Interesting wire bending tool

I've seen that in the Duluth catalog and in some tool catalogs. Seems like a good idea, but I've always just run a 2×4 over the table saw and made my own. I'd use oak if going all the way to 3/16".

I don't begrudge them $7 for a handy jig, but I've never wanted to wait a few days and pay $10 for shipping so I DIY.

For those radiused sections: use a hole saw in your wood block, say a 1" diameter. Then, using the same pilot hole, use 1-1/8", 1-1/4", etc. Trim the random thin bits away with a sharp chisel and you'll have a perfectly circular core as a part of your jig.

They have 4 positions for 2 studs of fixed diameter. Bolts are CHEAP. Holes are free. Give yourself lots of options by dropping various diameter bolts into numerous holes in your jig. Heck, don't stop at bolts – step up to 1/2", 3/4" and 1" wooden dowels.

Try a set up with coat hanger wire first. When you've got it dialed in, use the good stuff – stainless or Ti. Or just paint the coat hanger wire!

Now THAT is an assumption!
You can bend Ti wire, but it might take a bit more than that jig.
Try to bend Ti welding wire sharply and you may have 2 bits.
Try to bend it in a curve, and you may need to go 30-50% further than you think, and at a much smaller jig radius.
Ah, it's fun stuff!

I find it much easier to bend alloyed Ti wire with heat from a propane flame. The heat relieves the strain and the wire assumes exactly the intended curvature rather than bouncing back as Roger mentions. This would be difficult if you need a jig for a special curve, because an aluminum jig would steal all the heat and a wood one would char, but I've made Ti wire corkscrews and all kinds of angular bends using just pliers, a steel tube, and a propane torch.

Colin: Good point on heat loss to the jig. An old cast-iron item and an abrasive wheel in a circular saw come to mind for a DIY jig. Cast-iron would conduct heat considerably less than aluminum but handle a very high heat. Steel would be more conductive than cast iron, but still much less than aluminum. You could also pre-heat any metal jig beforehand to reduce the heat loss from wire to jig.

And/or a few layers of metal foil would give some insulation from the jig. Better yet, some mineral-wool tape as is used to seal exhaust pipe leaks (available in a JC Whitney catalog). Or scraps of fiberglass cloth/batting I assume we all have laying around could insulate the wire from the jig.
