Parnell -- Huh, I actually recently ordered and used the Shinto saw rasp, but it wasn't working nearly as quickly as I thought it would. That could be due in part to not having a vise or a proper way to weigh down the bow stave as I worked on it, other than to sit on it on top of an overturned bucket. Do you find you need to put a little weight behind the rasp when using it to get it to remove wood quickly?
Mo/Kyle -- I don't have a clamp or a vise, and I'm starting to think that that might be the problem; I'm starting to think that I don't need any extra tools to remove wood other than what I have, I just might need a vise to make the most of them. What I've been using to hold down the bow stave is just a 5 gallon paint bucket that I set the bow stave on and sit on top of. It hasn't provided enough grip for me to really put weight behind any given tool that I'm using at a time. I'm actually happy with the tools that I have if I can use them to their fullest, I was just going with the axe suggestion since I'm new to this and don't know quite how many tools I need to build a bow. Thanks for the suggestion, though! I'll keep it in mind for when I've got more I can spend on tools for bowyery.
DC -- Yeah, I've been thinking that that might be the crux of my problem (what with the work going by slowly). I'll consider the Workmate, but I did see a $20 vice that I might be able to clamp onto something on Home Depot's website, so maybe that could work? I suppose I can always go to the local Home Depot and see how good the Workmate is and if the vise it comes with would be suitable for the job. And if the stave ends up wanting to flip out of the vise's grip on the Workmate, I could always use c-clamps to clamp a piece of wood over workmate to hold down the bowstave (I think the jaws on it are made of wood, so I'm not sure how much grip they'll have).
Stick Bender -- Well, I can mark off the Shinto at least -- I ordered and received one of those the other week. Huh, I hadn't heard about or thought to use belt sander belts, though I have been using a spare block of wood as something to wrap my sandpaper around for use. Ah, thanks! That always seems to be the advice people have for whenever you get frustrated or impatient, and it's even recommended for programming (or learning it like I am), so I don't know /why/ I didn't think to apply it in this situation. I guess I just needed outside perspective. Hehe, I'm sure! Nothing quite like being able to use something you made yourself!
