this is something I really enjoy doing. I cap and crest my arrows and then fletch them. I do as much work on my bow as I can too. I own a bowpress and a fletching jig and will soon get a bowvise and centershot laser.
Just last week I bought a Bitzenberger jig. I have owned a Jo-Jan for several years. There is no comparison. The Bitz is so much easier to use and much more consistant. It is a well made product and should last a lifetime. IMHO it is well worth the extra $$. I was using wraps until I read the thread instructionalGreg/MO posted about cresting and capping. My arrows look so much better now and are much more enjoyable to make. I also know that no one else will have arrows that look like mine. I take pride and pleasure in my equipment and you will too when doing it yourself. Goodluck and post pics of the finished product.
