Brief Description: Finished roll bar and ready for primer
Spent the day enlarging all holes to #30 with a #30 reamer. Nice. Countersank the forward halves including the 16 holes that attach to the F-631E connector plate for AD-4 flush rivets. Then countersank the rear halves with the 120 degree countersink for the CS-4 pull rivets. The rear F-631E onnector plate gets standard 470 rivets. I fitted all the attach angles to the rear half after positioning the F-632A top brace. The RV7 plans calls for the longer top angle to be 88 degrees, but it doesn't say that on the RV6 plans. I did it anyways. The top of the attached F-632A brace is supposed to be 1/4 inch below the top of the roll bar so thats where I marked it before drilling the angle to the F-631. I wont drill the F-632A until I position everything on the airplane. By the way, I clamped the F-631C 3/16 roll bar attach angles to the roll bar and propped it in place in the fuselage. I am happy to report that my 2nd roll bar is exactly the width it is suppoed to be, with maybe 1/32 too wide but after riveting I expect to lose a little width dimension like I did before. Either way, It will work perfectly now. Hoorayy!!.
All holes enlarged and countersank where called for.
Ready for the F-632A top channel.
100 degree countersink on front halves. 120 degree on rear halves.
