G'Day all,
I am about to attach the Vertical Stab to my RV-8 QB fuse however I have found something that I think may be a mistake from the QB factory. I have emailed Vans and I am waiting for a reply however in the meantime I thought I would get your thoughts.
The instructions on page 8-55 clearly state that you drill the 3 quarter inch bolt holes through the vertical stabilser rear spar, the F-812-1 Bulkhead assembly and the WD-409 Tailspring mount only once the vertical stabiliser has been attached to the fuselage using the #30 locating hole in the VS rear spar, clamped the front spar and the VS measured for equal distance to the horizontal stabilser ends. It says to drill the bolt holes first in #30 then in 1/4 inch through the vertical stabiliser rear spar, the F-812-1 Bulkhead assembly and the WD409 tailspring mount from the outside in.
Here is my problem: My F-812-1 Bulkhead assembly and WD409 tailspring mount have already been drilled 1/4 inch by the quickbuild factory (See attached photo). I am unable to get a drill into the space to drill from the inside out of the fuselage to match drill these holes into the Vertical Stabiliser as the Vertical Stabiliser will be in the way and the space is too small for anything I have to drill with. Can anyone please advise me if this is/was the same with their QB fuselage?
Does anyone have any suggestions regarding drilling the holes to match, either some sort of drill to get into the fuse so I can match drill using the existing holes or some ingenious way of match drilling the holes from the outside in. I have ruled out marking the holes with a marker and drilling the VS rear spar off the fuse as I don't think it is an accurate enough method for this particular application.
Any suggestions would be greatly appreciated! I will post the response from Vans when I get it.
Regards,
Andy Griffin
