Hi,
New RV builder here so please bare with me. I have started with the VS for me RV7 as it seems to be the simplest empennage part to put together but I have already hit somewhat of a wall! I have countersinked the doubler so that it could match the dimpled rear spar. The problem I have is that the countersink look pretty deep! I know that it is common to oversink but I tried different depth on a practice piece and I went with the depth that gave me the best fit (spar flush with doubler) as oppose to just countersinking just below what would be required for a flush rivet.
Does anybody have a trick to gauge the proper depth of the countersink when matching a dimpled part? I have contacted Vans about this and I hope not to have to do it over again. But I will if I have to...of course.
Thanks.
