If your just starting out with carbons, you don't need to epoxy the inserts. I have used hot glue ( I use the round chunk that 3rivers sells)for the last 5 years with no problems. Take a small nail and some fine sand paper to rough up the inside of the shaft apply heat to the insert only and keep a small container of water next to where you are working. After you place the insert in the shaft, dip it in the water to cool.This way if you deside to shorten your shafts, you just heat the insert tool screw it in the insert and wait a minute and pull it back out. If I break a shaft I cut the shaft down for kids arrows and reapply the insert.
