On a banjo with a Radiused fingerboard, how is the transition from the 1st 4 frets to the rest of the neck done? I have looked at some videos, done by Guitar makers, explaining how to radius a Guitar Neck but of course a guitar has the same number of strings from the zero fret all the way to the body.

When making a Radiused banjo neck, is the radius only on the 1st string side and the 4th string side relatively flat all the way to the pot? I would think, otherwise, there would be a problem with the 4th string coming in contact with the fingerboard somewhere around the 5th fret? And then, of course, I am guessing the radius would extend across to the 5th string from the 5th fret all the way to the pot...

I have seen some conversations here about the pros and cons of radiused necks, but I can't find much on the specifics of what goes into making one....

You radius the blank first, as if it was a guitar fingerboard, then profile it with the cutaway before the 5th fret.

If it's a multiple radius, the 2 or three radii blend into one another so that a straightedge will always make contact along the full length of the fingerboard at any point.

I've never been brave enough to attempt a compound radius. With a plain radius I cut out the profile before making the radius, as I figure there's no need to spend the effort making a radius on wood that is going to be cut off. The height of the fretboard at the side of the neck on the bass side will be greater below the 5th fret than above it, or on the treble side, but not enough greater to be glaringly noticeable. Of course the smaller the radius is the more difference will be present.

Thanks for the information Ken and Zach. I have a couple of tenors sitting around and I have been thinking about trying to make a radius-ed neck for one to see what it is like, I know there are easier ways but I like to tinker too.

Also. Thanks Ken for putting your illustrations / pictures up with the explanation. A picture really is worth a thousand words.
