Fritzsche" Subject: RV10-List: Elevator Push Rod Issue I have fabricated the F-1089 elevator push rod, drilled the ends, and deburred and smoothed out the inside of the tube. When I try to insert VA-111 into the push rod it does not fit. I have used a Scotch brite pad on the inside of the tube to try to expand the opening enough for VA-111 to fit, but after quite a bit of circling the pad on the inside do not seem to be making much headway. Anyone else had this problem and if so how did you solve it.

If you take your deburring tool to the inside edge of the tube and outside edge of the VA-111 to create a 'ramp' you may have better results. Just thinking out loud ....

I sanded the threaded end pieces a little and made sure the tube was really smooth on the inside. I still had to screw a grade 8 bolt in the end to extract them after drilling to debut and prime them on the inside.

I'd guess they should be within two or three thousandths. If they're close, try heating the tube with a heat gun--not too hot--and putting the plug in a freezer for a while. For a close interference fit, that usually helps a lot. --Dave On Sat, Jan 28, 2017 at 5:44 PM, David J.
