Is there a decent technique to drill holes in metal at an angle?
My "new" car has more empty space in the engine compartment, but it has almost no "wall space". There are a couple spots big enough to mount things, but nowhere near big enough to get an electric drill in to drill the mounting holes, nor enough for one of those right angle or flexible cable attachments. Not enough for a center punch and hammer, although maybe enough for a hammerless center-punch (what do you call those?)
But I could get a drill bit in at maybe a 45 degrees angle.
I thought maybe I could put my finger on the bit and hold it in place while I dirilled, but maybe there's a better way.
