mlapaglia Report post Posted April 20, 2013 Simple question. What is the hole on the side of the Tandy and Osborne copper rivet setting tool? The one on the end is to set the burr and the dome is to round out the rivet shaft top. On the Tandy the whole on the side does not go through to the other side. I dont know about the Osborne. Anyone know what its for? Michael Quote Share this post Link to post Share on other sites
Bryan M Report post Posted April 20, 2013 Yes, thats so you can't pull a vacuum and get the post stuck in the set. Blacksmiths also use holes in a tool like that, its called a monkey tool. Those are used to square up tennons on various things that have tennons. Rails, grates, gates ect. The same principle applies. The fit should be so tight that you get no deformation of the burr as you set it. Thats tight enough to cause a problem with vacuum. Quote Share this post Link to post Share on other sites
