    Brass chasing hammer - burin handle

    Hi!
    I built this couple of tools to try engraving.
    Burin handle is in stainless steel, 18mm diameter, 14cm long, knurled for a better grip. 4x M5 socket set screw blade lock.


    The head of hammer is brass, 25mm diameter, one face rounded , one semi-round. I decided to try an aluminum rod as handle, I will modify if it necessary. I decided to use brass and not steel because I needed also a light and soft hammer in my garage

    Only tip I can offer is barely helpful; you'll spend a lot of time finding the right angle that shears without digging in or skidding. Finish in a recess depends heavily on perfection of cutting edge; carefully honed.

    Thank you!
    I bought 8x gravers with different shape, I'm waiting diamond discs. I read about sharpening templates, many different grit, plus hone and leather to keep the edge sharp. I'm looking for info about the right position and angle, I suppose it will be not an easy work!
    The first thing I would like to engrave is my adjustable horn stand, I would like to add a vernier style reference, it would be hard to keep signs straight and with correct distance.

    How about dividing vernier by your mill for spacing, positioning a rail to guide the manual cutter? Verniers, as you know, break down a distance into 1 more increment in the same linear space. One challenge will be maintaining lines of discreet lengths for sake of readability.

    Hello! I think your idea is really good! Mill for sure is accurate!
    I tried today the first funny step with graver… it's hard to go straight and keep the same angle.

    Well, so far none of the engravers at Beretta are worried about their jobs...Yeah I'm teasing you.
    I know you'll pursue this and do well, just like the plasma speakers, electronics, leatherwork, metal forming, handmade bike frames...
    As far as work in the picture, looked at enlarged; the cutting edge isn't sharp, too flat and far too wide. Look at something engraved. The vee's are smooth and distinct in the bottom and especially the edges. Then you'll know it is sharp. I believe Christophe Mineau here on HMT has video of what the process looks like, and probably a lifetime worth of youtube by others.

    I think you're right, I should check the edge. I tried pushing only with hand, the line is straight and good, but very thin. Pushing a deep Groove by hand is hard.
    I need to learn more for sure!
