It was some time sgo that we made the cooker fiddles and we always knew that fitting would be another 5 minute boat job, or about 4 boat hours all going well. Drilling the top mounting holes in sheet steel without being able to run any cooling fluid was a nightmare as the cooker cradle heat hardened and all of our HSS CNC bits found it hard going. Then the need to drill at a lower level necessitated the removal of the cooker hobs, microwave and gimballed cradle. We are now trialling cobalt tip drills.
The final fit has worked out well and deals withe issue of different heights between the gas cooker and the ceramic hobs. Perhaps it would have been more practical to keep the pan retainers straight to maximise flexibility but aesthetically that would have been bland and would not have centred on the offset ceramic hobs.
