Stringing Tight Curves

Topics:Blog, Dave, Inlay, Tip, Woodworking, federal

While working on my federal table last weekend, I set my sites on inlaying the curved string on the apron. After several attempt at trying to make the radius buy misting the string and using a soldering iron (and breaking each and every string) I gave up.   I was licked and all was lost.

At this point I was seriously wondering why in the world I didn’t just go with three rectangles on my apron instead of getting fancy and laying out curved ends.

So I stomped into the house and started digging up all my books, magazines, printed internet articles, DVDs, VHSs anything do to with inlay methods of work and found – NOTHING!

That was until I sent a distress email to Glen & Chuck asking what in the world I could be doing wrong. (After all I had bent lots of stringing using an iron before.)

Then the suggestion came to think bigger!  So with that I traded in the soldering iron for a piece of pipe and torch.  And the following is a step by step process on how I was able to make the curved inlay.

Step 1: While soaking my inlay in hot water I put a piece of pipe, about the same size of the bend I want, into a vise and heat it using a torch.

Heating Pipe

Step 2: After the pipe is heated I take a piece of string and using a piece of flashing as a backer I set the middle of what is to become my curve on the pipe.

Stringing Flashing Step 3: Using constant downward pressure I slowly pull the string around the pipe. (You will hear sizzling at this point.)

Bending String Step 4: I hold the two sides together with one hand while rubbing the back of the flashing with my other. (Think of it as trying to rub out a crease. But be careful because the flashing will be hot!)

Step 5: Release the pressure and take a look at your curve. Make sure it doesn’t have any cracks or splits.  (If it does you either did step 3 too fast or the pipe has cooled down too much.)

End Result

Step 6: Cut it length and install it.

Once I completed this I went back through all my resources and I found at least 3 different places where this method was demonstrated.  (Why is it you can never find anything when you need it?)

    Dave,

    I have only ever installed stringing into solid wood of the primary species. I have a few designs on the books that will require veneering like in this demilune you are making. Do find any difference in scratching the channel for the inlay with a veneered surface. Does it splinter at all?

    If you rush through it, it will splinter very easily. Especially since the veneer was applied to the apron at an angle.


  • I am rather new to woodworking and it will be some time before I am attempting anything so difficult. That being said, I enjoyed reading about your triumph.
