Hello folks,

I'm a software developer interested in modular synthesiser DIY so I end up drilling lots of holes in aluminium. (By now you also know I'm not an American.) Last night I blunted some drill bits mounting my vise on my workbench, and Google led me here in search of information about sharpening drill bits.

I busted about four masonry bits drilling bolt holes through a concrete tile to mount my drill press, but we'll just classify those as "consumable" and move on.

I certainly like the idea of making one's tools so I've signed up to get the e-book, and I'll be back to check out more projects.

Cheers,

John :^P
