Development goes on!
Last year I published here in the blog a instructions for cable bolt shot . Since that time we did some tree climbing caches, where the crossbow with bolts was used. All in all, this is a good thing. After we have adjusted the visor correctly with some sample shots, mostly rich 1 or 2 attempts, until the rope is in place. The cable installation time has been shortened by it very much. Have proved the different materials (weights) of the bolts by which we can control the income level.
But there have also shown weaknesses in the bolt construction, which we now have improved. The most important change is the transfer of the key ring from the end of the bolt to the front - just behind the golf ball.
The rear fixing it ever came to Seilabreissern because the ring has been accelerated with the rope under the bridge and it was targeted at the edges to damage to the pilot line. By moving the attachment to the front of this issue is resolved. The 2nd Advantage of this change is that now we can use a larger, more stable key ring that can withstand longer train when the bolt has sometimes gets caught in the branches.
has also changed the cam at the rear end of the bolt. There we had to damage the shot string to the metal, installed a IKEA pencil. This also works in principle, but the graphite inside a little soft. As a replacement we have used wooden dowels. These are available in different diameters and sizes at the hardware store in the small parts wall and they are normally used for furniture assembly.
All changes will be tested again in hard outdoor use . Should additional enhancements, there's an update here.
