During 1968, Peter constructed and designed all the apparatus to set up the silk screen-printing room and gold plating section and made the tanks. A new cutting machine was purchased and one of the latest drilling machines installed on hire purchase.

During 1969 the more advanced type of boards were introduced using fibreglass and a printed circuit on each side, connections were made by through hole electro-plating, with which even the largest firms were having difficulty. Peter spent several weeks experimenting with different methods and chemicals until he had mastered the technique. Then came a long postal strike and four workers had to be laid off.

A bank loan was arranged to tide things over and a secondary company was opened selling motor ignition units by mail order to help cash flow. However in 1972 came the miners strike. All firms were limited to a three-day week to conserve electricity, and a customer went into receivership owing over a thousand pounds for boards.

Adjoining, vacant premises were rented. A new type of Hi- Fi Speaker was designed for possible future production and articles for technical magazines raised a little extra cash, but over two million were unemployed and orders were scarce. David and Roger helped during school holidays and weekends.
