Brief Description:  Spar - Rivet Shaver

While working on the leading edge I noticed proud rivets on the platenuts that will hold the tanks. I bought this rivet shaver and did a lot of practice with it on various drills, speeds, and techniques. The results are good. This is the rivet shaver bit from Avery, mounted in the larger c'sink cage with the nylon no-scratch foot. The lessons learned are this bit needs to spin fast like 8,000 rpm and a die grinder will spin up to 10,000. I used Boelube on my c'sink cage because it is only rated to 3,000 rpm. But it held up fine. My 3,000 rpm drill was not fast enough evidenced by binding of the bit causing forces on cage to move too much. This is a very sensitive tool and you can't rush its shaving action, but it does go fast. From practicing I got it set so shaver bit is flush with bottom of foot. The technique is important and requires practice. I hold it flush over a proud rivet with back of hand against the material. Spin up to full speed and slowly push the bit onto the rivet. You'll feel when it starts to shave. Let it shave and apply more pressure as you feel it working. The cage will want to move, walk or vibrate but you can easily hold it. Don't push to hard or fast. Let it shave. It only takes a few seconds. You'll feel when bit is no longer shaving the rivet and you can move it in more or tap it a little and move the cage around with 1/16 inch to make sure you covered the whole rivet head. Result is the head gets flush and there is no damage not even a mark on the surrounding area. I have not tried it yet on a skin.
