So mostly finished making my copy of @mikey 's straddle knurler. Of course a knurler deserves a knurled knob to adjust it. So I made one out of 1144. I used sulfur cutting oil which is kind of stinky, but it worked well. I was looking at the knurl and wondering how deep it really should be. How much of a point (or non-point) should there be? The knob I made has little craters rather than a point. Points would be uncomfortable, but what should a decent knurl look like (and maintain good knurling wheel life)?

This knurl is on 1.25" OD 1144, skimmed to remove the dull finish then knurled with a straddle knurler. Done with FORM ROL EQL 225 wheels. Do I need to apply a little more pressure? I'm obviously not going to throw out the knob, (it's perfectly useful and decent) but I'd like to know for the next knurl what to target.
