Questions & Answers
On one side are few fences that form a 90-degree angle, while on the other side there is a 60 degree angle. There is a slot in between the fences that cuts the angles in half. As a result, a line drawn along that slot would pass through the center of the turning square, circle, or octagon, whichever shape you have. Rotate the device 90 degrees and draw a second line. The intersection of the two lines determines the turning center. Getting close to your goal is this. For more accuracy, you can draw four lines at right angles to one another, resulting in a tiny square in the middle. If part of the turning square must be left at the beginning, accuracy of this degree is needed. If you don't, the squared-off section will not line up exactly with the turned part.
It is squiggly so you do not mistake it for the actual center line and make the wrong mark. It is just the other side of the gap that allows you to put a pencil or other device in the middle to mark the center line.
You should be able to do half rounds if you take your time and measure carefully. The 3/4 I've done so far have been trouble-free.
This tool probably could be used for that as well, but the only problem is it is fairly large so the smaller the coin, the more difficult it will be to hold it in place to In my experience, it works properly to mark centers on rectangular pen blanks about 3/4" square, and it also works on round blanks about 3/4" in diameter.

This tool is not working as it should. This tool was purchased to find the centers of legs as part of a pet item I made. It just made sense to assume center was the In the meantime, I was able to make a couple of push blocks for my table saw this past weekend. In order to do so, I cut some oak off a couple of pieces. This tool was used to mark center at one end of the lines, and then the other end. It is true. This is how I roll - Across the block, an angle appeared in the edge. It makes sense. In order to check that the block was correct at all 4 corners, I used my square. The truth is that it In order to mark the other side at the same angle, I marked the other side. Eventually, I came to the following conclusion Taking a 5-degree angle and flattening it There are still six blocks to go. In every single one of them, there was a definite ending. Start by drawing an angled line, confirm by measuring the center at each end with a ruler. As a result, I placed my square right on top of the center finder- As it turns out, there is a subtle issue. An acute angle of 90 degrees. Even though it is minor, it is of no significance - An off switch is an off switch. On Larson's website, I posted a question and received a reply saying they would check it Despite the fact that it is Wednesday, I have yet to receive a reply. Recently, I replied to a post asking for help. I cannot upload a link to my video to YouTube or Amazon, and neither of them will accept my video. has yet to reply to my message via their contact page, nor did they ever respond to their Facebook comment saying they would look into the issue.
It is a durable piece of plastic, which is more than adequate for all its purposes. One improvement would be to outset the marking edge from its dead center by a small amount so as to accommodate a pencil's half thickness. Turners use a variety of marking instruments, which vary in thickness, so it is not possible to do this with perfect accuracy. If you mark the end of the blank in all four directions, the square will be a little smaller and more accurate (by virtue of the marking). In most cases, this is not that critical if the whole turning is going to be turned around. When one turns a piece that will remain partially square, or when remounting an already round piece, then getting the lathe centers just a little off will yield excellent results In the final work, the center will be visible.
Provides you with a guide to This program does what it is supposed to do. The center of items can be found with the help of this. Since the guide runs exactly down the center, you might be able to draw a line that is just slightly off depending on what size pencil you are using. A line drawn from each corner of a square represents the exact center of a square. If you draw a line from each corner, you will end up with a tiny square in the middle that represents the center of that square.
Whenever I turn a piece of wood, I use this method to determine the center. The interface is straightforward and easy Definately not a real space hog, and it isn't very expensive. Unfortunately, mine cracked when I dropped it on the floor, but perhaps it would be more expensive if it was made of stronger materials. ***** We get perfect results on round and square stock. For OUTSIDE stock, it's a little more difficult. I choose two of the widest paths on the item I intend to turn each round. From here on out Using all 4 corners of a square piece of stock, I mark the center. In this way, I will be able to get close to the true center of the circle.
It is without this tool that I would be hopelessly lost, unable to center my holes, and, in the end, I probably would spend the rest of my life wandering around in the woods. Now that I have found this plastic center finder, I can rest easy knowing that my holes are centered and my rings are evenly built.
I had put off buying it because I thought I could buy a tri-square combo for a reasonable price, but that's looking less and less likely these days. [Got one for $ 12 in the US There was no value in it. I like it because it's simple, it's easy to use, and it's reliable You don't have to spend a lot of money on it.

The tool I misplaced, so I bought a new one.
I like it, but I misplaced it Now I have two of them because it is the same. There are a lot of options and it is very quick & easy A very easy to use application. According to the company, it was on its way out. I think that would be a serious mistake, because this is an excellent tool, even for a low price. *BTW the replacement tool is the POWERTEC version, which looks and feels just like the original. The cost is 50 less, but the function is the same.
It has proven to be somewhat useless to me as a turner, at least. In other words, unless you square your blanks properly on a table saw, you won't be able to use this tool perfectly. My blank is usually cut on a band saw or on a table saw, or both sides are cut on the band This is a good product at a great price but it is not the best. What are my regrets about buying this item? There is no. There is no need for this at all. My usual method now is to eyeball the center of the circle.
There were multiple places I looked for a center finder, Lowe's, Home Depot, and I couldn't even figure out what it was from anyone I asked. Upon looking it up online, the Lowe's guy was surprised to learn that this is exactly what it is I really like it. The center of the bottom of wine bottles is found by lathing (finding center of bottom of bottle).
