Workd on the fitting of the oil cooler intake in readiness for getting this set ahead of any planned engine run.
The aim, I believe, is to get it stuck well and truly into the airflow and get a funnel effect going so that it has a form of ram air cooling.
This fitting will let me mount the cooler upright .. put the oil pipes down vertically into the top (so you dont get air locks) and still keep it reasonably accessible
Update 20 Feb –
Now etched and brackets trimmed a little. This will be bolted on vs riveted on in case I need to remove the entire arrangement.
