We recommend that the following system of fitting springs to cars should be adopted in future, to overcome some of the present difficulties. (1) The springs shall be ordered in batches with the poundage varying by 30 lbs. as now. Each poundage to be given a piece number. The present tolerance of 15 lbs. should be continued. (2) The springs shall be labelled with their exact poundages when stored in the production racks, as now. In addition we want to have the poundage stamped on one of the spring clips, so that it is visible when fitted, and will bring this in as soon as possible. (3) On the erection sheets works should be told the exact poundage of springs required on each chassis, and should then select a suitable spring from the rack, with a 40 lb. tolerance each way. (This is what we have now). The two piece numbers of the springs which will come within this limit may be stated, in brackets, on the erection sheet if it is thought desirable, but after a time this could be discontinued. Authority to depart from the 40 lb. tolerance should be obtained from RH{R. Hollingworth}/AFH. (4) In the event of sales altering the specification of a car after erection, the springs must be changed if the inaccuracy of poundage exceeds 65, but should it fall between the limits of 40 and 65 lbs., then the springs should not be changed but Rd, Ad, JAL and RH{R. Hollingworth}/AFH. should be informed what the springing discrepancy is. | ||
