I screwed up on the last ones that I cut. The holes for the bolts were too big. Not sure how I managed to draw them like that but I did. Its easy enough to make some new ones.
Aluminum parts in the acid etch bubbling away. I always hated the smell of this stuff 😦
Parts in alodine doing its thing.
Here is a shot of riveting the anchor nuts.
You can see one of the 1/4 inch holes for the dowels is right where the inserts go. My cores are older ones and I know this has been corrected by Eureka CNC.
Here is what my finished recess looks like. The cores are so easy to cut that it doesn’t take much to make the relief for the anchor nuts. I just used a small screwdriver and dug them out.
All ready to start laying up the shear web.
All the layers are on.
Followed by some peel ply.
After it was cured I installed the lift tabs and torqued them to the plans. I also made sure they were pointing in the right direction 🙂
Dowels are epoxied in and ready to bond the leading edge on.
The leading edge is bonded and clamped down.
