Building my flightcase - Part 2

Today I did the metalwork of the bottom part of the case. Four threeway mitre joints on the corner profiles and four regular mitre joints on the rims. I planned to do threeway mitres on the rims as well, but the rim profile is only 20mm wide, whereas the corner profile is 22mm. That means that the angle would not be 45° and would therefore be a bit tricky to get right.

I'll do the lid next weekend.
