Bastard file or rasp?

[Kopper1013]

Anyone use these on a fiberglass backed bow?

I have a 14" bastard and large rasp I was thinking about trying to run down the sides to get my limbs to get them real nice and straight (I have trouble with my small belt sander not creating high and low spots) has anyone tried this or am I just gonna pull up a bunch of slivers and make a mess of my limbs?

Thanks

After I cut out the limb profile on the bandsaw, maybe grind it some on the drum sander(adapted drill press), I like to use the smoother side of an older, partially worn out farrier's rasp, held almost parallel to the limb, to level the edges of the limbs(I never use good, newer, sharp tools on glass).

Used properly, the farrier's rasp levels and smooths at the same time and the resulting 'shine' makes it obvious where more work is needed to establish a perfectly flat edge with no low spots.

Sometimes I switch back and forth from that to a 10, 12, or 14" double cut bastard file... it all depends. It's hard for me to say because I switch tools by feel/instinct, I've amassed a good collection, and all are within arm's reach. I use so many files and rasps, I don't like to choose just one for any certain purpose, or even advocate just one or two. I think we should each have an extensive selection/collection and use whatever feels appropriate at any given moment... upon whims... like an artist in a flurry of paint, palate, and brushes, and tomorrow the same situation or idea may see a whole different arsenal employed.

Be careful with rasps on glass bows... even rasps as finely toothed as a Nicholson #50, because they can lift a detrimental glass splinter in a split second.

I HAVE used such rasps on the riser sections, but very carefully/consciously.... always running a single forward stroke from glass to wood.

Have not done much with glass.  My course file has been indispensable when it comes to fine work and getting out the rasp gouges.

You could use a piece of hardwood and glue coarse sandpaper (I use sanding belts cut to the dimensions of the wood) to it.

Yes I have used (used) sanding belts as well works great because they are made from a tougher material.
