I thought I'd build a blow dart gun with a laser sight.
It turned out to be a total success.
It works well, and is much more fun than regular darts of the non-blown variety.
Add a loop of cotton running the length of the pin.
I also made one where I used electrical heat shrink instead of cotton binding. It worked well, and was much faster to make, but didn't look as nice as one with binding.
To finish your binding, pass the loose end through the loop.
That's really important string tech. As long as you plan it beforehand and add that loop it's easy, but without the loop, it's next to impossible.
Wool would work better, but I didn't have any.
You can us it like this, but it was a little slow, and not very accurate.
I trimmed mine down a bit.
The point of the tail is to create drag so it flies straight, and with the sharp end up the front where it belongs.
A long strand will make your dart turn off course a bit, and can also get stuck between your lip and the tube, resulting in a blowing noise but no shooting.
An easy way to trim it is to put it into the blow pipe and cut any excess with scissors.
this post about it's possible use in making hand made fishing lures, but basically it's stuff that gets soft at 65 degrees centigrade or so, and sets hard once it cools.
I added three screws that sit through the plastic so I can tighten them against the laser to adjust where it points in relation to the tube. That way, it's easy to adjust and make certain everything lines up properly.
I shot some video while I was sighting it. I placed the laser sighted blow dart gun in a clamp, and repeatedly shot it, and adjusted the screws to get it more accurate. A simple matter of firing, then moving the dot to the same spot as the dart hit.
Things so far...
