Thanks lads,
Welcome back,
True to my word, I spent the morning working on the exhaust. I found the longitudinal centre of each and marked them with a pin scriber in two places, about central to the micro drill I was using. I then drilled two shallow holes and cleaned out the centre, leaving a roughly similar shape to the exhaust outlets. As I intended to replicate the QB set, I cut the prepared ends of each eaxhaust and glued them to the interior of the cowling. I had marked the upper and lower extremes of the cowling wall. It was then a matter of align, check, re-align until I was happy:
The lower exhaust was done the same way and then the downside to my haste became obvious. After about 30 minutes of attempting to manipulate the piece into place, I gave up and will install them from the outside later:
I worked the MG 17 troughs, both lower and upper to get a better fit for the Master Barrels MG 17 tips. Once I was happy the only thing left to do was attach the cowling:
Pretty happy with that. Thanks for looking.
