On my first big intricate cut I drilled all of the holes but a quarter of the way in cutting it all turned pear shaped and I was left with wood full of holes..........never again. I now drill about 20 holes cut, repeat, I am not going to waste any more wood in that way again. We all learn by our mistakes. I have also learnt to cut the hardest part first, then if it turns pear shaped in a hurry then I have not wasted a whole heap of time.
