Quixoticgeek<p>After I finished work on my primary project yesterday afternoon, I had a bit of time left until the 3d print finished. So I decided to have a play with my new self made sensitive drilling attachment. </p><p>Aim was to drill a 0.5mm hole in some brass. </p><p>I achieved that with minimal breakage. I've just had a chance to test the hole with gauge pins. </p><p>500µm pin fits.<br>600µm doesn't git. </p><p>I'm considering that a big win. </p><p><a href="https://social.v.st/tags/Machining" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Machining</span></a> <a href="https://social.v.st/tags/Making" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Making</span></a></p>
