Panel Drilling - Part 7

This blog covers the final drilling for the front mounted instruments and trail assembly with the panel now ready for painting - black.

Overview

Tucano Panel

As part of the styling it has been decided to front mount a number of the instruments. The airspeed was flat backed and just screwed on but the altimeter and ROC required a larger hole at the 7 o'clock position. 

This was achieved using a step drill plus a block of wood to hold the drill in alignment after it cleared away all the aluminium. A small amount of dressing was still required to achieve a neat fit.

Drilling to fit the altimeter

Fixing an error - Two pieces of aluminum sheet were covered with packing tape.
With one held to the rear with the spring clamp, Loctite aluminium epoxy is spooned 
into the cavity, top strip fitted, then all the excess extrudes out
the opening with little dressing required once cured
