £ 1 @,@ 209 from English Heritage , £ 500 from St Edmundsbury Borough Council , Other donations amounted to £ 52 . Income from open days at the mill came to £ 151 . A boost to the funds was £ 2 @,@ 000 from Hervey Benham . This money had been allocated to allow the moving of a derelict post mill buck to Thelnetham . In the end , the removal was not proceeded with , and Mr Benham allowed the donation to remain with the Thelnetham Mill Preservation Trust . The project received further support in local media , including the East Anglian Daily Times , one of the work @-@ ins being featured on Anglia Television 's About Anglia programme .   = = = 1985 - 87 = = =   Work planned for 1985 included the replacement of the dust floor window and completion of the stocks and sails . The external walls of the mill were tarred and internal walls plastered . Two work @-@ ins were held , from 20 July to 28 July and 17 August to 26 August . Further work over the next two years saw the restoration completed in 1987 .   = = Restoration team = =   The restoration of Thelnetham Windmill was made possible by the efforts of 135 individuals and 61 organisations . This was achieved by the donation of labour , plant , materials or grants of money
