I currently wiped the dust off of the 45# ben pearson recurve my father handed down to me and started shooting it. currently it has a 12 strand bcy b55 flemish string and 27" easton storm 500 arrows with 100 grain tips, and 4" vanes. My problem is that when i release the the nock end is sort of goes up and down. Anything is helpful. I realized that I'm not going full traditional, I just wanted to get into it as cheap as possible, so I'm using the arrows and heads from my compound setup.
Shooting off the shelf you have to use feathers...no vanes. If you want to use vanes, put a stick on elevated rest on
I decided to remove the brass nocks and tie on 2 10 knots for knock points so I can move them just by twisting left or right. I decided to move the nock point up, when i originally put them on the top one was only 1/4" above level and I kept moving it up until my arrows weren't hitting nock high.
Thats the way to do it but if you have a bare unfletched shaft that will tell you even better. If you are shooting plastic vanes then put the cock vane towards the riser. The flex of the arrow as it comes off the string will clear everything that way. Shooting cock vane out will almost always cause the bottom hen vane to contact the shelf and that will also give you a false nock high.
X2 on feathers. they are a necessity. Also your point weight is too low. For that spine arrow you really should be shooting 125-175 grain heads.
