Thanks all for the reassuring input. Still waiting to hear from vans, but I think I may end up at least ordering a new rib; fortunately I never riveted it in, thinking it may need to come out. The underside of the botched hole is much cleaner and rounder, so hopefully I can clean up the existing hole enough to set a cherrymax rivet. I have also removed and plan on re-setting the other poorly set rivets nearby - fortunately I learned my lesson and managed to remove them without further damage (just drilled off the head...) I may use the cherrymax rivets here as well so as not to risk another screw up. If nothing else, it's been a good learning experience so far!

It appears that you can get to both sides, so my suggestion is to us a Hi-Lock bolt. These typically are close tolerance and have a special lock collar that breaks away upon reaching the correct torque. I would double check with Van's, but the airlines use these all the time in structural applications.

Default New rib

Personally I would go for the new rib..... whats a few dollars as against peace of mind?

There is though another possible solution, rivet in a 90 degree gusset plate rivitted to the existing rib and the spar.

Best of luck.

Well the gods at Vans have spoken, and suggested a simple #8 screw and 'move on with the build'. But I do plan on using a new rib, for my own piece of mind. Practicing on scrap, and using my VS build as a cool-down period before I go back at the HS.

Follow Van's advice. Don't be afraid to put a new flange on the rib. Simply cut off the flange and add a new one.
As mentioned, never drill through a rivet. View the EAA video on rivet removal.
As a side note, insure your work is held firmly while riveting. Many errors in riveting are caused by a poorly supported part.

For what it is worth, there are no hi-loks, cherry max, oops rivets, bolts, or other hardware in my entire airframe used to fix a mistake. Almost without exception you can repair any damaged part and put it back with the same construction and type of fastener. I made plenty of mistakes but chose to repair the parts as new rather than use other types of fasteners. Personal choice.

Get your hands on AC-43-13b. It is downloadable as PDF's or you can still order a copy. It covers many different recommended practices for repairs, acceptable standards, etc...

Keep moving forward. You are doing fine.
