Hello everyone! I?m looking for info on bending a tapered Cutaway ala Cumpiano with the Fox-Bender. Have already made normal Cutaways for Archtops,but have concerns about bending sides with different radii on the Bendingform.
After doing one tapered Cutaway on the Hotpipe, there must be something simpler.... .

Harald, what is a tapered cutaway? Pointy or rounded?

I *think* he means a compound radius cutaway. As in, if you've got a tapered heel, the part of the side with the cutaway follows the taper, and isn't perpendicular to the top and back. Basically, the cutaway becomes a rather more conic section of some kind, rather than a cylindrical one.

Harald,

You could bend in the odd angle with a pipe after you have completed the other bends with the Fox bender. Since you have to make a block that conforms to the angle anyway, you could use the block to hold the angle as it cools and dries after you ballpark it on the pipe.


I do hope this is what you guys are talking about?

I always touch mine up on a pipe. I tried to come up with a way to make the bender do it but alas I couldn't. Charles touches his up on a pipe as well so my guess is that there is no way to do it on the bender or he would have found it.

What ever happened to "Where there's a will, there's a way"?!

I haven't done it, but I was thinking about this kind of cutaway, so maybe I'll try. I would angle the plunger itself and keep the slats under tension.

When factories (furniture, etc) bend wood, they have a way of keeping the wood under tension. That's one thing that the Fox bender doesn't do very well.

Eric, check out the method that John Hall implements. (Bluescreek Guitars) I believe his bender holds the ends after a partial waist bend. Once the ends are secure, the waist caul is fully clamped.

Thanks all for your replies. It seems that I have no other choice for bending on the hotpipe. After a discussion with some violin makers, one came up with the idea to bend an normal Cutaway and then change the radius on the hotpipe. Thats the way he does when building a Viola da Gamba.

Wade: Great looking work!

Again thanks all. Harald
