The right hand wing panel is almost finished. Now that I think all of the dimpling has been done, I came up with a much better way of doing it. After losing my small dimple die on the floor of the shed for the third time I spent about an hour or so fiddling around with a bolt and nut on the lathe and turned up a replacement nib for the hand held rivet gun. It is so much easier, no fiddling around, if I break the nail, nothing goes flying and it's a piece of cake to continue on with the job.
The dark screw with the point replaces the silver nib in the middle on the rivet gun.
Which you can see here, unfortunately it will probably not ever get used again!
