I had not used a spiral blade in a long time because I was not that good using one. I would forget that it cut in a 360 and go off and cut someplace that I was not to cut (HA HA) but in looking at how I was going to cut this cross I said I need to try a spiral blade I just had it in my mind that it cuts on all sides and went slow to start and it all worked out. So try something new and take your time and have fun cutting it out ( It's all about the sawdust) Good Luck.
Thanks Mark
