TC visit from Jamie Ball. Jamie helped us fit the roll bar, as it was not keen to slide into place. It just needed a firmer hand on the top pof the bar to smack it down ontot he support brackets. Jamie suggested chamfering the edges of the brackets to assist in final fitting. Match drilled roll bar, removed and deburred. Prepared, primed and fitted baggage bulkheads. Jamie showed me how a copper cleco can hold a nutplate in place throught he screw hole. Why have I never thought of that??
