We have fitted up the cycle type front wings on the temporary mild steel stays, and it is obvious that these stays will be very much too flexible. The fact that the final ones would have been in spring steel would not have increased the rigidity since the modulus of elesticity for all steel is approximately the same. We are making at Messrs. Park Ward & Co.'s Works some rigid forgings to bolt on to the stub-axle, extending upwards about 8" above the brake-drums. On to these we are proposing to bolt on the spring steel stays. By so doing we still maintain a portion of the wing support which is capable of being flexed, and yet the degree of flexibility is reduced to within reasonable limits. When the car comes to Derby the Design Office will be able to see the hard forgings that we have produced, and will no doubt wish to design suitable drop-forgings for use on subsequent occasions.
