Topic tags/keywords: marking tools

I saw one of these circle drawing tools advertised, and am just wondering of anyone uses one in their shop. A practical tool to own, or a gimmicky waste of money thing that you use once, toss in a drawer, and never use again?

I suppose it would come in handy for a couple purposes none of which I ever see in your work. I’m not sure it’s interesting enough to me to buy one even if it had free shipping and only cost a couple bucks. On the other hand, If I only had one commissioned project that required multible circles and no compass hole, well, I’d probably decline the job lol

I’m not thinking of a use for it off the top of my head, but it’s early and I haven’t had much caffeine yet, so maybe I’m missing something…

I use a compass, a random round thing (usually a jar or can) when I don’t have a center for a compass, or circle templates when I need to lay out a circle of known size. But then I also wing it a lot, making circular things by taking a square, then planing off the corners, then planing off the corners again, then using a spokeshave to finish rounding. Or chucking up a piece of wood in my cordless drill and running it against the running belt sander if I’m in a hurry.

I don’t really see it. The smaller circles I need are usually cut using a Forstner bit. You don’t need to actually draw the circle you just need to find the center. This device doesn’t locate the center and I feel that a compass would serve most woodworkers better. Perhaps there would be some use for drawing scroll saw patterns, I wouldn’t know as I don’t have a scroll saw.

It seems to be nicely engineered but,...
I don’t see advantage on other existing tool.
You will also notice that it will not provide a real circle but a segmented curve.
What is the graduation on the ring for? Does it allow to measure the diameter of a circle?

Thanks guys. Yeah, it isnt something I need, just looked sorta interesting. Yes, Sylvain, it appears as though the gradiations are for precise diameters, just dial it in, out….

I think it is mostly aimed at artists, graphic designers, or someone who isnt a woodworker.

Compass and forstners get me by, most of the time.

Well, it seems to adjust quickly…I have compasses from my paper drafting days. For big stuff you can’t beat a beam compass.

A hammer is a hammer is a hammer? I think not, there are always many ways to accomplish the same task. Redundancy in tools goes all the way back to whatever the “beginning” is. Personally I like the uniqueness of the tool and its attention to quality. Thanks for sharing this device.

Why I thought it looked interesting. And it looks like a quality item, but is it really? One of the reasons I inquired about it here on L.J.s, to see if anyone had one and was using it.

Not only did I invest in a compass, but I splurged and bought a $7 drafting circle template for fast, precise circles. Nothing to adjust or jam. Just lay it flat et voila, a circle.

I’ll pass on that gadget until it comes with a six decimal place DRO.

As for the contour gauge I specifically told the better half not to get me one (or anything similar). I know the trick to scribe a contour using just a compass. Besides, normally you undercut the trim instead of trying to complex contour a tile.

The only thing I can think of where this might help is finding the center of a circle. Adding an acrylic/plexi-glass piece to the top with a small hole at the center, you could close this around a dowel or other circular piece that does not have a center point marked. Then poke a thin nail through the hole to mark the center for a brad point drill bit or a center for a lathe.

However, a regular center finder is much cheaper if slightly less accurate.

I don’t really see this as a woodworking tool. Maybe drafting, but just general drawing where the centers don’t need to be (or are not wanted to be) shown.
