Hey guys, welcome back to Metal Tips and Tricks. My name is Dale. Today I want to show you how to put square stock into your lathe using 4 jaw chuck. So you think putting a square item into the lathe is really easy. Well it is and it isn't. You have to have a 4 jaw chuck of course. The challenge here is this stock is actually not square, it is rectangular. But the same principle as bulls apply and how I am going to show you how to do this. We are going to set up a gauge here. We have got a sterate 196. I have got a nice beautiful kit here and why I am using this is because it has this extra arm that I can attach to it and get inside a circumference. If you think about if I need to do something round and indicate the inside surface I can do it with this. Well I am going to set up to do this square block. Now we are going to simply come in here, put the block in. If you didn't see my other video on how to do round stock you should take a look at it. I will put a link up here for it. But we are going to simply just tighten this in. We are going to line the top of the jaws to the top of the surface. See how it lines up? Actually it is lining up pretty good. We are a little off there. I am going to back that up a bit. We have our stock roughly in place. Now we have to get measurements. This is where it becomes a little different than how you would normally do it. Is normally we would read on the outside surface. What we want to do is develop an inside surface that we can work with. The reason is if I bring this needle over on top, well every time I rotate I have a high point to deal with. If I can put it inside and indicate it, well we eliminate that problem. We are going to simply use some tape. Some aluminum bars I got here. You can use anything that you want for this part. We are just going to simply keep adding them. You will notice I have put numbers on these. I have put these numbers on there more for you guys than it is for me. Just so you can keep track of what I am doing. Now the reason I like to use tape instead of a rubber band is the tape doesn't have any flexibility in it. If I use a rubber band, I push against that and it is going to have some flex to it and it is going to give me a false reading. Now we are going to bring our gauge in and we are going to actually because this is not square, I am going to do the two opposing sides. Let's start out with worth number one here. Let's find out where it is at. We will line up on one. We are just going to zero it out here. Back to one. It looks like about a thousand is off. We have about a 20,000 difference. What I am going to do is I am going to push this in. Let's track it a little bit. 90. We are pretty close to that. Let's give it a little more tweak. Now we have got sides one and three lined up. Now we are going to do the exact same thing with four and two. We are going to just kind of get this needle set into place. It is that simple to line up a four jaw chuck with square material. Now you are going to have to experiment. You are going to have to just test it and have some fun out there. You can go out there and practice. You don't have to have something to turn down. This project I actually do have to turn something down and that will be in the next video. Alright you guys if you like this video give me some thumbs up.
