Chrome Plating Cylinders. Some time ago your department produced a rig for plating a portion of the bores of a chassis cylinder Block. We have now had sufficient experience to know that :- (a) This procedure has every chance of proving to be the answer to our Cylinder bore wear problem. (b) It is worth while therefore producing a rig, with which our complete range of rationalised blocks can be treated. Attached is a rough sketch from Mr. Aspley, combining briefly the basis requirements of the rig from his point of view. If the draughtsman you allocate for this job will co-operate with the writer and H1/EA.we can supply the remaining data to complete the job. We would point out that Anode centres need not be adjustable, as the cylinder centres are the same (radiating from the centre) for the four, six, and eight cylinder engine.
