i just googled bow drills and they aren't what i thought they were.
what i have is actually called a pump drill apparently...

Back and forth on Reciprocating Bits « Full Chisel Blog

just thought i would share! was told by my tutors that mine was a bow drill...
maybe this is a common error, or maybe it was just me that had it wrong!

Well, that would really depend on how thick it was I suppose. I think it was probably about 0.6/0.7mm thick and took a few seconds longer than a power drill would have. It's slower, so you have more control.

Did you push really fast?

Why does that look so wrong?

You have to put a bit of pressure behind it and of course, need a sharp bit - a blunt bit won't give good results in anything. I clamp to a bit of scrap timber and use both hands.
