I don’t know what YOU might call it! My dad called it a Bow Line! (Not a boline, that is a knot)) I use it to fair a curve. Here is his design (and mine) simple and sweet, one piece of wood, four holes, one string!
Speak up, improvements? Caveats?

Actually Dez, I have one of them. I got mine from Lee Valley;,42936,50298&ap=2.
I remember also having one like it when I was an apprentice Draftsman years ago, it was a standard issue curve drawing aid.
They are very useful and provide quick results. Good to see someone else using one.

Cool! But how do you get a consistent curve?

Jim, They do indeed and far cheeper than “paid for” versions!
redryder, They gotta be wimpy little intuders!
Roger/Rex, Mine cost less! Works the same! LOL!
Topa, If you use a uniform grained wood and are careful about the thickness you are pretty much assured a uniform curve – at least within the limits of the human eye!

I have been meaning to make one of these… from some old wood venetian blind slats that I have salvaged and saved.

Nice of you to post this idea, it comes in handy.
I saw this on The Woodsmith Shop a little while ago.
And then I used it to make the curve on this shelf.

Oh, and the I love the boline’s knot, learned it at fire training, everyone should know this knot.

they are called drawing bows, and they are quite handy, youve made a nice one. you can make one for asymetrical curves as well by tapering the thicknes of the material from one end to the other, very usefull. if u make a wooden block with some holes in it, and run the line threw it u can have infinate adjustabillity.

I have used these for many years and you can also copy and re-produce many curves easily. good to make them in different lengths.

This one is a type of Mahogany, not sure what kind though.
It is nice and straight grained which helps in getting a smooth curve.

Like Rob said you should be able to adjust the curve by making them thicker or thinner down the length. Thinner should allow for more curving while thicker should resist curving. If you had a stick that was 1/4 inch thick on one end and 1/8 inch on the other there would be more curving on the thin end. This is a great tool. Thanks for sharing.

I always called those “fairing sticks”. Mine are Masonite as it has no grain and bends uniformly. I’ve also used an aluminum strip which works very well.

I’m so glad you shared this, Dez. I have bent a piece of wood to get a curve, but this is a perfect example of how the simplest ideas often slip right past me… tie it with a piece of string! I imagine it would be a fun little project to make a set of these to accommodate a variety of ranges of curves.
