Help with drawing a part

[Mayhem]

Thanks Dave - I'm not looking for someone to draw it up, just to give me some pointers. The drawing from the Kondia manual shows that slot to be 45° to the vertical. I'm just not sure which projection to put it on. The overlap of hidden lines in the top/bottom projection is what has me stumped. There is a lot going on when you look at all the holes.

I could just send the part I have to Ken and ask him to figure it out but I don't want to risk our friendship (that's him on the right!).
Seriously - I want to learn how to draw things like this. I can use CAD, I just don't know how to approach this part.
