I tried your solution to trimming down proud flush rivets; worked like a charm.
I had a roll of metal tape with a peel off backing (I think it is a tape that is used on HVAC ductwork joints, and I had a 2" round arbor burnishing kit with some assorted scotch brite pads from HFreight. I used a right angle pneumatic die grinder first with a red abrasive disc and then finished with a blue fine. Took a couple of minutes to do four rivets in a row on the bottom side of the left elevator at the first inboard rib at the trim activator. No issues and easy. Thanks for the good description.

I bought an Avery rivet shaver and was disappointed at first when trying to shave down a few rivets on my canopy fairing. After going back to it several times I started getting the hang of it and actually it works pretty good now. The cage turns a little and makes a little mark but soon all of the skin will be etched for painting and It will blend in fine.

Reverse thread on HD cage
For anyone purchasing the Zephyr heavy duty countersink cage from Brown tool, note that the locking ring and the adjustment body are reverse threaded compared to regular countersink tools. Traps for young players I guess. I think I may well use Dale's tape method anyway and report back.

Rivet Shaver Bit from Avery.
YES, I bought the rivet shaver bit and it works great. It takes a little finesse. Be careful with it. You can see what I did here. http://www.mykitlog.com/users/displa...=66691&row=188

The area is along the forward part of the leading edge of the tank where the skins curves a lot. I tried resqueezing the rivets to try and flatten out the flush rivet heads but to no avail.
I'm sure they are quite structurely sound, but wondering what to do about the fit and finish here on these rivets. Can I attempt a lit bit of pneumatic riveting to try and set these a little flatter or is it too late now? Perhaps the rivet has hardened making it much harder to change their shape.
Avery Tools sells a rivet shaver bit that can be set in a C/S cage. The shaver bit is 7/16ths across though, making it kind of big for my needs.
Does anyone have any experience with this tool or any other recommendations for how to handle my problem?

Hi Guys,
I seem to be unable to to find the stainless steel tape (heaps of aluminium but not stainless steel) on either the JC Whitney or MSCDirect sites. The only stainless steel tape I can find is a role on Amazon, but it is 0.0038", not the 0.002" recommended by Dale. Has anyone been able to find 0.002" thick tape online, or is the Amazon tape OK for this application even though it's a little thicker?

Cheers,

The thicker tape would work. You're using the tape as a sacrificial layer. Keeps sanding the area until the tape wears through. Once you start removing tape around the rivet, go a little bit easier/slower and you should notice when the steel is gone and you are into the adhesive layer. At the first sign of this, you stop.

Cool. Thanks Larry. I've gone ahead and ordered the stuff from Amazon. This should be an interesting grinding experience.
Cheers.
Tom.
