Thanks for the replies guys. Lots of good info on where I can get materials on here. This is my first posting on this site, so thanks for making a newbie feel welcome.
For my current arrows I'm using Canadian tire 5/16" dowel with fletchings i bought from 3 rivers (full length black and white feathers - i get 2 fletchings per feather). I've also got feathers from Archer's Nook in London,ON.
I'm now making my own shoot shafts from various woods, and am looking for a source wild turkey feathers to fletch them and real sinew instead of artificial to tie on those fletchings. Just so they look a bit more "authentic", but I guess Canada good feathers would be just as good.
The rawhide I wanted to use to make bowstrings. I think goat rawhide would be good for bowstrings as it's a bit thinner than deer rawhide and cow rawhide? There is a butcher near my house that has whole goats skin still on hanging in the window sometimes - I should talk to them.
I threw in some pics of what I'm using right now. The bow is the first one I made - after about 5 "peak and tweak" sessions. It's elm, 62" ntn, 45#@27. Linen string (pyrosupplies) with artificial sinew serving and a little dogbane "wind indicator". I backed it with cotton canvas that I painted black that an artist friend of mine gave me. In retrospect, I don't think it needed the backing, elm is tough stuff, and I love it, but I wanted to be safe as I went through a couple ash and hophornbeam staves before this guy. This was the first live tree I cut down and seasoned indoors. The other stave (which all broke) were found cut down already or I seasoned them outside.
This guy started out 68" ntn with giant nocks and horrible tiller. It kicked like a horse, was 30# @27 and had 3" of string follow. After I made a few more bows from the rest of that elm tree and read all of the other TBB's. I revisited it and turned it into what is now my favorite bow. All thanks to Marc St. Louis for his article on Heat treating, it saved my bow!
The arrows on the right are just canadian tire dowels. The left are my newest batch of chokecherry shoot shafts. Gonna fletch those up right after this.
