I did one with a GT nock. Took a full length cedar shaft and fitted a piece of GT shaft about an inch and a half by grinding the shaft to fit the internal GTas closeas possible. Ensured it was square and glued it on. No reason why a lighted nock could not be fitted in the same manner. After I got it, I retuned the shaft for length due to the difference in weight. It seems to work It took about 40 minutes total to get it to square at the shoulder. The strength of the shaft did not seem diminished and I had no fear shooting it out of a 54 pound longbow
