We are trying various ways of strengthening this frame, and the next thing we wish to try is thicker plates in the centre of the cross, top and bottom. The present plates are .170" thick and we wish to double that thickness and try plates .325" thick. As it will take some time to make these we hope it may be possible to start on them while we are carrying out further tests on the frame as it is. Rm{William Robotham - Chief Engineer}/C1m. | ||
