This has been a few days combined. Lately it's been around 105-115F out each day, so I'll work for a few minutes here or 

there on things. I had a bit of a hump with the nose ribs. Seems my formblock for the nose was distorted and I didn't catch it 

before I traced out and rough cut a lot of the pieces. I think they might still work fine, but I decided to set them aside for a bit 

and work on something different. I decided to tackle the two full size ribs required, so I cut them out (after ordering $400 in 

aluminum). I rough cut them out, then drilled the jig holes on them both. Then I marked and drilled the pilot holes for the 

lightening holes. One router with a circle template, three bits, and half a can of WD40 later, I had the lightening holes cut out 

and the rib ready for final trimming and flanging.

Gotcha:

• Cutting aluminum from MDF formblock with a router. The laminate bit bearing on the router heated up without lubricant and ended up scoring the template. This created a cascading issue with the templates that made them all slowly slide out of proper cut...gonna hand cut the next ones.
• May have an issue looking at this. I didn't consider the matching of the rear spar to the wing tip, so there may be a chance that I cut a lightening hole right where the rear spar connects to the wing tip. If that's the case, I may find myself making another set of wing tips (or something to fix it, which will still most likely be remaking wing tips).
