Hi, I am considering getting our workshop to construct an A.I. apparatus. I already have plans for the Laidlaw and Ruttner instruments but really would like to find plans for the Swienty A.I. apparatus as it is supposed to be thbest on the market ...? Does anyone have and be prepared to part with a copy of the Swienty A.I. apparatus plans. I'd be so gratefull Philip Earle Queens University of Belfast School Biology and Biochemistry 97 Lisburn Road Belfast BT7 9BL Northern Ireland.
