Bolts in mid spar

Drilled and reamed all the holes for the bolts on the left side. I'm not sure if the black plastic sleeve/block for the wing pins are to mounted fwd or aft on the spar.

Deburring mid spar

Finished deburring the main spar. Cleco'ed together again and drilled/reamed for the AN3 bolted rib attachment. Started drilling the steel bits as well.

Ordered some angle stock from Sandelving to make new and correct attachment angles. The ones that came with the Machined Angle Components was wrong due to error in the drawings. Can't wait for Sonex to straighten up and do what is right, have a feeling it may take ages.

Finally home again and started deburring the main spar.

The Drill Doctor was a bit disappointing. It is not usable for 40 and 30 bits. It is simply not accurate enough. All in all a waste of money, it's better to just purchase a bunch of 30 and 40 drill bits and throw them away when they are worn. For larger bits both the relative and the absolute accuracy increases so it will be OK I guess, or hope.

I also have to fix the 9.9.13 ONX-W10-03L/R revision. I will do that by making new parts from angle stock.
