I build wood bows only, but I use hand tools when possible, which don't produce excessive dust (scrapers, drawknives, hatches, knives, etc.). When making dust, be it with rasps/files, sandpaper, saws, etc., I use a combination of any or all of the following:
1) Work outside on nice days
2) Wear a dust mask/respirator
3) Use a ceiling mounted air filtration system
4) Use localized dust collection connected to ports on my tools (via dust collector, vacuum, etc.)
5) Use a box fan with a good pleated filter on the back as an ambient dust collector. (This one is really effective and cheap! Just be sure to use a good filter that you're not blowing dust to kingdom come).
6) Wear a face mask, not glasses/goggles. The latter will often fog up on me when wearing a respirator/dust mask, plus they don't protect nearly as well as a full mask. I picked two up at Harbor Freight for $8.00. What a difference it has made, particularly in my knife making!
Hope that helps
