PHANTOM 11 - CAMSHAFT AND TAPPET. ----------------------- I have telephoned through to Firths asking them to let us have quickly 42/ft. of 1" bar and six lengths for camshafts 39 3/4" long x 2.1/16" diameter. These parts are required in 2% (two per cent) case hardening nickel steel, with the object of endeavouring to get a harder surface on both tappet and cam. BY.{R.W. Bailey - Chief Engineer} | ||
