Bailey - Chief Engineer} ORIGINAL REC'D AUG 27 X4225 RE "GOSHAWK(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine)) II" CYLINDER STUD TUBES. Referring to the method of opening out the tubes in the "Goshawk(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine)) II" cylinder block, it was suggested down here a little while ago that a small cage of rollers could be dropped into the end of the tube when it was in position in the cylinder block, and then a long tapered rod could be run through centrally by means of a drilling machine and so expanding the end of the tube by means of the rollers, leaving it in a set-up condition in the hole. Mr. Royce thinks this idea worth trying. E. {Mr Elliott - Chief Engineer} | ||
