Thread: Hellberg in Horn

Those pins are amazing! Can you explain in a little more detail how you did that and what you used both for the doming and for the rod and washers?
Thank you

Great job Matt. Love the pinning. The horn i got was warped too but luckily in a uniform way. Just used it to my advantage by putting the 2 concave sides facing so there was a natural hollow for the blade to sit in.

Thanks!

heirkb, The washers are flat brass number 0's, same as everyone uses from microfasteners. I drilled into a bar of Aluminuim I had with a drill bit that was slightly larger in diameter than the washer and made a shallow "cup" into which I sat a washer. I then stumbled upon a large rivet, (the type that looks like a little sword if you get my drift) refined and polised its spherical end (the head which flares the rivet when you pull it through with the gun) and simply struck it with a hammer, with the ball against the washer in the cup on the Aluminium bar, thus emparting the rivet heads' curvature onto the washer.

The rod is simple 1/16" brass rod from a model shop.

The peening was done with an 8oz polished peen hammer (a bit big really) and about 20000 super light taps ;-) so that there were no flat spots or anything and were mirrored straight away.

- Cheers Oz. This piece or horn was full of ripples in the beginning. I used my most deformed piece for the first attempt, the logic being that starting with a tough piece would teach me more than some of the dead flat pieces I also have. Should allow for better results from me next time. Also, since its such a thin blade I luckily didn't need to create too much of a gap with material curvature or anything.

Cheers!

Gratuitous pin shot!

Great work all around! The pins are amazing and I guess I hadn't been around straights long enough to know that horn scales could look like that! I must have never seen any as thin before.
