I'm revamping some original McLellan saddles for reinactment and the rivets are a bitch to get my anvil under to get them in the original holes. I'm making due, but wondering if there is a hand tool that would set the burr and squeeze it down, and possibly round it? It's a royal pain trying to manipulate the saddle and hold it in the correct position to barely get the tip of the anvil under the head. (I'm using round and flat head brass rivets with burrs, if that makes any difference.) As we will most likely be making some modern versions in the future, I would like to have a tool to make this process quicker and easier. I've looked for tools online, but all I'm finding are the typical hand setters. Thanks in advance!
