Brief Description: Tiedown Bars and Spacers - Left Spar
I didn't REALLY want to start deburring ribs tonight, and my #12 reamer and 3/8-20 tap showed up from McMaster-Carr (just ordered yesterday!), so I drilled and reamed the tiedown bracket and spacers to the left spar.
W-731L and W-726 spacers drilled 3/16 and reamed #12. If you look close at photo #2, you'll notice that the bolt holes through the bottom spacer (the one on the right) are very nearly centered, while the ones in the top one are ~1/4" above center.
W-731L located, clamped, and ready for backdrilling through the spar.
W-731L and W-726 spacers drilled 3/16 and reamed #12.
