I have never removed the nocks while installing the inserts. To be clear, I’ve only had the issue of the insert sliding forward a 1/64” during cure once but it was recent. I just assumed the insert stuck a little to the insert tool when I removed it due to excess glue. When others mentioned vacuum as the possible cause and Gooserbat recommended pulling the nocks during installation it made perfect sense to mitigate pressure from inside the shaft. I’ve always made certain to keep them horizontal during the entire cure time so they don’t move due to gravity...
I’ve only had this issue once, and the shaft is still usable with one 5 grain brass washer. However, now that I’m aware of it I will take additional steps to ensure it never does again! By the time you get wraps, fletching, footings, inserts, tuning, broadheads, etc.... You have a lot invested and riding on these babies. I want them precise and they have always served me well. Thanks again everyone!
