My F623L & R ribs have a joggle on the outside vertical flange where it meets the F705 bulkhead. The joggle seems intended to allow a rivet to tie the side skin, f705 bulkhead & the outside flange of the F623 together. However, view C-C (side view of this point) seems to show the F623 rib being cut off just short of the F705 bulkhead flange. If I cut nothing, I'll have a joggle in the bottom skin (obviously wrong). If I cut as shown in view C-C, I'm cutting off a joggle in the flange that Van's went to the trouble of adding to the rib. My 1st thought is to cut the inside flange & horizontal surface of the F623 & leave the joggled tab for riveting to F705. Should I do something different? Bonus question1: The instructions say to cut a 1 1/2" hole in one of the baggage ribs if you intend to add a step. Is there any harm in cutting this hole if no step is planned? (grams add up to ounces add up to pounds....) Bonus question2: Any harm in enlarging the back tooling holes in the seat ribs to 5/8", like the front ones? (possible future wiring path, if needed) Thanks, Charlie ________________________________ Message 2 _____________________________________ Time: 03:45:14 PM PST US From: "tadsargent" Subject: Re: RV7-List: fuselage center, f-623 rib question --> RV7-List message posted by: "tadsargent" Charlie I can answer Bonus question 1. No step installed, no holed be drilled. Weight is not that big of a deal if you install a 360CID Lycoming. Bonus question 2. Yes enlarge the holes. It is amazing how much wiring space is needed. Add this up. Manual trim cable, Tail strobe and Nav light. Then if you put the ELT or Altitude hold. As for the flange recheck the instruction or call Van's for help before you cut anything off.
