reverse arm contours?

i think thats what they are called. to make sure we are on the same page, these: http://www.gwbasses.com/gallery/Dan_Bn_DC-1.shtml . i am curious of how they are compared to regular contours, as well as how you carve them. do you think it is a possiblity for my hollowbody bass? i have routed out the inside exept for wood for arm contour, with follows the curve of the shape of that par of the instrument, or like 90% of arm contours.
 
Hi.

The contour seems to be concave, if that's what You mean. I can't find anything "reverse" in there.
Providing the link is a correct one of course.

The one and only time I did something like that was to cover up an eff-up. The bit bit a bit more than it should've, so I had to blend it in.

A belt sander was the tool of choice back then, and that or a flap disk on an angle grinder would probably be my choice now.

Regards
Sam
 
I just used a ferriers file to do mine, which has a concave arm contour. I'll be redoing it when I get my laminate though.

could you show pics of the ferriers file? is the microplane rasp like a surform, or is is one of the drill press cheese gratters?

14"-18" Long,Look in my pics above, it's in there. Ferriers file (or Horseshoe rasp):

IIRC, a microplane rasp is similar to a surform, shaped like a file. Leave the cheese graters in the house ;)
