    I'll be using medium jumbo nickel silver Fretwire on my Hossenfeffer bass project. The fingerboard radius will be 10". I can get Fretwire already radiused to 7.25" or 9.5", is there a rule of thumb on how much to over-bend a radius? I'll probably be putting them in with a dead-blow fret hammer, FB is pre-slotted bubinga from LMI.

    I roll my own with a modified Waverly fret wire roller. I normally roll it to about an inch less radius than the fingerboard it's going in to. It isn't critical. You just want it to be a little smaller radius. The 9.5" should be fine. The 7.25 will work too; you can easily unbend it by hand back to around 9" R.

    Thanks Bruce, I'll probably get the 9.5" radius through LMI to make sure it fits their fret slots.
     
  4. I made a roller out of some washers, 2 bearings, a few bolts and some threaded rod. Cost less than $10 to build. Works great. Build you're own. ;)

    I seem to remember a link on this site for a set of simple plans to make an adjustable one as you describe. Anybody seen that link?
     
  6. I'll try and find a pic for you. It's beyond easy.

    I'm highly opinionated and extremely self-assured
    I'm still trying to figure out why this is an issue. I buy fretwire and it arrives in a large coil. The radius of that coil is smaller than the radius of my fretboard. I cut off what I need, hammer it in, and it stays. Done.

    What am I missing?

    Yeah, I agree. I get my fretwire from Jescar, and it normally comes through rolled to about 6" radius, which works fine for most of my basses, which are 7 1/4" radius fingerboards. But I do some 4" radius fingerboards. For them I roll the wire down to about 3 1/2" R. When I occasionally do something flatter, like 12" or 16", I'll "deradius" a length by hand to roughly 10" R. The amount of overbend isn't a critical thing.

    I'm probably agonizing over something irrelevant, as usual. This will be my first neck-through from scratch, and I can't afford to trash my expensive materials, hence all the noobish questions. Thanks for humoring me.

    Here is a bending jig I made a while ago:

    Some small pieces of metal, some ball bearings and some screws is all you need. Note that the brass piece have a small slot filed into it for the fret tang to fit into so that the tang isn't damaged. A set of ball bearings would probably work better, though.

    The wire Warmoth sells is already bent to the radius you need.
     
  12. This is a quick&dirty one I made a few weeks ago.

    Just piece of Plexiglas with three brass rollers attached to it, in the rollers I cut a groove for the fret tang.

    The roller with the handle on it is adjustable from the back (the roller itself is not present in this picture).
