<div>I haven't any pictures of the latest arrangement but yes, I
always use a mirror.</div>

<div>The upper picture is just a test with the old tray, the top
surface of which is now covered entirely with a plate glass mirror.
The tray is adjustable for left/right cast using the rubber-footed
screws at each end and for back/front cast using the screw in the
middle. The set-square is now redundant, though I do
occasionally use it to double-check on those days when I can't believe
my eyes.</div>
<div><br></div>
<div>The sideways adjustment of the tray is for gluing on the hammers
in the bass and tenor where they are cast to right and left.</div>
