| Today I was on my own, so I looked at the nav / strobe lights with the wing tips | 
|
| The base of the Whelen lights require something to screw into. One option is to put the nutplates directly in the fibre glass. However we decided a 'AL washer' would be a better solution. I knocked up a CAD diagram of what was needed and started with a couple of pieces of 032 AL sheet | 
|
| The only method I had to create 1 5/16" was with a fly cutter. Worked OK on the AL, but not good for the fibre glass tips. | 
|
| The rest of the shaping was OK. | 
|
| I gave in and went a purchased a new hole saw (1 3/8") which made the right size main hole in the fibreglass tips. | 
|
| To finish the shaping I used a rotary burr - this was all a bit new as I haven't worked on glass components before. It was actually easier than I thought. | 
|
| Then the problems occurred - the plate wasn't really big enough for the nutplate mounts. I could of used one legged nutplates (but didn't have any) and decided the easier option was just to re-make the plate bigger. | 
|
| All finished with nutplates installed ready to go. I also started looking at the tip plexi-glass covers which is tomorrows activity I think. |
