<p>Mike, a fellow could go that other step. It's a good idea, and I did it today. I glued a little arm to the lever.</p>
<p> </p>
<p>First, here's what the geometry of a (relatively) straight fret looks like:</p>

<p> </p>

<p>It doesn't take much effort to bend the fret to the smallest radius:</p>

<p>About 1/8" of movement of the lever equals about 2 degrees of radius:</p>

<p> </p>
<p>It's interesting how little movement is required to change the radius by a couple of degrees. I'm guessing that people who get good at changing radius get comfortable with the amount of pressure they apply to the bearing axle against the spring of the fret.</p>

<p>Thanks for explaining the nuts & bolts to me... it's a great idea. Now, couldn't a fellow go another step and mark the different radius points on the frame, where the arm would intersect them? It would take a little trial-and-error, but you'd have a repeatable reference for future radius-bending.</p>
<p>Unrelated note: it's always irked me (a minor irk, granted) that the first inch or so of the fretwire is 'sacrificed' before the bender actually starts creating the radius... so let's…</p>

<p>Simon, just to entertane a curious thought, would you be able to bend the fret wire without locking the allen screw; is there enough leverage to do so?</p>
<p> </p>
<p>Not that one would want to do so. Just a thought...</p>

<p>That's exactly so, Chris. Thanks for the explanation. The bearing is in a circular slot, and the fulcrum is in line with the center of the circle, so the geometry works.</p>
<p> </p>
<p>Moving the bearing with a lever instead of with its axle allows it to be moved very accurately and in very small increments.</p>

The pin is a fulcrum, the arm is a lever. When you move the arm/lever it moves the bearing, which is on a cam. Thus, there is no need to move the bearing with your fingers and wrench. At least thats how I see it.

Damn.... I must be denser than most folks had previously believed. What, exactly, does the extra arm do? And the little pin-thingie? I'm lost here. 'Splain it to me, Lucy.

<p>Thanks for your interest Pierre-Antoine, Rusty, and Donald.</p>
<p>I appreciate the thought Donald, but I've been paid well enough by the tips I pick up on this forum. Like these stickies on my computer about glue that I wrote down from Rusty's post. Etc.</p>
<p>I'd be just fine if the maker of this tool improved it for the benefit of users (and I'd be very surprised too.)</p>
