started the week by preparing the MW for Berden, then working on the stuck pin by the N/S rear adjuster but twisted my back in the process so that put a halt to that for now.  Work resumed with the cab window, a tricky and time consuming job. A problem occured with the welds on the bottom channel which I think will fix adequately with strong chinese epoxy.  Otherwise the window is ready for tape removal and fitting, assuming the correct screws are available,  MW preparation for Berden Fete then ensued, so all work ceased temporarily.
