Thanks stealth.
I'll give both a try.

G'Day all.
I have a Cessna 310L cockpit which I will be converting to a simulator.
I wish for it to stay as authentic as possible, including method of
construction and cosmetics.
As such I have to repair/replace and modify some aluminium panels.
My question:
What is the best way to remove solid rivets?


you need to drill out the rivet without enlarging or "figure 8'ing"
the underlying hole. that is the basic principle.
whatever way works for you without damaging the underlying sheet is
ok.

ordinary drills are often not stiff enough to stay in position.
double ended jobber drills that have shorter flutes and are thus
stiffer can be useful.

you should also search out a drill called variously a centre drill or
a slocumbe drill. machinists shops carry them. they have a stepped end
and are comparitively very stiff. a number 2 or number 3 would be
useful.

my old LAME swore by a blunt quarter inch wood chisel, it had just the
right end sharpness and could be used to pling off the head sideways
with a tap from a hammer. the rivet body was then tapped out of the
hole with a pin punch.

if you can work precisely and develop a gentle touch you should have
no problems.
