Metal Arrow Nocks

<< < (3/4) > >>

jaxenro:
I use Shapeways to print them in wax and then do a lost wax casting so my choices are brass, bronze, and sterling silver. Brass and bronze are the same price silver costs more. These are the bodkin points I had done and a picture of the sprue for the target points and nocks plus the matching metal bow nocks. They will require a little cleanup some holes drilled things like that. I was also working on some laminated arrow shafts using wood and laminations to match the bow

willie:
Shapeways looks like a nice service, especially for prototypes. Do you do your own mold making and casting? I presume that you do the final fit and finish?

jaxenro:
No they do the mold making and casting I do the final fitting and polishing although they will do that as well

Essentially for these they print wax than do a traditional lost wax casting from the printed wax model. Works rather well as you can see from theBodkin points which are made for 1/8" shafts

DC:
I'm looking at the bodkins and wondering if they could be cast in the other direction. So that the socket was cast in. Or can't they do thin wall. It just seems that it would be easier to file a point on than it would to machine a socket.

jaxenro:
They can go down to 0.6mm wall thickness

I was thinking a bit different though. Instead of machining a socket for the shaft to go into i was going to end drill the shaft for the pin that protrudes from the end of the point similar to how points are put on hollow shaft arrows
