RE: Homemade Lighted Nock review (w/ pictures)
I make mine very similar to that except I go to the craft store and buy 1/4" wooden dowel cut it down to about 3/8" long pieces and insert them inside the arrow shaft. The dowel weighs maybe 1 grain and I do not have to use any glue or anything. That way if I have a Thill light go bad which they wil easily do, all I have to do is remove the nock and replace it. Also I don't have to use 2 nocks to make 1.
