@stolicat seems like that would be an issue…especially if you’re trying to punch something on a vertical surface or a surface that has unevenness or imperfections.
Make a metal punch with a small optical tip (recessed a bit to avoid damage) so you don’t have to swap it out after aligning it.
@blaineg@medz that works for steel, but not non-ferrous (and non-magnetic) metals - i’m often drilling into brass, copper and aluminum, so I guess I’d have to use a little wad of gum on the bottom to hold it in place.
@medz@stolicat This appears to be a machinist’s tool, and they’re generally dealing with flat, horizontal surfaces. Between that, and the apparent weight of the thing, keeping it in place doesn’t seem to be much of a problem. At least for its originally intended use.
