Once the C-611 blocks were drilled I slipped them back onto the ends of the WD-617 latch weldment and then bolted the assembly to the F-705 bulkhead. The final task for today was to rivet the VS-411PP brackets to the F-705 bulkhead. I was able to use the pneumatic squeezer to set all of these rivets. I'm not sure why I didn't do this earlier.
