Post subject:  Side-Bending Jig Question

I'm working on my first guitar-building project and recently purchased the Fox Universal Side Bending Machine. I built the template-jig (photo attached) today but had a question before I try this out. Two of the steel rods aren't perfectly flush with the side leaves. In both cases, the circumference of the rods project about 1.5 millimeters beyond the top-edge of the side leaves. Is this something I need to fix before going live? In other words, will this tiny projection end up causing a crease (or bump) in the rosewood when I bend it to make the sides? Or will a projection that small not really make a difference once I clamp the sides into the mold after bending. I'm hoping that once I bend the sides and then clamp them into the mold, such tiny imperfections will be evened out. But I figured I should check first before I risk ruining a nice piece of rosewood. Thanks in advance for any advice.

Greeting Sam and welcome to the forum.
Are you saying that the diameter of the steel rod is not tangent to the contour of you template?

James -- thanks. And yes. That is correct. It is not perfectly tangent. Hopefully my pic below makes it more clear.

Probably won't make a bit of difference, but I would fix it just because it would bug the you-know-what out of me.

Cheers,

I would fix it, why take the chance that it will cause a problem.

I would file the holes down a bit to get the rods flush. Otherwise you could have a slight skew/twist on your finished bend.

My tuppence worth.

If you are using a building mold or form you are fine and you won't need to do anything as the mold is what will determine the shape anyway .

I'd grind it level, but as John says it won't really effect your side much (they move quite a bit no matter how well they're bent). If you ever try to make laminated sides, though, you'd best be sure your form is spot on.
