I was wondering when I'd see you here
I use my machete as a scraper and do fine, but I do all but the most delicate tillering with my farriers rasp. A pocket knife, draw knife, flat file for sharpening and round file for knocks complete my arsenal, and I do just fine most of the time. I have a band saw but I only used it to rip one stave.
My only advice is still to keep thinning those levers, you'll have some serious performance bows in no time.
