Fabricated F729C. When I started making F729B and F728B, both of them are made out of AA6-063x3/4x3/4 aluminum angle, I found only about 19" angle left, not enough to make these two parts. Don't know why. I double checked the invoice, there is only AA6-063x3/4x3/4x6' angle, I have used it for many parts. Anyway, I might need to order more from Vans. But I will check Home Depot first.
Short of the aluminum angle, I started F707 bulkead. Deburred one piece tonight.
