Currently working on a new design and trying to figure out the best/easiest way to make this design consistently and accurately. I’m taking some 2.5mm brass wire and hollowing out the ends of it about 7 to 8mm deep so that I can add some fibers into the ends. I’m the treating it like a bezel and rolling the edge over the fibers to trap them in place.
I did this one by starting with a .8mm hole drilled to depth, then came and hollowed it out with a ball burr, but I think I might have overheated the burr and made it lose its temper (much like myself ) as it now won’t cut without excessive pressure.
Any ideas on an easier/better way to achieve what I’m doing or it just a matter of going much much slower with a ball burr? Thanks for any advice!
