    In preparation for my first crossbow project I'm practicing rolling the nocks.  This is just a test piece, to practice the technique and work on the shaping.  The stock is approx. 3/4"x1/4" mild steel from out of the scrap bucket.

    It needs to be cleaner, and it took too many heats, but that is something I will work on in the next few practice runs so I have it down before I do it in carbon steel. 

    What about the shape?  I'm working mainly from images, I've seen originals but don't have any measurements to work with.  Just in terms of proportion here, should the flanges between the flat and rolled parts be wider?

    Since I've never done any real smithing, I'm impressed and jealous of your obvious skill. I've got no firsthand experience with that type of prod end, the only thing I see that might be a concern is where the join widens into a gap just at the shoulder, which I think is right where the string would rest. I think you would want that area to be completely smooth and featureless so as not to cause undue wear on the served loop end of the string. So extending the join well past the shoulder join would probably be an improvement, IMHO.

    Thanks!  Yes, I see what you mean.  I can refine that shoulder which will close up the seam, and should also make the transition more defined requiring less cleanup at the bench.  The final piece will be sanded smooth.

    Greetings from a fellow smith! Nice work on the rolled nock...I just got done forging my first pair as well, which look an awful lot like your practice piece there. They work fine, but the string sits at the very bottom of the rolled-up part, it looks a tad insecure. Next time I'll draw the 'ears' out wider and flatter at the transition area. 

    Also, I used 1/4" stock and ended up with an extremely low draw weight (under 100#). Go with at least 3/8" stock if you want decent speed out of your bows...

    And keep up the good work! Nice to see someone else tackling a forged prod.

    Thanks, Orien.  I intend on tapering the prod from ~1/2" at the center to 1/4" at each end, with some taper in width but not a great deal, which seems to be in keeping with several originals I've seen.  Since I'm doing these with my brother (him the woodwork, me the metalwork) we need to decide on the details of design still, so the dimensions aren't set yet.
