I was wondering if any one had fletching jig they liked or would recommend for fletching bolts? Or had an idea to get any jig to work? The jig I have doesn't work so well for bolts. I have made it work but that was really just eyeballing the fletching parallel. So most of the bolts turn out fine but I always have that one that flys like a drunk hummingbird.

Unfortunately I can not offer any advice towards any off the shelf fletching jigs.

However, I have made a fletching jig for my cane arrows that was dead easy to make and cost me nothing at the same time (aside from an hour of time that is). I shall try to upload a pic as soon as ive read the FAQ on how to do so .

Basically i used an flat pine board (from a pallet), cut a length 180 long for the base, then two smaller squares for the ends. In the center of one square i drilled a 8mm hole (nock locator hole), repeat the same for the other square but also then cut an offset slot (think L shaped) joining the hole to an outside edge of the the peace. Hot glued the two squares onto the bigger boards, making sure the holes lined up. (Mine also has a 8mm dowel sanded down to be a nock holder for nocked arrows so we wont need that). quickly print out a hexagon from google etc showing the triangle/angle lines, mark every second line for the 120" angle for your fletching orientation, glue it to the end with on the small hole in it. Now glue another peace of wood along the top as a bar between the two end (mine is offset), snap the cover off of a cd case, cut it to suit the depth and length of the fletches your after. then lastly use a small bulldog clip or spring clamp to hold the cd case (fletch clamp) to the bar on top of the jig. Its a bit slow and fiddly but for free who cares Hope this helps....

Will try to send up the pic shortly.

Here ya go... its ugly as sin, yet it doesnt mind how its treated, its currently set for a heavy right wing offset. I Initially made to see if it would work and if I it was worth the exercise, which since it does Ive left it alone ever since

The nasty little jig above can do this




Right wing off-set with four inch feathers in three and four fletch configurations, my interest in making myself a crossbow will be the pleasure of letting loose my homemade bamboo bolts out of a home brew crossbow getting my own dinner spline wont be an issue as i foot the interior of the bamboo arrows and bolts with hardwood cores. But that's a separate topic for once Ive finally gotten my act together and have a working crossbow to experiment from.

Naw the real beauty is in the result. I do like that little device, Those are some nice looking arrows.

Fletching jigs for crossbow bolts? For many years, I used a pair of Bitzenberger jigs, with the stops set to 90 degree angles. So how does one get nockless bolts to index? I tapered the butt of the bolt to accept a nock, which I simply jammed in place... no adhesive needed. In fact, I found the easiest way to use the jig was to avoid the built-in stop mechanism. I simply jammed on the nock, fitted it into the Bitzenberger's receiver, fletched one side at the required pitch, then Gently pulled the bolt out of the receiver, being careful not to disturb the nock, turned it over and fletched the other side. When the fletching is dry, examine the bolt very carefully. If everything looks straight, cut the tapered bit off the tail and proceed normally.
These days, my friend Jim Atwood, at Oldenbolts fletches most of my bolts. He uses a battery of Greyling jigs, equipped with crossbow-adaptors that hold the butts securely. The Greyling jigs are substantially cheaper than Bitzenbergers, and work quite as well, though they might not last as long. They have adjustable stops that reliably hold bolts at the right angles for fletching.
You can of course build your own jig. It isn't difficult, and you can always use temporary nocks to index them consistently. The trick is: if you build your own jig, it's got to be Tight and Consistent. If there's any play in the vane-clamp, you'll get erratic placement of your feathers, which will result in poor flight. If you're making traditional two-vane crossbow bolts, your feathers are either absolutely right, or your bolt will fly very badly. If you're making three or four-vane bolts used by some modern bows, having one feather a little off may make your bolts fly a little off, but they probably won't go entirely haywire.
I would recommend looking at the Greyling jig for starters. It's easy to use, cheap, and gets the feathers on jussssst Riiiight. Geezer

I too have used a Bitzenburger jig for many years and have made an adapter which receives and holds the round flat ends of my crossbow shafts in register. But although slightly off-topic I am interested to know what or which adhesives any of you might be using? I am now using Loctite Super Glue Ultra Gel in order to get soft plastic vanes to stay on FG shafts, under the harsh punishment that crossbow arrows often endure. I know all about cleanliness, acetone and all that, but it seems as though nothing I have found yet is perfect for all applications. e.g. wood, FG, aluminum or carbon, in combination with a variety of vanes; whether they be synthetic or natural in origin. Maybe I'm asking too much. But please fire away, because I'm all eyes and ears.

Hey thanks for all the advice.

About the glue. Not sure if one glue is going to solve all your needs. I like Ducco cement for attaching feathers it seems to work well and takes the abuse I put my arrows through. But that is feathers on wood, not sure how it works for other things.
One glue I think might work for you is MAXI CURE IC-2000 CyA (http://www.lancasterarchery.com/product_info.php?products_id=10314), it supposedly has shock absorbsion properties and doesn't get as brittle as other glues. But have not personal experience.

I have used Graylings for about 2 years with no problems. They're inexpensive and come come with the crossbow bolts adapters. I believe that I've fletched over 100 dozens of bolts and my set of 6 jigs seems to be working as well as the did on the first bolt. The only problem that I can see with them is that the rubber in the bolt holder might wear out.

I bought mine here: http://www.bowhunterssuperstore.com/fletching-jigs-grayling-c-43_174.html

• On feathers and plain wood: I have successfully use ZAP's ZAP-A-GAP Medium CA+. Apply a small amount to the feather, hold with pressure for 10 seconds, then let it set for 1 - 2 minutes. I have torn off the feather through the quill, and I have torn off wood on the shaft, but I have not seen the bond let go.
  
  
• On feathers and LACQUERED wood: I have successfully use Duco Cement.
  
  
• My experience with CA adhesives and 3Rivers house-brand lacquer is that they DO NOT PLAY WELL TOGETHER! I have experienced very slow curing, and very weak bonds.
  

BTW: I'm Jim with OldenBolts, and I do most of the bolts for Geezer / New World Arbalest. If you want some bolts, send me a message.

Riot, those are some nice fletchings....though one thing I can't get through my thick head is - how did you offset the feathers so much with a straight clamp? or am I missing something?

Hi Ivo.

Glad you like the looks of the fetching, Im rather chuffed with them as well (even more suprised at how well the four 4" fletchs travel - aka nicely

The clamp Ive been using is a straight bit of Perspex that I had laying about rotting in the bright Aussie sunshine.
I found that due to heavy offset angle ive got in place with the top clamp bar and with the diameter of the bamboo being a bit larger than your normal shafting, that i needed to firmly clamp the feather ends with about 5mm more fletch exposed than the center section to help allow for the curve in the shafting and the clamp angle (note: there's two small bolt holes in the clamp for just that job and is annoyingly the most fiddly thing about my nasty little jig).
Yet doing the above also seems to give the feather a semi-Helical look once its all done as the fletch tops then try to flex into alignment with fletch base. So its like a wild blend if a straight offset yet with a semi-helical appearance. I have tried bending some perspex to allow for a true helical finish (fletchs in a straight alignment from front and rear of the shaft yet curving through the center section when viewed from the rear end) yet all I ended up doing was just burning my fingers trying to get it all nicely matching.

Ahhh...I get it now.

So technically you just set the desired offset angle and press a portion of the feather onto the shaft and then wrap the loose ends around the shaft following the direction set by the jig...simple and to the point...good stuff and most importantly it's very versatile since you can set the jig to any fletching offset angle.

The four fletch is one of my favorites, given I'm not a very medieval guy (did he just say that? ) I explore the more modern crossbow models and have recently finished gathering the materials to build a matrix and press my own fiberglass reinforced version of the "turbonock" for the railles crossbow I'm designing.



Interesting question is and I believe it is directly linked to our topic here ... the surface area of the fletching(length/height) is directly linked to the fletching offset. Is there any information out there on the net as to how to calculate a balanced helical fletching/nock vs. the surface area vs. the speed of the projectile?

I know that more spin = better shaft stability during flight, but it has an effect on the arrows loss of speed and thus the effective distance.

And the large surface area of the longer/taller fetching is more effected by the wind(causing it to drift with the wind) than the smaller/shorter fletching with smaller surface area.

I believe someone mentioned a book on "man powered projectiles/weapons" when I mentioned something similar before, but after purchasing the materials I was left pretty much broke. ...so if there is any info available on the net, please share.

~ I'll be doing my research, but your opinions matter to me even more.

Thanks,

Ivo

Hey so heard an idea for fletching a bolt today. Basically get some elastic fuel line that the can fit over the tail end of the shaft then put a nock in the other side of the fuel line and push it tight against the shaft. So all you need is a .5 inch or so of fuel tubing to get a nice fletch. Hopefully this make sense I'll try to get down and get some fuel line to try this out. and get some pictures.

What!?!?!

There are some strange fletching ideas out there, but "fuel line"...does this mean actual vanes are cut from/in the stuff? Definitely want to hear more about this garage tech.
