How do I do this without damaging the wood?
I guess it depends on the glue used. I've done it being very careful with a sharp razor. I nowc use fletch tape and wrap fore and aft. I just remove the wraps and scrape the remaining tape off.
I always just use a sharp knife and carefully scrape them off. I now use a utility knife with a carpet blade in it. That blade is curved and fits the shaft well. :coffee:
Most glues used on woods are a lacquer type. Put a little lacquer thinner or acetone in a glue bottle and run just a bit down the fletch base. This softens the glue and makes the fletch much easier to remove. BAK's carpet blade works well from there.
I read on one of these sires guys just dip the shaft in acetone-takes off paint and fletching-and fletching is reusable. Not tried it but it may be an option
