    For what poundage of crossbow though? I made some bolts before but for like prototype crossbows. However that being said I do know how to make my own bolts. I practice archery so the concept is pretty much the same even though bolts don't have a nock normally and are significantly shorter. Make the bolts as long as the track this will give you the best balance of stability. Bolts that are too short will tend to be faster but unstable bolts that are too long are stable but, too slow. I read in Ralph Payne Gallway book that the fletchings are an inch away from the butt of the bolt if I am not mistaken.

    I have made a target blunt 12 inch long bamboo shaft with a screw inserted through a horn washer,  I'll post a photo tomorrow.  I hardened the shaft and bound the end. Weight is maybe half an ounce, its too light to weigh.  Probably too light for.my 45lb crossbow.  It travels 30 m from a small elastic band pulled back 12".

    To make it heavier you could insert a headless nail since the bamboo is hollow. That's what JoergSprave did with his carbon arrows I believe.

    A good way to prevent you from losing bolt heads is to get whatever you are using as points as long as it has a sleeve that goes over the bolt. You can drill a hole through the arrowhead and the bolt shaft. Which then you will rivet in to place with a metal pin.

    I have already inserted a 1" long screw. I think I may have to go for a 14" shaft or even (for the first time!) have to buy some screw-in points. Alternatively, I could forget about bamboo and go with a solid wood shaft.

    Or you could make a composite shaft like the Native Americans did the foreshaft was a hardwood the main shaft was cane.

    I won't claim extensive experience, but I make a lot of arrows for my trad bows and have made a small number of bolts.  My crossbow is only 80# pounds, but I am happy making bolts out of wooden arrow shafting.  I use hardwood arrow shafts and standard glue on points.  I have also purchased the 1/2" Ash shafting that is sold for making atlatl darts and hand tapered the shafts to produce  barreled bolts. Purchase shafts made for heavier bows (80# plus)  and cut to length.  Taper one end for a glue on point and glue on a commercial point.  Arrow points are matched to shaft diameter and available in a wide variety of weights.  Ace arrow even produces bodkin points.

    Hi--  finally got my crossbow finished and went out to test
            A couple of small  problems but easy to fix
            The main problem is that the bolts fishtail badly
             Any ideas  ??
               Thanks   Sydney

    If your bolts are fishtailing or whirligigging, you have some sort of imbalance.  Most likely causes: either your prod (bowstave) is off-center in its mounting, so it's kicking harder on one side than the other, or you are drawing your bow slightly off-center, (pulling one side more than the other) which achieves the same imbalance.  Check you prod for centering.  If that's okay, stitch a colorful bit of thread around your string- center and make sure it ends up exactly in the middle of your lock.  
    If neither of the above applies, you may have bent/crooked bolts, crooked heads or badly fletched shafts.  I highly recommend going to the trouble of getting a decent fletching jig for making bolts... it's much more accurate than anything you're likely to cobble together inyour shop...even if you have to order overseas.  Good luck and enjoy your shooting.  Geezer.
