No, the length of the fin is 28mm but the hole is 20mm, keeps the centre of gravity a bit more forwardPetitlu wrote:the round completely through the fin?

Should be around 22 grams, I definitely would not want to stand in the way of this thingPetitlu wrote:You know the weight of the tungsten rod?

Based of the performance of the SP-6 round I mentioned earlier, I'm quite confident you will have full penetration. What velocity does HGDT predict?Petitlu wrote:Tungsten vs steel profile, that will win?
Here's what I made so far, a couple of variations because I'm not a CNC machine and making 10 exact copies of the same thing would get boring

I timed the manufacture of fin N<sup>o.</sup> 10, it took me 15 minutes from cutting the delrin rod to the finished product.Petitlu wrote:it how long you need to make a fin?
All that's left now is the pusher plates.
Any other interesting stuff that fits in the barrel you might want to launch?

Machining is fun, you don't realise that time is passingPetitlu wrote:More than 2 hours of work anyway ...
A playmobil!
You need a bigger barrel than that hehe:

Can you show me a photo of this arrow?Yes, an arrow arc carbon, 5mm in diameter!
Tomorrow I want to try and shoot some coins

I've shot CF arrows before, make sure they don't hit something too hard, I've had one explode on impact before.
The larger fins, were troublesome to fit into a 14mm barrel, so 12mm may be a little tight.
I used nitrile plugs used for plumbing as the pusher plate.
And foam or even tissue paper rolled up to keep the arrow head centred. If the arrow is longer than the barrel you could use something like this:

What's the major diameter of the tip of the arrow head? I might have a reasonably easy solution. What about the fins, can they bend to fit the barrel?
In the meantime, tungsten carbide rod fins and pusher plates done much happier with these than the rough cut first ones I sent you.

What about the diameter of the nock? Not sure what the French word is, the green bit of plastic at the end.
