Mekanik,

Actually you want your fireboard and spindle to be the same wood (I usually cut my spindle from the side of the fireboard). If the spindle is harder than your fireboard, it will drill right through it. If your fireboard is harder than your spindle, it will just wear down the spindle. If they are both the same hardness, you will get friction which is what you want. But you want the friction at the bottom, not at the top. Keep the spindle almost pointed at the top to reduce friction there. Your bearing should be real hard (I use antler or beef bone). The bow can be made from anything. Hope this helps.

Semper Fi!
