This is a really simple tool to create rivets onto your scale models. I think the pic is quite explaining, you’ve just to make a V cut on the border of a various size copper tubes, mount them on a handler, use a styrene strip with the same size hole as a guide, and gently turn the tool many times, clockwise and anti-clockwise.
You can clean the obtained rivet with a fine grain sandpaper or with a drop of thin glue, like Tamiya Extra Thin Glue.
Have a good time modeling!
