Just about finished assembly of the HS - 3.5 hours

I started off the evening working on the left side HS. I fitted the new HS00005 and 000006 ribs to the assembly. I checked, checked and re-checked the fit before i started to drill. My first set of holes were in the aft flange of HS00005.  Then in the aft flange of HS00006 through to HS00005. I was very pleased with how everything lined up. 

I then noticed that my edge distance on my top hole of HS0005/00006 was just a bit high about 1/16". I was a tad bit concerned about edge distance. The holes line up perfectly....although getting these holes drilled perfect is extremely difficult. its hard to get the appropriate dimensions in there with the skin on and all the surrounding clecos. At worst I have an edge distance of 0.209" (0.155" from the edge of hole to edge of rib) on the top most #30 hole in the forward flange of HS00005 where it attaches to HS-710. I see the listed edge distance minimum is 0.219, so I am just ever so slightly over the limit.  I will email vans and double check that I am ok.

(Darn...what its a tough spot to drill and there is little room for error!!)

UPDATE: See October 22, 2014.



I finished up by cleco'ing the HS assembly together. Whew....Just about done. All I need to do is drill the holes outboard of the bend line in the front spar.

I took the skins off the HS and started to double check how straight everything is. I will save the drilling for another day as it is getting late.
