### Instructions and Help about Who Form 8453 S Index

Welcome back to Ox Tools. I'm Tom. Today, we have an interesting problem to discuss. One of our viewers, Eric, asked me a couple of questions about indexing a square on the end of something, like a Chuck key. So, I started thinking about different methods to achieve accurate indexing, especially for someone with minimal tooling and equipment. Eric is just starting out and doesn't have a lot of tools or money to spend. He only has a mill, some one two three blocks, and a few cutters. Despite the limited tooling, there are still ways to achieve accurate indexing. However, it does get trickier with minimal tooling. Imagine being on a desert island with just a milling machine, a vise, and a couple of parallels. How would you achieve accurate indexing under such constraints? I fiddled around with some possibilities and thought it would make an interesting video. So, let's get started. Our test victim is a piece of half-inch diameter cold rolled steel rod. We'll be putting a square on one end. One possible method to achieve this is by clamping the rod to something else that is square, like a square block. Another method could involve attaching something temporarily to the end of the rod that can be used as an index. However, for the purpose of this demonstration, we'll be using common tooling. Eric mentioned having one two three blocks and access to parallels, so we'll make use of those. I thought it would be interesting to clamp something to the rod that can serve as a reference for 90 degrees. This could be a parallel or a lathe tool bit. By clamping it in place, we can easily achieve a 90 degree index. Now that we have a general idea of what we're going to do, let's set up and get...
