A start on the re-inforced traverser was made this evening. I bought soft steel bar and cut it into ten 18cm lengths. I have placed these either side of five of the nine rails, trapping the appropriate roller bearings in place. Nothing has been fixed yet. The spare roller bearings will be redundant but cannot be removed easily so will be parked out of the way (with blutac?) Tomorrow I will drill holes in the bars and the Tufnol deck and bolt the bars in place. 5 x 3 ball bearings should work well to evenly spread the load while the bars will maintain position without yaw.
