| To RHC.{R. H. Coverley - Production Engineer} from EFC. X1109 FC2/T11.12.22. X.1109 - INSULATING MATERIALS This is to confirm that you will now let us have a report on the machining tests of insulating materials; also let us have back the bits which remain. Also that you will obtain for us a sheet of ebonite about 1 ft. square, with which to make an insulating table for H.T. transformer tests. We have an ebonite rod from which four suitable legs for this table can be made. EFC. | ||
