Sully,



I don't really have any great tips. Mine didn't turn out perfect.  I will

agree that the instructions are lacking here.  I assume that the tooling

holes are for trimming to.  I trimmed a little off both ends, to

approximately where the tooling holes are because I've never seen tooling

holes in the finished product.  Then I just used the portion of the

stiffener that fit the curves the best. I ended up with them being a little

shorter than some. Mine come about 3/16" short of the longeron and don't hit

the very last hole at the upper rear side.  I don't think it matters though.

I seem to recall some RV6s don't even have them installed at all.



One picture of mine is all I can find right now, included.

Sully,



I did mine like Bevan. If you're going to have a

baggage cover leave a 1/4" off the longeron. Start off

cutting out flush with the tooling holes. I called

Van's about the top tying in with the top at the

bulkhead. They stated it was not necessary.



Good Luck

I think I remember just having to fight it!  At least knowing there is not

an easier way might help you just go ahead and get through it.

Guys,

Thanks for the replies, Bevan yours look a lot better than mine, I was trying to make them pick up the uppermost hole common to the bulkhead flange, I think I'll pitch that idea and let them stop past the last skin hole.

Yep, twist the crap out of it and do not trim off much material, angle the

bottom to fit snug on top of the longeron and don't obsess about it because

it is just a stiffener.  The rib also requires some serious fluting.  Go

slow a little at a time and yeah, I had to buy one extra to get it right.

Good Luck CJ

Here's some of the best advice I ever read.  Unfortunately, I didn't read it until I messed up my first F-6111. Works like a  charm! I found it on VAF.

  

 First don't cut them shorter! draw a center line  down the flange, then trim the bottom edge to fit the longeron, the top  flange needs a long taper trimed to fit the bulkhead. Hold the rib tight  to the longeron set the line in the holes and start drilling and clecoing from  the bottom to the top. it looks like no way but it will go right in and is realy  easy. no fluting needed just a slight twist to get the top to fit the bulkhead  tight

good luck

Frank
