Best of Luck!!
I have to order a long shaft burr bit i can't reach the center of the runners too well other than that it's coming along nicely, I'm going through sanding drums like crazy!! lol. I knock off the cast defects with a burr bit and smooth with a drum so far so good, I got the bowls shaped really nice they actually look like a bowl now and not like a half-bowl.
Well I pretty much have done all I am going to do in the combustion area it's pretty slick and shiny my camera phoe dosen't do it any justice.
