| BY {R.W. Bailey - Chief Engineer} /CS. c. Di/SS. {S. Smith} c. Ha. c. --- X4111 BY6/H. 9.5.27. In view of the difficulties we are having in brazing Staybrite steel tubes, I propose to try out another method of protecting the pipes by means of an aluminium deposit, the process being a combination of electrical deposition with a dipping in molten aluminium. Would you kindly get out a scheme for the down-take pipes, that is, the pipes between the cast exhaust pipes on the cylinders and the silencer, in which we replace brazing by welding at the extreme end of the flange and pipe, so that the welding does not come between the flange fixed to the pipe and the pipe itself. This will involve rivetting the flange on to the down-take pipe with the welding used as a joint, only at the extreme end. If there is any doubt in your mind as to exactly what I want, please come down to see me and I will demonstrate it. BY. {R.W. Bailey - Chief Engineer} | ||
