Mr. Sidmand,
Regards the scalloped bows....Most all of the Iroquois Nation used them, as did the Algonquian Language group (Odawa, Chippewa, Pottawatomie, Ho Chunk, Menominii, and most of the Great Lakes area like the Shawnee.
Scalloped bows were known by all of these Native Americans....but they also knew of straight bows, double curved bows etc. Elders have advised me that bows of this type are not much different than whites who have a fancy for different types of fireams....the style of bow was not wrote in stone it was a matter of personal choice of the carrier. By the way, the same can be said for the lack of grip wraps on most eastern bows....most were not but that does not mean that some did wrap theirs as a personal preference.
How the scallops are deployed is usually a give-away as to nation and/or tribe. Some were scalloped all the way up one side (with or without a scallop at the grip) and the size of them makes a difference.....some were on opposite sides one side upper limb and the opposite on lower limb. The only scalloped bows that I know of scalloped up both sides would be the Odawa (in their home territory and single sided for those few displaced to Oklahoma)
The best way to make them is to shape your front profile, then draw a line in 1/4" from the edge, lay out the scallop pattern, then cut them in no deeper than 1/4" line. Then the scalloped edge(S) should be thinned slightly like the back and belly have a "low crown" section. Then go back and cut the separation "v" ....do not make them deeper than the scallops, about 1/2 to 1/3 the depth is correct. If you are not 100% confident in your cutting of the V's (so you dont leave any sharp stop cuts) then I recommend the use of a file to make them........when all that is done make sure to smooth anything that even resembles a sharp edge.
Only other thing is if your scallops are cut already when you scrape the belly to finish tiller be careful or you scraper will make a whoopty-do at every peak of the scallops so make sure to have your "low crown" going on.

forgot to say....most all eastern woodland bows had raw-hide strings, a few had bark strings, and I have not seen one with a fiber string (doesn't mean that there never was any however)
