| X4117 #7 Pt.4/EAP/13-3-29 MELBOURNE. - 13th March, 1929. HY{Tom Haldenby - Plant Engineer}/Derby c.Hm.{Capt. W. Hallam - Head Repairs}/Derby c.Hs.{Lord Ernest Hives - Chair}/Derby c.WHR{Mr Wheeler}/London Chassis 33 CL - Captain Gordon Chirnside. - This Chassis has rearward extensions of Chassis Side Members to which are attached Luggage Grid and Spare Wheel Carrier. Partly owing to the extraordinarily large trunk fitted, and partly due to the roughness of Australian roads, the bolts about which the Luggage Grid hinges are already noticeably worn, after only 1,600 miles of running, - while one of the bolts which may be partially withdrawn, and which serves to locate the Grid either in the upright or horizontal position, has sheared through. I would suggest for Australian conditions that the diameters of all these bolts might well be increased, and I would also suggest that the sheet metal cover plates which enclose the channel in this neighbourhood, could very well be disposed of, as they have to be removed, involving much scratching of paint, to enable the above-mentioned parts to be removed. For rough conditions like those obtaining here, the open channel seems to me to be preferable. I would further suggest that the bolts which act as hinges for the Grid should have a much larger bearing in the Chassis member than is provided by the mere thickness of the Chassis plate itself, - that is to say, some sort of boss should be provided to give increased area of support, otherwise I confidently expect many repetitions of the trouble found with the above-mentioned Chassis.
