1. Closed 1964. Last operating Welsh fulling mill. No remaining machinery. Used to be a pair of 2 wooden mallets, driven by tappet wheel (56 in. diameter) for fulling cloth. Builder, Newtown Foundry, Millwright - Samuel Owens 1859. Wheel, 11 wooden spokes, iron rim, 20 ft. diameter, about 30 buckets. (Martin Ashby 1979).
2. FACTORY ISAF, [ABERCEGIR] (SH 8010 0195)
Remains of a large woollen factory, part demolished, part remaining as store. Overhead shafting survives.
The [north] end nearest the present house retains the very large backshot water-wheel: cast-iron rim (marked OWEN NEWTOWN) with ten wooden spokes. Gear-ring and high-speed cog to shafting. Gear-train to tappet-shafts of fulling-stocks in basement; free-standing late 19th C cast-iron stocks (of 'Holbeck' pattern cf Moelwyn Mill, Tanysgrisiau).
The wheel was operational until c.1962. There is a Pelton wheel in an adjacent building for generating electricity. It is probably the 'Abercegyr Mill' of which a plan is reproduced in Jenkins, The Welsh Woollen Industry, p.306. This mill was reputed to have been operational from 1804 to 1964 (ibid.164).
(Source: A.J.Parkinson field notes, 19 November 1992 (7 June 1994)).
Believed to be one of only two complete fulling mills in Wales, the other being Moelwyn Mill, Blaenau Ffestinog (nprn 40924)
