yes Ray, try not to touch the web while drilling out the solid rivets. I use a nice tool I´ve bought a Aircraft Tools to do the job.
Ray we never removed the spar to do the upgrades we kept the leading edge attached at the bottom but you can remove it if you need to but keep the rear bottom skin and ribbs attached.. Call me if you need any other help
Brilliant, not only does it help but what a great motivator! Thanks Phill
I think Ray is talking about the spar carry-through stucture, the big heavy thing under your knees when sitting in the airplane. I think most of the advice given is referencing the spar in the wing, not the carry-through spar in the fuselage.
I have not built my fuselage yet, so I will be incorporating the upgrade as part of the build. The one piece of advice I remember from the discussions at the beginning of the upgrade era is that several people recommended propping up the fuselage at several places before removeing all that stuff from the middle. Some folks had trouble with the fuselage distorting without all the structure in place.
There were several good discussion threads about doing that work here in this forum, you should be able to find them with some digging in the archives.
Took your advice and added some support to the fuselage after removing the spar.
