This video has been making the rounds and since we all need to use a Rasp, here's a Master using them on a table leg:

As Tarhead contacted me and invited me to join this discusion, here I am. Please feel free to ask any question about rasps, I'll do my best to answer.

He also mentionned guitar neck shaping. On this matter, my advice is to use rather a half-round rasp than the usual cabinet maker rasp, as its tighter radius fits better to the tight curves on the extremities of the neck.

So how do numbered rasps like yours equate to Nicholsons numbers? My Brazilian 49 and 50 are much better than stuff from the depot, but I keep reading it's another leap up to good rasps. I'd probably want one faster and one finer. So what compares to those, and what would you recommend?

Thanks,
Mike

Here's a scaled pictures of the 15 different stitching grains :

To answer more directly your question, the closest equivalent in my production to Nicholson 49 and 50 are cabinet makers rasps of 10" (250mm) with stitching grain 7 and 9. So a 12" cabinet maker with grain #5 will be I think way enough faster. On the opposite, 8" cabinetmaker grain #11 should leave smooth enough surface.

So, can you jump from a #5 to a #11, or does that make you frustrated like skipping grits using sandpaper?

No, in my previous answer I assumed that you can still use your Nichoslon rasps to cover the gap between stitching grains #5 and #11
My recommandation is to go by difference of 3 numbers between stitching grains : for example rasp #5, #8 then #11 then #14.
