There is a learning curve.

However, after you get the hang of it, you can actually do compound radii as well. I simply check the nut and the 22nd fret with my radius gauges and verify with my straightedge.

I don't press the fretboard against the belt.

You must have superior hand/eye coordination for this to work.

I've done one (12") with a jig I built.
Other 12" hand sanded with the aluminum block from Stu.

And one (12") with this-Image

I stop building to build my shop so haven't
had a chance to do a compound with it.
It took no time to do the 12"...took longer to set it
and that was just a few minutes.
Still had to fine sand but it sure did a nice job.

I think one of my problems has been (both with hand sanding and with my trial run on the jig) trying to take off too much material. But again, I'm just not that excited about doing this process completely by hand. You may be Superman, but I'll assume the Batman persona and pull the bat radius jig out of my utility belt laughing6-hehe

I use a router jig (Rick Micheletti plan) and think they are worth making simply because I find them efficient and keep the dust to a minimum in the process. Hand sanding with a caul is not a bother either but with the FB already thickness'd and slotted, setting up to use the jig takes as long as required to mark centre, stick two small bits of 2 x side tape to the underside and to lower the bowl/tray cutting bit in the router to the surface of the FB. Once done, its difficult to see how any other method could match repeatable accuracy for a single cut radius.

Cheers

Kim

Thanks Filippo for mentioning sandpaper as well - When I started all of this stuff in the Summer of 2010, I went for budget paper at Harbor Freight, then got frustrated and started using 3M from Lowe's - I FINALLY used the Norton 3x a few months ago and it rocks - seems to cut quicker and last longer (Hence the 3X!)

Paper quality was my thought as well, Filippo. I'm using standard 3M stuff from Lowes. Not sure where it places in the paper spectrum, but it's sold all over the country through a major retailer, so it has to be good, right?! :lol:

As soon as you use the Norton Roger, your 3M will go in the "Hand-me-downs" box.

I hate to speak for Roger, but the stuff I used to get from Lowe's is green - and isn't the "stickit" yellow?

Stikit is color coded. It's yellow, green, and a few other colors as well.
